Fastenmaster FMHLGMTT412-50
FastenMaster HeadLOK is a heavy-duty, flat-head structural wood screw engineered to replace traditional 3/8" lag screws with faster installation, higher shear values, and no predrilling required. Now upgraded with the TORX ttap Drive System, HeadLOK delivers superior bit engagement and a stable, wobble-free drive that dramatically improves speed and accuracy on the jobsite.
Designed for demanding structural applications, HeadLOK is backed by engineering data conforming to ICC-ES ESR-1078, ensuring code-compliant performance in headers, beams, engineered lumber, and general framing. The advanced ProjectLife Coating provides long-term corrosion protection and is guaranteed for the life of the project, making HeadLOK ideal for exterior construction environments.
With its improved drive system, high structural capacity, and corrosion-resistant design, HeadLOK gives contractors a reliable, high-strength alternative to lag screws-without the slow, labor-intensive predrilling.
