We are also the North American importer for ITG Air Filters for road and racing (detailed on pages 8-12). Other fabrication products and accessories are detailed below.

The preferred method of attachment for our ultra lightweight mufflers. These stainless steel clamps slide over the swaged end of the muffler to hold it to your exhaust pipe. “T” bolt is 1/4-28 with an all metal self-locking nut.

T Bolt Clamps

Merge Type Exhaust Collectors

Merge type exhaust collectors are used in everything from INDYCARS and NASCAR stock cars to sprints, midgets and offroad trucks. Merge collectors help reduce exhaust gas turbulence and aid in scavenging exhaust gases away from the cylinder head, resulting in a broader torque curve and higher top end horsepower. The internal pyramid provides a smooth and streamlined transition from the primary header pipes to the tailpipe/exhaust secondaries. The internal and external taper of the collector cone produces the venturi effect, speeding exhaust gas flow and aiding in gas scavenging/extraction.

Please contact us for details on tubing material and wall thickness and collector type (merge or tri-y). All collectors are made-to-order and priced on request. Please also note that:

1) Primary ends are typically sized to fit primary tube OD. 2) Outlet diameter sizing is to your specifications. Outlets can then be tapered to fit larger or smaller diameter exhaust tubing.

Ultra Lightweight Racing MufflersCoast Fabrication has been producing Ultra-Lightweight Racing Mufflers since 1995. Over the years Coast Fab mufflers have become the muffler of choice for many teams competing in both professional and amateur road and oval track racing. The durability of Coast Fab mufflers has been proven by use on the winning car at the Rolex 24 hours of Daytona on multiple occasions. Coast Fab mufflers are also found on sports cars, drag cars, motorcycles, off-road vehicles, high-end road cars, and even some airplanes. They have also been the “spec” muffler for several racing series. Most recently Coast Fab mufflers have been developed to withstand the extreme conditions experienced with rotary powered high performance vehicles.

Dyno tests performed by professional race engine builders have shown that freshly packed Coast Fab mufflers show little or no detriment to horsepower or torque when compared to un-muffled systems.

All Coast Fab mufflers are fully TIG welded, use 100% 304 Stainless Steel construction, and have the unique feature of being easily repackable. Several options for muffling cartridge materials are available; all are easily replaceable. These mufflers are hand built in Huntington Beach, California by racecar fabricators, not mass-produced road car parts adapted for racing. Their fit and finish deserve to be shown front and center, not hidden under the car. In short, these mufflers are designed to offer the highest performance at the lightest weight possible, combined with ease of maintenance, maximum durability, and super fit & finish.

Ultra Lightweight Racing Muffler: All New Modular Design

• Removable/replaceable perforated core which allows thermal expansion as well as easy and fast repacks and rebuilds

• Both inlet and outlet tubes are sized to slip over common exhaust pipe sizes allowing the muffler to be used in the middle or at the end of a system

• Turnouts or extensions can be easily added to the muffler outlet

Two-Stage Muffler

Coast Fabrication’s latest development is a Two-Stage Racing Muffler (pictured below) for use in situations where greater sound reduction is needed and space is at a premium. The first section of the muffler incorporates the same core and packing configuration as the standard Coast Fab muffler. The recently updated second section now includes diffusers and a stainless mesh wrapped core. This feature allows for greater at-track tunability. Two-Stage mufflers have been used successfully worldwide at racetracks with stringent sound regulations. These mufflers are sized specifically to the customer’s requirements.

High Performance Air Filters

Air FiltersIn early 2002, Coast Fabrication, Inc. entered an agreement with Induction Technology Group (ITG) to act as the exclusive North American importer for ITG air filters used in motorsports. We import and specify ITG filters for one simple reason: THEY ARE THE BEST AIR FILTERS MADE.

Why ITG?The ultimate proving ground for any performance product has always been racing. ITG’s racing history is impressive, with numerous wins in World Rally, Touring Cars, Sports and Prototypes, etc. Here in the USA, ITG filters have enjoyed many victories and championships in Sprint car and Midget racing and were also used by Indianapolis 500 winners on multiple occasions. In an arena where only performance matters, ITG filters have been used on the championship winning car in the FIA Formula 1 World Championship on many occasions.

In close cooperation with ITG, Coast Fabrication continues to develop intake systems and air filters for racing, high performance and special applications. PROTOTYPES, SPECIALS, AND LOW VOLUME ORDERS CAN BE EASILY, QUICKLY AND COST-EFFECTIVELY ACCOMODATED. Please contact Gary Donahoe by phone or email ( [email protected]) to discuss your ideas or requirements.

These versatile filters are easily recognizable by their twin bright red bands around the top and bottom; they should not be confused with the many inferior types of foam air filters. The red bands are the visible part of two fiber-reinforced nylon injection moldings which form the structure to which three-layer filter foam is bonded. The outer two layers give optimum filtration and ‘load-up’ capacity, while the inner layer is made of a special fire retardant filter foam. Together they give the best combination for airflow, engine protection, and safety.

» Air Filter SelectionSelection of the filter element depends on the amount of room available. We recommend fitting the tallest filter element you can, with a minimum gap of 1/2” (13mm) over the top of the filter for air to circulate. If rampipes are used there must be a gap between the end of the pipe and the underside of the top of the filter: 3/4” (19mm) is an absolute minimum, and 1 1/4” (32mm) is preferable. NOTE: MOST TYPES OF MEGAFLOW FILTERS ARE AVAILABLE IN EITHER FLAT OR DOMED “SAUSAGE” SHAPE (SEE JC70 ILLUSTRATION OF SAUSAGE TYPE FILTER ON THE NEXT PAGE OF THIS CATALOG).

» Dust Retention Fluid (Filter Oil)

ALL ITG FILTER SYSTEMS ARE DESIGNED TO INCORPORATE THE USE OF FOAM FILTER OIL. FAILURE TO USE THIS SPECIFIC TYPE OF OIL WILL GREATLY REDUCE FILTER EFFECTIVENESS.

» BaseplatesBaseplates for Megaflow filters are available as blanks (aluminum) or pre-cuts (red powder coated steel) to fit a variety of carburetors and injectors. Blank baseplates are stock items and application-specific pre-cuts are typically special order from the factory. Contact us for further information.

Coast Fabrication, Inc and ITG both recommend the use of NO-TOIL biodegradable foam filter oil. Because this product is water-soluble, filter cleaning and maintenance requires only warm water and common liquid dish washing soap or NO-TOIL cleaner. After the filter is shaken off and air-dried (no high pressure air or hot air blowers, please) it can be lightly re-oiled and returned to service.

Aerospace Hardware & Fasteners

During the past few decades, racing vehicles ranging from Indy and F1 cars to offroad trucks have increasingly used aircraft and military specification hardware and fasteners in their construction, and with good reason: as the size of the hardware that racers are accustumed to using decreases, its quality and load-bearing capabilities must necessarily increase. Today’s competition vehicles are significantly faster than their predecessors, and, in almost every case, are both lighter and stronger as well.

Throughout this ongoing evolutionary period, there has been a gradual and inevitable drying up of the once ubiquitous “aircraft surplus” hardware. For quite awhile now, new and current specification aerospace hardware and fasteners have been the name of the game, yet many are unfamiliar with the specifications and applications suitabilities.

The items stocked and sold by Coast Fabrication, Inc. have been tested and proven repeatedly at the highest levels of professional competition to become the choice of knowledgeable builders and racers everywhere (they are currently used and specified by every Formula 1 and INDYCAR team and constructor). In short, they offer the quality and performance demanded in critical, highly-stressed applications.

As always, the aerospace industry continues to engineer and develop new and intriguing fasteners from new materials and with new construction and manufacturing methods. For racing purposes, their cost alone makes them impractical. The AN ( Air Force/Navy), MS (Military Specification) and NAS (National Aerospace Standard) fasteners commonly used in racing all originated 30 to 50 years ago. That the evolutions of these specifications are still in use for today’s military and civilian aircraft fasteners is a testament to their lasting suitability and the rigid quality control standards they pioneered. The fact that these basic fastener groups have remained the same for so long means that prices and availability are both reasonable.

Bolts

1) Within a given diameter (i.e. 1/4, 3/8, 1/2, etc.) of any AN/MS/NAS series, all bolts will have the same thread length, no matter how long the bolt.

2) The thread lengths for each series bolt are on the specification prints and in chart form on p. 29 for all sizes from #10–32 through 3/4–16.

3) In the commonly specified MS and NAS series bolts, the dash number is the grip in 1/16” (0.0625”) increments, e.g. –18 = 18 x 0.0625” = 1.125” = 18/16”.

4) Thus, to determine the overall length of a bolt, simply add the thread length (for that series and diameter) to the grip length you desire, e.g. NAS 1306–24: grip is 1.50” + threads: 0.578” = 2.078” overall length.

5) In AN series bolts, you must have a chart or bolt gauge to determine lengths, grips or part numbers. THE DASH NUMBERS DO NOT INDICATE GRIPS OR OVERALL LENGTHS.

Bolt Load Capacity Calculations Load calculations for bolts are always defined by the area of a circle (πr2: π =3.1416; r= radius of circle or 1/2 the diameter)

The minimum load capacity is calculated at the area it will bear upon times (x) minimum bolt strength rating.

Shear Loads: Calculate at minimum dimension for full (grip) diameter. Example NAS1304: r = .1243; Area = π r2 = .049 square inches. .049 square inches x 95,000 psi (shear rating) = 4655 lb @ full diameter; single shear Tensile Loads: Calculate at maximum pitch diameter: see chart on page 72 Example NAS1304: r = .1134; Area = π r2 = .0404 square inches. .0404 square inches x 160,000 psi(tensile rating) = 6464 lb

General Information & Formulas

The Parts of a Bolt

The key dimension on aerospace bolts is the grip length. The grip is the unthreaded portion of the bolt underneath the head (see illustration below).

15


AN3 – AN20 SERIES: AIRFRAME BOLTSThe most commonly available aircraft-spec bolts: these hex head, fine threaded fasteners have a minimum tensile strength of 125,000 psi and a minimum shear strength of 75,000 psi. Length of thread is consistent within each diameter, and grips (unthreaded shank) are available in 1/8” increments beginning at 1/16”. Vastly superior to “Grade 8” tension bolts for almost all shear-type, race car applications.

NAS1103/6203 AND NAS1303/6603 SERIES: CLOSE TOLERANCE BOLTSThese fine-threaded, dimpled-head hex bolts have a minimum tensile strength of 160,000 psi and a minimum shear strength of 95,000 psi. Thread length is consistent within each diameter (1103/6203 series have a shorter thread), and grips are available in 1/16” increments beginning at 1/16”. Used in applications where a premium-quality, high strength bolt is necessary.

NAS624 / MS21250 SERIES: 12 POINT EXTERNAL WRENCHING BOLTSThese fine-threaded, twelve-point head bolts have a minimum tensile strength of 180,000 psi and a minimum shear strength of 108,000 psi. Thread length is consistent within each diameter and standard grips are in 1/8” increments beginning at 1/8”. These bolts also have a large radius between the bolt head and shank for additional strength. This requires the use of the MS20002C series beveled washer under the head. A “Superbolt” for the most demanding applications. Please note that odd number grips, i.e. –15, –23, etc., are not standard and may not always be available. Please inquire for specifics.

MS20004 SERIES: INTERNAL WRENCHING BOLTSUsed where construction necessitates the use of an internal wrenching (Allen hex socket) bolt, they are fine-threaded with a minimum tensile strength of 160,000 psi and a minimum shear strength of 96,000 psi. Standard grips are in 1/8” increments beginning at 1/8”. Like the NAS624 series, they require the use of the MS20002C beveled washer under the head. Another alternative for critical or limited access applications. PLEASE NOTE THAT HEAD BASE DIAMETERS AND HEAD HEIGHTS ON TWELVE-POINT HEAD AND INTERNAL WRENCHING BOLTS ARE IDENTICAL. Note also that like 12 point bolts, odd number grips are not standard and may not always be available. Please inquire for specifics.

NAS6303 SERIES: HIGH TEMPERATURE ALLOY HEX BOLTSIdentical in external configuration to the NAS6203 series bolts listed above. Made from A286 stainless steel alloy, rated for 1200°F operation. Minimum tensile strength is 160,000 psi; minimum shear strength is 95,000 psi. The brake hat bolt of choice for all serious race cars.

NAS1102 SERIES: TORQSETSThese are fully threaded (UNF) 100° flat head screws with a torq-set drive recess; 160,000 psi tensile strength. Used where high strength, a large head area, and a positive drive are required (wings, undertrays, etc.). We also stock the drive tools and mating Tinnerman washers (p. 44).

OTHER MS AND NAS BOLTSThe bolts described above represent over 80% of current race car chassis usage. However, there are many other configurations and materials available under MS and NAS part numbers: contact us with your requirements and we can make a recommendation and provide technical details. See p. 31 for information on custom configurations.

NOTE: Tensile strengths on AN3-AN20 bolts are equal to SAE grade 5. Tensile strengths on all other series are at least equal to SAE grade 8.

Torque & Fastener Matching Information

In most race car chassis and aircraft airframe applications, the bolts used are loaded in shear. The torque values given in the NAS torque chart (opposite page) are adequate and appropriate for this type of usage. For aerospace bolt applications subjected to high tensile loadings and for aerospace nuts and bolts matched to fasteners of other grades and thread classes, see the notes below:

A) For applications requiring high installation torque values and using standard NAS bolts: achievable torque is dependent on plating, length of thread engagement, class of mating threads and lubricant (if any). For maximum fatigue resistance and clamping force in the bolted assembly, we want to produce a level of installed tensile stress that is just below the yield strength of the bolt material (typically around 85% of the ultimate tensile strength). Achieving this ensures that the stresses encountered in the assembly/tightening process will be the most the bolt ever sees. At the yield point, the bolt will undergo “plastic” deformation (permanent stretch). Bolts for critical applications should be test-torqued to determine the point of measurable permanent stretch. As a rule, approximately 90% of this value will give the best performance in a bolted assembly. Example: ’93 INDY-LOLA ring gear bolts NAS 1307-4H – with light lubrication, these bolts stretch permanently on a consistent basis between 105 and 110 ft/lbs of installed torque. 90% of this value gives an assembly torque of 95 ft/lbs. B) The mating of aerospace spec (MS•NAS•AN) bolts and nuts to fasteners of other specifications and thread classes can cause problems. Nut splitting failures are primarily caused by overtorquing and/or thread class mismatches. Generally, NAS wrenching torque values should be reduced when aerospace nuts are matched with non-aerospace bolts or studs. Wrench torque values in the NAS nut tables below are achieved under laboratory conditions using aerospace spec bolts (Class 3 threads) of higher strength than the nuts they are mated to. THE TABLES DO NOT STATE, NOR SHOULD ONE INFER THAT THIS PERFORMANCE CAN BE DUPLICATED WITH OTHER TYPES OF FASTENERS AND/OR CLASSES OF THREADS. For applications requiring high clamping forces, 12 point nuts should be used whenever possible. Their greater thread contact area and higher rated strength make higher wrenching torque values possible. As a general rule, the wrenching torque values for aerospace spec nuts should be reduced approximately 25% as a starting point when these nuts are mated to non-aerospace bolts or studs.

Washers

As we all learned in grade school, the washer’s basic function is to act as a load bearing face to prevent a bolt and/or nut from digging into the surfaces of what is being clamped together. Washers also make good shims. Those listed below are the most regularly specified.

A high strength, heat-treated washer which must be used (“C” version) with the MS/NAS twelve point and internal wrenching bolts. The chamfer matches the radius under the bolt head. Also good for use with heavy torquing loads where ordinary steel washers would gall.

Note: Although the MS20002 washer will fit over the shanks of standard NAS (1103/1303/6403 etc.) hexbolts, the washer ID is small enough that it will usually “crash” with the bolt head-to-shank radius. DO NOT USE MS20002 WASHERS UNDER THE HEAD OF STANDARD NAS HEX BOLTS.

Airframe Control Bearings

These high capacity, low torque, lightweight, close tolerance radial ball and roller bearings are in widespread use in F1 and other top level motorsport series. Excellent for control of oscillatory motion, most have teflon seals and come standard with high temperature (325ºF) milspec synthetic grease.

A Cautionary Note: These listed series bearings are currently manufactured by only three companies - RBC/Torrington/Fafnir, NHBB Aerospace, and Schatz. All have long production lead times and, because not all of these listed series are current

“standards” in aircraft/aerospace, it is critical to confirm availability on parts before design-specifying. Also, we strongly recommend procurring ample supplies of required items when available, as stock can appear and vanish from the open market quite rapidly. Major price fluctuations are also not uncommon. We can hold stock and release over a period of up

to 6 months with your purchase order. Contact us for further details.

We can supply the following Milspec/Fafnir series: MS27630/KP MS27641/KP-A MS27642/KP-B MS27642-S/MKP-BMS27643/DSP MS27644/DPP MS27645/KSP MS27646/B500DDMS27647/DW & GDW MS27648/KP-BS MS27649/AW-AK MS21428/MB500DD

Live Lock Panel Fasteners: General Information Definitions & Descriptions

1. The stud-nut (e.g. CA1820-1; CA1820-3) is retained with the top panel via a retaining ring (CA18377; CA1825; CA1826-1). 2. The receptacle (CA18157: rivet on; CA18062: thread in) is mounted in the mating panel. 3. Spring-loaded ratchet plates in the receptacles lock the stud into place and resist vibration & loosening WITHOUT THE NECESSITY OF PREVAILING TORQUE; as long as the stud-nut is engaged on the receptacle, it is locked into place. Further tightening does not increase its strength or vibration resistance. 4. Rated Strength: 1,650lbs min Ultimate tensile strength 1,800lbs min Ultimate single shear strength thru shank 1,500lbs min Ultimate single shear strength thru recess 5. See illustrations below.

Selection & Care

1. Since both the studs and receptacles employ “4 lead” threads, (#8-32 is the thread size for CA18157, CA18062, CA1820) each full turn of a stud will produce 4 times the vertical thread displacement of a standard #8-32 bolt (e.g. studs will act as if they are #8-8: 8 full turns travel equals 1 inch instead of 32 turns to travel 1 inch. 2. MAXIMUM ENGAGEMENT ON ANY STUD IS 1.75 TURNS; TYPICAL INSTALLATIONS SHOULD BE 1.5 TURNS OR LESS. Remember: FURTHER TIGHTENING DOES NOT ADD TO STRENGTH OR VIBRATION RESISTANCE! 3. FACTORY RECOMMENDED TIGHTENING TORQUE IS 30 lb./in. 4. The factory recommends that the studs be selected so as not to exceed the grip length (“g” dimension in the chart) indication for each size. Grips close to the maximum for a given stud dash number are sometimes better served with the next longer stud dash number.

Failures: Typically occur in receptacles; cracked, shattered, or broken ratchet plates, caused by (in declining order): 1. OVER-TIGHTENING: (attempting to go past coil-bind on the spring). 2. Use of a male stud-nut with a split or otherwise damaged nose, that unevenly contacts and/or “tips” the top ratchet plate. 3. Repeated shock loads (NEVER USE AIR TOOLS FOR INSTALLATION OR REMOVAL!) or continuous vibration, which causes the plates to rapidly load and unload against the stud.

Heat Reflective Tape

Coast Fabrication Inc currently offers two heat reflective tapes. Both of these tapes are lightweight, self-adhesive materials and are currently used in F-1, Indy Cars, ALMS, etc. Material specification and “apples-to-apples” comparison tests between our tapes and the corrugated “gold” material that is in universal circulation follow. All 3 tapes were applied to an aluminum panel (0.063” 3003H14) and a constant heat source was fixtured at noted distance. Heat was applied to the front (tape) side and the temperature was measured on the back side.

AeroCatch2 ® - For Marine and Edge-Latching Applications

The popularity & success of the AeroCatch - the perfect modern alternative to conventional hood pins - resulted in the demand for an equally practical slide-pin attachment system suitable for marine applications where edge-latching is required. Marine users admired the simplicity and security of the AeroCatch in its original version, but asked for a version which eliminated the conventional threaded-pin mount. To meet this requirement, the shear sliding pin was lengthened to extend past the AeroCatch housing and into the mounting frame for the panel. The versatility and durability of the AeroCatch2 has been proven in the demanding world of powerboat racing.
