The Titen HD Heavy-Duty Screw Anchor THD50400H 1/2” x 4”, from industry leader Simpson Strong-Tie, is the contractor's choice for the toughest concrete and masonry applications. Use on cracked AND uncracked concrete as well as uncracked masonry. The THD50300H is strong enough to withstand seismic conditions, and it’s been tested at 50% less torque than its competitors.
