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

  • Single-flight thread


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 5 bit sizes for the diameters 3.0 to 12.0 mm


Ring 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
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.



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 dowels, e.g. Würth ASSY D, prefix number 0151 (countersunk head) and prefix number 0153 (pan head).



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