Strong-Bolt 2 1/2 in. x 5-1/2 in. Type 304 Stainless-Steel Wedge Anchor (25-Qty)

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.
