Zinc-plated steel, blue passivated, partial thread, countersunk milling pocket head, AW drive



Connects the wood instead of splitting it



Surfaces:


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



Milling pockets - countersink anywhere


  • Suitable for wood and fittings

  • Minimum damage to coated wood materials

  • Less chips on the surface


Milling shank: the "auxiliary motor" for lower force


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

  • Protection of screw-in tools

  • From diameter = 5 mm, L = 70 mm


Asymmetric thread for higher 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 for more power


  • Optimal power transmission

  • Very good snug fit

  • Fast location

  • Screw locates securely

  • Almost no cam-out 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 for 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 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 bit, mating thread, ring thread, serrated edge, self-clearing groove, etc.) in plastic dowels, e.g. Würth ASSY D, prefix 0151 (countersunk head) and prefix 0153 (pan head).
