With Spax s chipboard screws, you achieve strong and neatly finished joints in timber and panel materials. The milling ribs under the countersunk head allow the screw to seat flush without damaging the wood surface. Thanks to the integrated 2.5 mm head hole, you can easily insert matching cover caps with pins to conceal screw heads in cabinetry and interior fittings. The full-thread design provides high tensile and compressive strength across the entire 40 mm length, while the Wirox surface treatment delivers durable corrosion protection for indoor applications. The PZ2 drive ensures reliable control with every drive.
