This product is a long wood screw designed for driven fastening into timber and composite boards. Installation is typically by a TX30 bit with a powered driver, where the recess engages the tool to transfer torque efficiently and limit slippage. The partially threaded shaft enables the unthreaded portion to act as a dowel, drawing two members together as the threaded section bites into the lower component. A countersunk head seats into a pre‑formed or pilot hole to produce a flush surface profile. The zinc-plated finish offers basic corrosion resistance appropriate for interior or covered structural joints, and the screw’s geometry supports reliable engagement in woodworking and decking applications where extended length and holding capacity are required.
