SPAX Wirox 8000000287190 Universal Screw, 3.5 x 20 mm, Pack of 360, Fully Threaded, Countersunk Head, T Star Plus T20, 4CUT,

High-quality coating: the Wirox A9J surface is chrome (VI) free and offers high corrosion protection - harder and more durable than conventional zinc plating for long-lasting connections inside and outside Effortless screwing: the thread with serrated edge and special 4CUT tip allows easy processing without pre-drilling, reduces effort and extends battery life Perfect bit fit: the T-Star plus T20 force grip with guide pins fixes the bit securely in the screw - prevents slipping and allows precise, controlled screwing, even overhead Maximum stability: the full thread dissipates tensile and compressive forces over the entire screw length - the multi-countersunk head sinks flush into the wood and protects metal fittings from damage Reliable quality: SPAX screws with Wirox coating are manufactured in Germany – precise workmanship for stable wood connections indoors and protected outdoor areas
