ASSY^® 3.0 SK timber screw

Hardened steel, zinc-plated, blue passivated, partial thread, large washer head, AW drive, mating thread

Connects the wood instead of splitting it

Substrates:

Solid wood (coniferous wood, ash, beech, oak), laminated beams, cross laminated timber (CLT), timber veneer (coniferous wood or BauBuche), OSB and chipboard.

Large washer head

• Very high penetration resistance or consolidation

AW drive – more power

• Optimum transmission of forces


• 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 3 bit sizes for the diameters 5.0 to 12.0 mm

End mill – the "auxiliary motor" for lower force

• Reduction of the screw-in and head countersinking torque by around 20%, especially with long screws


• Protection of screw-in tools


• From diameter = 5 mm, L = 70 mm

Asymmetric coarse thread – faster speed

• Low screw-in torque


• High over-turning force


• Faster screwing than conventional chipboard screws – reduces processing time by 30%

Tip

• Very precise positioning thanks to the 34° tip

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
