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 is available in zinc-plated carbon steel, mechanically galvanized carbon steel, and Type 304 and Type 316 stainless steel
