Code listed for cracked and uncracked concrete, and masonry applications, the Simpson Strong-Tie® 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.
