With Spax chipboard screws, you assemble furniture, MDF, and timber structures quickly and securely. Thanks to the countersunk multi head, the screw sinks cleanly and flush into wood without damaging the workpiece surface. The full thread over 25 mm delivers high pull-out resistance across wooden panels, while the PZ2 drive ensures solid bit engagement and prevents cam-out during fastening. In addition, the Wirox coating effectively protects the steel from corrosion during interior construction and cabinetry projects. Supplied in a pack of 1000 pieces measuring 4 x 30 mm, these screws give you complete control and a neat finish on every job.
