Description

This wood fastening is designed to join timber and panel materials by converting rotational torque into axial pull and thread bite. During installation the screw is driven with a TX20 bit; the threads cut into the substrate to draw parts together while the unthreaded portion aligns components. The countersunk profile ensures the fastener sits flush with the surface when driven home, enabling concealed finishes or direct contact between parts. The zinc‑plated finish provides a protective metallic coating suited to interior joinery environments. Typical uses include furniture assembly, cabinet‑making and general timberwork where a compact, high‑engagement fastener is required.
