With Spax 5 x 30 mm screws, you create strong, dependable joints in timber and sheet materials such as mdf or chipboard with ease. The full-thread design provides high pull-out resistance, making it ideal for cabinetmaking and securing metal fittings, brackets, or hinges. Thanks to the t-star plus T20 drive recess, your bit sits firmly in place without slipping or camming out during driving. The countersunk multihead recesses cleanly into the wood to deliver a smooth, flush finish. In addition, the durable Wirox coating offers significantly higher corrosion protection than standard zinc plating for all your indoor fastening tasks.
