3 Anchoring and Fastening Systems for Concrete and Masonry Addendum Strong Bolt 2 Wedge Anchor 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 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: Category anchor classification: The Strong-Bolt 2 anchor received classiication as a Category anchor, which is established by performance in reliability tests in accordance with AC9 and ACI.2 test criteria. Category is the highest attainable anchor category for reliability. Tri-segmented clip: Each segment adjusts independently, increasing follow-up expansion should the hole increase in size as a result of a crack Dual embossments on each clip segment: Enables clip to undercut into the concrete thereby increasing follow-up expansion should a crack occur The only " anchor solution approved for 4" concrete thickness: The Strong-Bolt 2 anchor can be installed in cracked concrete with a minimum thickness of ¼", including concrete-over-metal decking High-strength alloy clip on carbon-steel anchors: This special alloy clip offers improved performance Standard (ANSI) fractional anchor: Fits most ixtures and installs with common drill bit sizes and tools Easy post-installation identification: The head is stamped with Simpson Strong-Tie symbol and a letter for length identiication Type 6 stainless-steel clip on stainless steel anchors: 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 Strong-Bolt 2 Wedge Anchor Installation Sequence Head Stamp The head is stamped with the Simpson Strong-Tie No-Equal symbol and the length identification letter. MATERIAL: Carbon-steel stud with special alloy clip; stainless-steel stud with stainless-steel clip ( " diameter only) FINISH: Zinc-plated (carbon steel) CODES: ICC-ES ESR-07 (carbon and stainless steel); City of Los Angeles Pending; UL Pending; FM Pending; Florida Pending TEST CRITERIA: The Strong-Bolt 2 wedge anchor has been tested in accordance with ICC-ES s Acceptance Criteria for Mechanical Anchors in Concrete Elements (AC 9) and ACI.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 NOTE PRODUCT AVAILABILITY AS FOLLOWS: STB2 "- diameter in carbon steel, stainless steel: irst quarter 20 STB2 2"- and "-diameter in carbon steel: second quarter 20 Length Identification Head Marks on Strong-Bolt TM 2 Wedge Anchors (corresponds to length of anchor inches) Mark Units A B C D E F G H I J K L M N O P Q R S T U V W X Y Z From Up To But Not Including
