With Spax chipboard screws 4.5x45 mm, you create strong and dependable connections in wood and sheet materials. The full thread delivers high pull-out resistance and a secure hold in chipboard, MDF, and solid timber. Thanks to the countersunk multihead, the screw sinks flush and clean into the surface without splitting the wood fibers, while braking cleanly against metal fittings. The PZ2 Pozidriv recess ensures excellent torque transfer and prevents slipping during driving. In addition, the innovative Wirox coating provides significantly higher corrosion resistance than standard zinc plating. With this 500-piece pack, you are perfectly equipped for interior fitting and furniture assembly.
