Product Description
The Simpson Strong-Tie Strong-Bolt 2 Wedge Anchor (3/8 in. x 2-3/4 in., Type 316 Stainless Steel) - is a high-performance wedge-type expansion anchor engineered by Simpson Strong-Tie for demanding concrete fastening applications, including those subject to seismic and high-wind conditions. Constructed entirely from Type 316 stainless steel, this anchor delivers long-lasting corrosion resistance across a wide variety of service environments. Dual undercutting embossments on each clip segment enable secondary expansion should a crack form and intersect the anchor location, significantly increasing load-carrying capacity if the hole expands.

Frequently Asked Questions
- What type of concrete applications is the Strong-Bolt 2 approved for?
- The Strong-Bolt 2 is code listed for both cracked and uncracked concrete applications. It is also qualified for static and seismic loading conditions covering seismic design categories A through F, making it suitable for use in high-seismic and high-wind environments.
- What drill bit and wrench size are required to install this anchor?
- This anchor installs with a 3/8 in. drill bit and requires a 9/16 in. wrench size. Its standard (ANSI) fractional sizing ensures compatibility with common drill bits and tools.
- Why is Type 316 stainless steel used for this anchor?
- Type 316 stainless steel provides long-lasting corrosion resistance, making this anchor suitable for a wide variety of service environments where exposure to moisture or corrosive conditions is a concern. All components - including the anchor body, nut, washer, and clip - are made from Type 316 stainless steel.
- What is the purpose of the dual undercutting embossments on the clip segments?
- The dual undercutting embossments on each clip segment enable secondary expansion should a crack form and intersect the anchor location. This feature significantly increases the ability of the Strong-Bolt 2 to continue carrying load if the hole expands, enhancing performance in cracked concrete conditions.
