Achieve strong and seamless timber joints with the Spax chipboard screws 4.5 x 70 mm. The partial thread with a thread length of 42 mm pulls wooden components and framing tightly together without gaps. Thanks to the t-star plus T20 drive, you benefit from optimal power transmission that prevents bit slippage and cam-out during driving. The countersunk multi-head sinks neatly and flush into the wood surface, while the advanced Wirox coating delivers significantly higher corrosion protection than conventional zinc plating. Supplied in a pack of 500 pieces, this set gives you the reliability needed for all your interior woodwork and timber construction jobs.
