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.
This Simpson product is designed for construction, connector, fastening, anchoring, and structural applications where dependable performance, durability, and jobsite-ready installation matter.
