Simpson Strong-Tie STB2 Strong-Bolt 2 Wedge Anchor - Stainless Steel, Type 316 Stainless
NEW fully assembled Strong-Bolt 2 anchors available! The unassembled versions have limited availability; see product information table below for fully assembled options.
Code listed for cracked and uncracked concrete applications, the Strong-Bolt 2 wedge-type expansion anchor is an optimal choice for high-performance even in seismic and high-wind conditions. 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 Strong-Bolt 2 to carry load if the hole expands. The Strong-Bolt 2 stainless-steel wedge anchor offers long-lasting corrosion resistance for a wide variety of service environments.
