Description Six-sided internally threaded fasteners whose thickness is .875 D where D is the nominal nut size and 1.5D is their width across the flats,made from austenitic alloys as described below.
Applications/Advantages
Designed for use with stainless steel bolts and screws with a specified minimum tensile strength equal to or less than the specified proofstress of the mating nut. Both types of stainless are corrosion resistant with 316 stainless having greater such resistance as well as
superior strength at raised temperatures.

DescriptionA six-sided internally threaded fastener which is both thicker and wider across the flats than a same-sized finished hex nut, made of 18-8 stainless steel. Nuts in sizes 7/16 & smaller shall be double chamfered. Larger sizes are either double chamfered or chamfered on
top with a washer faced bearing surface.
Applications/Advantages
This is the strongest of all 18-8 stainless hex nuts because of its greater length of thread engagement and greater resistance to dilation(widening or stretching).
Material Nuts shall be made from one of the following austenitic stainless alloys: 303, 303Se, 304, XM7, all of which are characterized as havinga chromium content of 18% and a nickel content of 8%.

Description A six-sided internally threaded fastener which is both thicker and wider across the flats than a same-sized finished hex nut. Nuts in sizes 7/16& smaller shall be double chamfered. Larger sizes are either double chamfered or chamfered on top with a washer faced bearing surface.
Applications/Advantages
This is the strongest of all comparably-graded nuts because of its greater length of thread engagement and greater resistance to dilation(widening or stretching). Grade-A nuts are used with low-carbon heavy hex bolts. Grade-C nuts are recommended for use with A-325
structural bolts. Grade-2H nuts are recommended for use with bolts in high-pressure and high-temperature service. Grade-DH nuts arerecommended for use with A-490, Type-1 structural bolts and Grade-DH3 nuts for use with A-490, Type-3 structural bolts.
Material
Nuts shall be made from a steel which conforms to the following chemical composition requirements (heat analysis)--Grades-A & C-- Carbon: 0.55% maximum; Phosphorus: 0.12% maximum; Sulfur: 0.023% maximum.
Copper: 0.20% minimum; Chromium: 0.45% minimum; (Either Nickel: 0.20% minimum or Molybdenum: 0.15% minimum, may be used).
HeatTreatment
Grade-2H: These nuts shall be heat treated by quenching in a liquid medium from a temperature above the transformation temperature andtempering at a temperature of at least 850°F.
Grades-C, DH & DH3: These nuts shall be heat treated by quenching in a liquid medium from a temperature above the transformationtemperature and tempering at a temperature of at least 800°F.
Description A six-sided internally threaded fastener which is only 2/3 the thickness of a full form nut.
Applications/Advantages
Jam nuts are tightened against the work surface and a finished or heavy hex nut is tightened against the jam nut to keep it fromloosening.
Material
Steel: Nuts shall be made from a low carbon steel which conforms to the following chemical composition requirements-- Carbon:0.47% maximum; Phosphorus: 0.12% maximum; Sulfur: 0.23% maximum.
Stainless: Nuts shall be made from one of the following austenitic alloys: 303, 303Se, 304, XM7, all of which have a chromiumcontent of 18% and a nickel content of 8%.
Heat TreatmentStainless: The austenitic alloys develop their strength through work hardening during the fastener manufacturing process, as seenfrom the hardness properties below. The only heat treatment normally available on austenitic stainless alloys is annealing, which is
done at approximately 1900°F to a dead soft condition and is not normally thermally reversible.
Description A hex nut pre-assembled with a free spinning external tooth lock washer. The locking action is achieved when the nut is tightened againsta bearing surface as the teeth of the lock washer dig into it.
Applications/Advantages
This is the most popular type of locknut because of its versatility, cost and ease of installation. Doesn't gall screw threads.
Material Steel: Nuts-- AISI 1008-1020 or equivalent steel; Washers-- 1050-03 or equivalent steel.Stainless: Nuts-- One of the following austenitic alloys: 303, 303Se, 304, XM7; Washers-- SAE 300-305 stainless.
*Product standards require all grade-marked nuts 1/4” diameter and larger to have a raised or depressed insignia identifying its manufacturer. “X” represents onelocation such an insignia may appear.
DescriptionGrade-C Automation Lock Nut: An all-metal, one-piece hex nut which derives its prevailing torque characteristics from controlled
distortion of its top threads from their normal helical form to a more elliptical shape.Grade-GT Flange Style Automation Lock Nut: Similar to Grade-C but with a flange on the bottom side of the nut.
Applications/Advantages
Grade-C: These nuts are reusable and can withstand temperatures of up to 4500F. Can withstand severe vibration and shock loads.Frequently used in farm machinery, plus the automotive and related metalworking industries.
Grade-GT: Has a lower, more uniform bearing stress to clamp force ratio. This style reduces inventory (by eliminating a washer) and in-place cost. It is designed to be used specifically but not exclusively with grade-8 frame bolts.
Material C1022 - 1045 steel.
Heat Treatment Nuts are heat treated to the austenitizing temperature of the material of which the nut is made, quenched in a proper medium to obtain apredominately martensitic microstructure, and tempered to the specified hardness.

DescriptionHex nut with two or three, round or rectangular indentations, compressed onto the flat sides of the nut equidistant from each other.The compressions create slightly distorted center threads resulting in a controlled locking action when the threads of the mating part
become engaged.
Applications/Advantages
This is the least expensive prevailing torque type of nut, designed for use with machine screws and low-carbon bolts. It allows forautomatic assembly because the top and bottom of the nut are identical. It creates a locking action even without being fully threaded
onto its mating screw.

DescriptionHeat treated hex nut with a nylon-filled collar at its back end. The nut shall be grade-marked in one of two ways: (1) with double
notched corners or (2) with six symmetrically spaced identical symbols on the chamfered surface on top of the nut. When the cap-screw or bolt reaches the collar, the threads and nylon form a tight, frictional fit, restricting movement of the cap-screw or bolt when it
is subjected to vibration. The nylon insert comes in various colors.
Applications/Advantages
Designed to be used in structural applications with Grade-8 cap-screws or bolts which have a minimum tensile strength of 150,000 psi.or greater. Some such applications include engines, turbines, hydraulic cylinders, railroads and aerospace. Nylon insert nuts are not
designed to be used at temperatures over 250 0 F.

DescriptionHeavy hex nut with a nylon-filled collar at its back end. When the cap-screw or bolt reaches the collar, the threads and nylon form atight, frictional fit, restricting movement of the cap-screw or bolt when it is subjected to vibration. The nylon insert comes in various
colors.
Applications/Advantages
Has greater surface area than NM-series nuts, making wrenching easier. Designed to be used with cap-screws and bolts which have aminimum tensile strength not greater than 90,000 psi.. Used in bridge and building construction, material handling, heavy equipmentand oil field machinery. Steel nylon insert stop nuts are less expensive than grade-C automation lock nuts. Nylon insert nuts are not
designed to be used at temperatures over 2500 F.

DescriptionAn all-metal, one-piece, hex-shaped lock nut with a round collar at its back end. The collar is segmented with opposed slots cut into it
above each corner of the nut. When the screw or bolt reaches the collar, the slotted portion expands which creates the prevailingtorque locking action. The light hex variety has a lesser across the flats dimension resulting in a lighter-weight part with the same
strength as a heavy hex variety.
Applications/Advantages
The full height light hex lock nut has the same locking capability as the heavy hex FlexLoc® nut, but with greater wrench clearance.FlexLoc nuts maintain their locking strength through 15 removals and re-applications, and at temperatures up to 550°F (450°F if zinc
or cadmium plated). They have superior resistance to vibration compared to all other lock nut varieties and do not gall threads.
