ASSY^® 3.0 zinc-plated yellow chipboard screw

Galvanised steel, yellow, full thread, raised countersunk head, AW drive

Connects the wood instead of splitting it

Asymmetric thread – faster speed

• Low screw-in torque


• High over-turning force


• Faster screwing in than conventional chipboard screws


• Double thread: 3.0–4.5 mm


• Coarse thread: 5.0-12.0 mm

AW drive – more power

• Optimum power transmission


• Very good snug fit


• Fast location


• Screw locates securely


• Almost no unscrewing of the bit


• No wobbling


• No damage to surface coating of screw


• Only 5 bit sizes for the diameters 3.0 to 12.0 mm

Ring/mating thread — less tendency of the wood to split, very few blow-outs

• Minimal splitting forces, especially when screwing in at edges


• Reduction of the screw-in torque


• Blow-outs are avoided to a high degree thanks to the punching effect of the ring thread


• Ring thread: 3.0–4.5 mm


• Mating thread: 5.0–12.0
