Midwest Fasteners Coarse Thread Hot Dip Galvanized Steel Hex Head Lag Screw

Midwest Fasteners Coarse Thread Hot Dip Galvanized Steel Hex Head Lag Screw

The Midwest Fasteners Hex Head Lag Screw family delivers a heavy-duty steel fastener built for structural wood-to-wood and wood-to-masonry connections that call for a hex drive and high installation torque. Constructed from steel and finished with a Hot Dip Galvanized coating, these coarse-thread lag screws resist corrosion in outdoor, exposed, and high-moisture environments where standard plated fasteners fall short. The lineup spans diameters from 1/4" through 1/2" and lengths from 1" through 12", giving contractors and maintenance crews the flexibility to match the correct screw size to the job at hand, with a hex head that allows fast, controlled installation using a standard wrench or socket.
