Simpson Strong-Tie Strong-Bolt 2 STB2-37334C50 Wedge Anchor, 3/8 in Dia, 3-3/4 in L, Carbon Steel, Zinc Plated Silver

Code listed for cracked and uncracked concrete and masonry 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.
