Galvanised steel, blue coated, full thread, raised countersunk head, AW drive



Joins wood instead of splitting it



Asymmetrical thread – greater speed


  • Low screw-in torque

  • High over-turning force

  • Faster screwing than conventional particle board screws

  • Single thread: up to 4.5 mm

  • Coarse thread: from 5.0 mm


AW drive — more power


  • Optimal force transmission

  • Excellent fit

  • Rapid finding

  • Screw settles securely

  • Virtually no unscrewing of bit

  • No wobbling

  • No damage to surface coating of screw

  • Only 5 bit sizes for diameters 3.0 to 12.0 mm


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


  • Low splitting forces, in particular when screwing close to edges

  • Reduction of screw-in torque

  • Punch effect of ring thread largely prevents blow-outs

  • Ring thread: up to 4.5 mm

  • Counter thread: from 5.0 mm
Notice

The screws are not suitable for outdoor use and for rooms subject to short-term or continuous high moisture levels! Please use ASSY® 3.0 A2 stainless steel screws in these cases.


To attach metals to wood, machine a precise cutout in the metal tab.


ASSY 3.0 chipboard screws are optimised for use in wooden materials. When used in plastic anchors, a reduction of the load-bearing capacity is possible. Therefore, we recommend only using screws without optimised thread tips (drill tip, mating thread, ring thread, serrated edge, self-clearing groove, etc.) in plastic anchors, e.g. Würth ASSY D, prefix 0151 (countersunk head) and prefix 0153 (pan head).
