FastenMaster has upgraded its popular HeadLOK Structural Wood Screws with the TORX ttap Drive System for enhanced installation performance.
TORX ttap is a premium drive system, which combines the ease of a TORX drive with a patented ttap stability button. This innovative design provides superior bit engagement for a stable, wobble-free installation, while preventing fastener strip-out during installation.
HeadLOK fasteners feature a large flat head design with chamfer for increased strength, a sharp point for faster installation, aggressive thread design for maximum engagement and holding strength, and a 3/16" diameter shank that offers higher design shear than 3/8" lag screws. The fasteners come in lengths of 2-7/8", 4-1/2", 6", 8" and 10", with additional lengths available for special order.
