With the Spax s chipboard screw, you achieve strong and neat wood joints in furniture making, cabinetry, and board materials such as chipboard, OSB, or MDF. The countersinking multi-head seats flush into timber without damaging the surface, ensuring a smooth and clean finish every time. Thanks to the PZ2 cross recess drive, your bit stays securely positioned to prevent cam-out while driving. The full thread across 21 mm delivers maximum pull-out resistance in thin panels and hardware fittings. Additionally, the Wirox coating provides long-lasting corrosion protection on the steel, keeping your interior timber fastenings solid and dependable.
