Create solid wood joints without gap formation using this Spax chipboard screw. Thanks to the partial thread, you pull timber boards or battens tightly against your substructure, making it ideal for indoor furniture assembly and interior fittings. The t-star plus T20 drive eliminates bit slippage and guarantees direct torque transfer. With its countersunk multi-head, the screw sinks cleanly and flush into the timber surface without splitting the wood or requiring pre-drilling. In addition, the Wirox coating provides significantly higher corrosion protection than standard galvanized steel for dry indoor and sheltered applications. Supplied in a box of 1000 pieces in 4.5 x 30 mm, you have everything needed to work efficiently.
