The Strong-Bolt® 2 wedge anchor is the next-generation solution for cracked and uncracked concrete. Following rigorous testing according to ICC-ES acceptance criteria, the Strong-Bolt 2 anchor received classification as a Category 1 anchor, the highest attainable anchor category for performance in cracked concrete under static and seismic loading. Available in stainless steel, it is code-listed by ICC-ES under the 2009 IBC requirements for post-installed anchors in cracked and uncracked concrete.
FEATURES:• Category1anchorclassification: The Strong-Bolt 2 anchor received classification
as a Category 1 anchor, which is established by performance in reliability tests in accordance with AC193 and ACI355.2 test criteria. Category 1 is the highest attainable anchor category for reliability.
• Tri-segmentedclip: Each segment adjusts independently, increasing follow-up expansion should the hole increase in size as a result of a crack
• Dualembossmentsoneachclipsegment: Enables clip to undercut into the concrete thereby increasing follow-up expansion should a crack occur
• The3⁄8"anchorsolutionapprovedfor31⁄4"concretethickness: The Strong-Bolt 2 anchor can be installed in cracked concrete with a minimum thickness of 3 ¼", including concrete-over-metal decking
• High-strengthalloycliponcarbon-steelanchors: This special alloy clip offers improved performance
• Standard(ANSI)fractionalanchor: Fits most fixtures and installs with common drill bit sizes and tools
• Type316stainless-steelcliponstainlesssteelanchors: In addition to superior corrosion resistance, a stainless-steel clip offers “memory” that contributes to the anchor’s performance if the hole increases in size because of a crack
MATERiAl: Carbon-steel stud with special alloy clip; stainless-steel stud with stainless-steel clip
FINISH: Zinc-plated (carbon steel)
CODES: ICC-ES ESR-3037 (carbon and stainless steel in concrete); IAPMO ES ER-240 (carbon steel in CMU); City of Los Angeles RR25891; Underwriters Laboratories File Ex3605; Factory Mutual 3043442; Florida – Pending
TEST CRiTERiA:The Strong-Bolt 2 wedge anchor has been tested in accordance with the ICC-ES Acceptance Criteria for Mechanical Anchors in Concrete Elements (AC 193) and ACI 355.2 for the following:• Static tension and shear loading in cracked and uncracked concrete
• Seismic and wind loading in cracked and uncracked concrete
• Performance in cracked concrete
• Performance in lightweight concrete over metal deck
iNSTAllATiON: •DonotuseanimpactwrenchtosetortightentheStrong-Bolt2anchor. Caution: Oversized holes in the base material will make it difficult to set the anchor and will reduce the anchor's load capacity.
