Stainless steel A2, full thread, 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

  • Double thread: 3.0–4.5 mm

  • Coarse thread: 5.0–12.0 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: 3.0–4.5 mm

  • 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



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. Plug screws, DIN 571 hexagon wood screws or Wüpofast screws.



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.
