SPAX® universal screw, thread ø d1: 4.0 mm, head ø: 8.0 mm, standard packaging

• Thread ø: 4.0 mm
• Head ø: 8.0 mm
• Drive: T20
• Half-round head: Suitable for thin fittings with through hole, lies flat on the material
• 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 galvanised, but no substitute for stainless steel
• Hardened, anti-friction coated
• 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 over heads
