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: PZ 2
• Countersunk head: Screw connections of panels to beams, whenever flush countersinking of the head is required
• Partially threaded: Secure connection with reduced gap formation as the thread does not lock
• 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 edge displaces the fibres of the wood and reduces the screw-in torque
