Simpson Strong-Tie 5/8" x 4-1/2" Strong-Bolt 2 Wedge Anchor, Carbon Steel, Zinc, 2-7/16" Thread (20-Pack)

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 nachor location; this feature significantly increases the ability of Strong-Bolt 2 to carry load if the hole expands.
