Stainless steel A2, partial thread, vertical milling pocket head, AW drive



Connects the wood instead of splitting it



Milling pockets – countersink anywhere!


  • Suitable for wood and fittings

  • Minimum damage to coated wood materials

  • Less chips on the surface


End mill – 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 single-start thread – faster speed, higher tensile strength


  • Low screw-in torque

  • High over-turning force

  • Faster screwing in than conventional chipboard screws

  • Coarse thread: 5.0-12.0 mm


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

  • Mating thread: 5.0-12.0 mm


Material:


Corrosion-resistant, austenitic stainless steel (1.4301; 1.4567)

Notice

Pre-drilling to the core diameter in solid hard woods



ASSY 3.0 A2 are resistant to acid to a limited extent and are not suitable for use in atmospheres containing chlorine gas. Use Würth timber construction software to measure ASSY screws with a diameter of more than 5 mm.



To attach metals to wood, machine a precise cut-out in the metal tab.



ASSY 3.0 chipboard screws are optimised for use in wooden materials. Use in plastic anchors may cause a reduction in the load-bearing capacity. 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 number 0151 (countersunk head) and prefix 0153 (pan head).



The range of applications of the various stainless steels is detailed in the following table issued by the ISER (German Information Office for Rustproof Stainless Steel, Non-Rusting Steels for Various Environmental Conditions, www.edelstahl-rostfrei.de, Information Sheet 828). Rustproof stainless steels (e.g. material no. 1.4016) are recommended in terms of atmospheric conditions only for use in a rural environment, and in this respect only subject to significant restrictions. We therefore recommend only using austenitic stainless steels for outdoor applications, taking the environmental conditions into account. Stainless steel A4 is especially suitable for use in an industrial atmosphere and for use near the sea.
