Fischer 573074 Spax screw 80 mm TX 200 pc(s)

This wood screw is a fastener designed to join timber and panel materials by converting rotational torque into axial clamping force. The partially threaded profile allows the unthreaded shank to act as a dowel, drawing components together while the thread bites into the receiving board to maintain pull‑out resistance. Installation is typically performed with a TX30 bit using powered drivers, which controls torque transfer and keeps the head flush as it seats. The zinc‑plated finish provides basic surface protection in internal environments, and the geometry suits repetitive, heavy‑duty woodworking tasks such as structural timber joins and assembled timber decking where reliable mechanical engagement is required.
