With Spax s chipboard screws, you assemble timber panels, furniture, and skirting boards with speed and precision. The milling ribs beneath the countersunk head ensure the screw sinks cleanly and flush into the wood without splintering. Thanks to the integrated 2.5 mm centre head hole, you can easily press in decorative cover caps to conceal screw heads neatly in your cabinetry work. The 4.5 x 25 mm full thread design delivers strong holding power in thin timber joints, while the advanced Wirox coating provides durable corrosion protection. Driven with a standard Pozidriv PZ2 bit, you achieve a secure, professional finish on every job.
