The ASSY 3.0 SK A2 with a large washer head and partial thread is specially designed for screwing two joined components outdoors and in wet rooms.

A2 stainless steel, partial thread, large washer head, AW drive, ring thread in tip area


  • Connects the wood instead of splitting it


Large washer head


  • High penetration resistance/high consolidation effect.


AW drive - more power


  • Optimal power transmission

  • Very good snug fit

  • Fast location

  • Screw locates securely

  • Almost no cam-out of the bit

  • No wobbling


Asymmetrical single thread - faster speed


  • Low screw-in torque extends the service life of the processing machine and the bit insert

  • High over-turning force

  • Faster screwing in than conventional chipboard screws


Tip


  • Very precise positioning thanks to the 30° tip.


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


  • Minimal splitting forces, especially when screwing in at edges

  • Blow-outs are avoided to a high degree thanks to the punching effect of the ring thread


Material:


  • Corrosion-resistant, austenitic A2 stainless steel (1.4301; 1.4567)
Notice

Use Würth timber construction software to measure the ASSY screws with a diameter of more than 5mm. Austenitic stainless steel is characterised by a high degree of corrosion resistance against aggressive industrial air, sea air, tap water, river water, mine water and salt water, as well as woods containing tannic acid. It is resistant to acid to a certain extent and not suitable for atmospheres containing steel-grade chlorine gas.


The range of applications of the various stainless steels is contained in the following ISER (German Information Office for Rustproof Stainless Steel, Non-Rusting Steels for Various Environmental Conditions, www.edelstahl-rostfrei.de, Information Sheet 828) table. Rustproof stainless steels (e.g. material no. 1.4016) are recommended there for use in atmospheric processes only for use in a rural environment, and here as well only with great 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. ASSY 3.0 particle board 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 (drilling tip, 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).


When using these screws, please follow ETA-11/0190 specifications.

Application area

Universal use in photovoltaic/timber/carpentry trades for a tight-fitting consolidation of two parts

Instructions

Screw-in angle 0° to 90°. For coniferous wood or wood-based materials made from softwood, make the fitting without a bradawl. To reduce the edge distances make a predrilled hole according to the core diameter. When screwing into hardwood, drill according to ETA-11/0190.
