With the Spax s chipboard screw, you assemble furniture, chipboard, MDF, and solid timber with a neat and flush finish. The countersunk head with milling ribs sinks smoothly into the material without splitting the wood or requiring separate pre-countersinking. Thanks to the integrated 2.5 mm centre-drilled head, you can easily fit standard decorative cover caps to conceal fastenings across your cabinetry. The continuous full thread and secure PZ2 drive deliver maximum grip and hold strong against heavy loads and tension. In addition, the wirox coating provides significantly higher corrosion protection than standard zinc plating for all indoor fittings.
