03Technical description

zinc-plated lag screw with coarse wood thread is a TECTUL reference for structural wood, posts, supports, bases, hardware, and fastenings requiring a coarse wood thread with greater grip. The actual lot reports material carbon steel, sale by unit and zinc-plated, inch thread. It is distinguished by the coarse wood thread and hex head for wrench tightening; it is not sheet metal screws or small wood screws. To select without errors, validate head style, drive, finish, commercial diameter, and length against the sample or drawing. ASME B18.2.1 includes public references for hex bolts and lag screws in inch sizes; installation requires a compatible pilot hole. We do not publish a single torque or capacity because the result depends on base material, thickness, hole preparation, lubrication, coating, head bearing, vibration, and tightening method.

Installation recommendations

Drill a pilot hole when the wood is hard, near the edge, or the size is large.
Confirm diameter and length before installation; a similar size can damage the thread or leave insufficient fastening.
Use a bit, socket, or driver in good condition to avoid stripping the head or marking the finish.
Do not substitute zinc-plated, black oxide, or stainless steel without validating moisture, washdown, or outdoor exposure.
Tighten to a firm seat without splitting the wood or sinking the head excessively.
