Simpson Strong-Tie · THD50400H (1/2" x 4")
Heavy-duty screw anchor for cracked and uncracked concrete. Installs in the same hole diameter it drills. Capacity is a strength-design value that depends on embedment, concrete strength, edge distance and spacing — take it from ESR-2713, not from a catalog headline.
Compiled from public manufacturer data and not yet verified against a primary source. Confirm against the manufacturer\u2019s current datasheet before specifying.
