Countersunk head screw SPAX® WIROX® full thread T - STAR Plus ø 4.0 x 40 mm, PU 1000 pieces

• Thread ø: 4.0 mm
• Head ø: 8.0 mm
• Drive: T20
• Countersunk head: Screw connections of panels to beams, whenever flush countersinking of the head is required
• Fully threaded: Screw connection of fittings with through hole, absorption of high tensile forces, high contact pressure
• Electrogalvanised (WIROX®): For indoor and outdoor applications without direct weathering, 20 times higher corrosion protection than standard galvanising, but no substitute for stainless steel
• Hardened, anti-friction coated
• MULTI head, cuts through wood - brakes on metal
• 4CUT tip: Without pre-drilling (depending on the wood), effectively reduces the splitting effect. Square point displaces the fibres of the wood and reduces the screw-in torque
• T-Star® plus: Clean fit of the Bits and better guidance, e.g. when working overhead
