With the Spax chipboard screw, you achieve strong and gapless timber joints for interior framing, cabinetry, and furniture assembly. Thanks to the partial thread, it pulls wooden beams, battens, mdf, and chipboard panels tightly together. The countersunk multi head sinks flush into the wood surface without splintering the material. Featuring a t-star plus T20 drive, it ensures optimal torque transmission and prevents bit slippage for smooth, controlled driving. Furthermore, the Wirox coating provides significantly better corrosion protection on the steel than standard zinc plating. This pack of 200 screws measuring 4.5 x 80 mm gives you the dependable fastening power you need for indoor timber projects.
