With the Spax chipboard screw 3.5x30 mm, you achieve strong and dependable fastening in wood and sheet materials. The full thread delivers excellent grip and high pull-out resistance, making it ideal for furniture assembly, cabinet making, and securing hardware or hinges. Thanks to the PZ2 drive, you drive each screw smoothly with reliable bit engagement and no slipping. The countersunk multi head with ribs sinks cleanly and flush into timber without the need for pre-drilling or pre-countersinking. In addition, the durable Wirox coating provides significantly better corrosion protection than standard zinc-plated steel for all your indoor projects.
