With Spax s screws, you can create strong and dependable timber connections with ease. The partial thread design firmly draws wooden components, framing battens, and chipboard or mdf panels tight against substructures for a seamless fit. Featuring a countersunk multi-head, each screw neatly countersinks flush into the wood surface without splintering or the need for pre-countersinking. The PZ2 drive ensures positive bit engagement and smooth torque transfer. In addition, the advanced Wirox coating delivers significantly higher corrosion resistance than conventional zinc plating for all your indoor fitting and covered timber projects.
