Fischer 573102 Spax screw 50 mm TX 500 pc(s)

This wood screw is a self‑tapping fastener intended for joining timber and board materials. Its shank and thread engage particle and timber substrates to pull components together while the countersunk head sits flush with the surface once driven. The Torx TX20 interface transmits high torque with minimal slippage, making it suitable for use with impact drivers and screwguns. The zinc‑plated surface layer gives enhanced resistance to surface corrosion compared with bare steel, helping maintain performance in typical interior environments. Installation involves pre‑positioning, driving the screw through the top component into the receiving material and tightening until the head is level with the face.
