A2 stainless steel, full thread, pan head, AW recess
Connects the wood instead of splitting it
Asymmetric single-start thread, faster speed, higher tension resistance
- Low screw-in torque
- High over-turning force
- Faster screwing in than conventional chipboard screws
- Double thread: 3.0 mm to 4.5 mm
- Coarse thread: 5.0-12.0 mm
AW recess for more power
- Optimal power transmission
- Excellent tight fit
- Quick find
- Screw positions securely
- Almost no cam-out
- No wobbling
- No damage to surface coat of screw
- Only 5 bit sizes for the diameters 3.0 mm 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
- Ring thread: 3.0 mm to 4.5 mm
- Counter thread: 5.0-12.0 mm
Material:
- Corrosion-resistant, austenitic stainless steel (1.4301; 1.4567)
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 engineered wood. Use in plastic fixings may cause a reduction in the admissible load. Therefore, we recommend only using screws without optimised thread tips (drill tip, counter thread, ring thread, serrated edge, self-clearing groove etc.) in plastic fixings, e.g. Würth ASSY D, prefix number 0151 (countersunk head), 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. A4 stainless steel is especially suitable for use in an industrial atmosphere and for use near the sea.

Timber dimensioning software, load tables and detailed processing instructions can be found on the service page www.wuerth.de/assy.
The ASSY 3.0 A2 made from corrosion-resistant, austenitic stainless steel is designed especially for applications outdoors, in damp rooms and in salty atmospheres
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.
