Description

These wood screws are designed to fasten timber and engineered boards by converting rotational drive torque into axial clamping force. The screw’s threaded portion cuts into the substrate as it advances, drawing mating components together while the unthreaded shank portion (where applicable) allows shear transfer between pieces. Installation is performed with a TX20 bit, enabling efficient use with power drivers or manual tools; the countersunk head seats into a prepared or self‑bored recess to produce a flat finish. Typical uses include furniture assembly and joinery in MDF and particleboard where reliable mechanical fastening and a discrete head finish are required.
