With the Spax s chipboard screws, you build solid and long-lasting timber joints in furniture, battens, and solid wood structures. The full thread design with a thread length of 61 mm reliably absorbs tensile and compressive forces across the entire 70 mm length. Thanks to the countersunk multi head, the screw sinks cleanly and flush into the timber surface, while the PZ2 drive prevents cam-out and bit slipping. The innovative Wirox coating also delivers significantly higher corrosion protection than standard zinc-plated steel. This allows you to work fast, neatly, and with full control on interior and covered outdoor installations.
