lag-master is the
professional’s choice

Lag-Master is a heavy-duty, code-compliant wood screw engineered for structural framing jobs and designed to replace 3/8” lag-screws. The type-17 point eliminates pre-drilling and makes for fast installations with even the densest woods. The draw-tite shank pulls trusses and 2 and 3-ply dimensional wood together rather than pushing them apart as the fastener is driven in. Lag-Master’s hex-washer head is designed for applications where greater torque is required and it provides a larger bearing area for greater holding power.

Lag-Master is tested and supported by engineering data that conforms to the current ICC standards – ICC-ESR#3531. More Information
