Simpson Strong-Tie 5/8″ x 4-1/2″ Strong-Bolt 2 Wedge Anchor, 2-7/16″ Thread (Pack of 20)

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.
