For applications in utilisation class 1 and utilisation class 2 (from ∅ > 4 mm)
- Five times higher corrosion protection, the zinc-nickel-plated surface chromium(VI)-free 8 µm layer thickness, compared to zinc plated yellow surfaces, 500 h according to the salt spray test according to DIN EN ISO 9227
- For use in utilisation class 1 (interior) and from ∅ > 4 mm in utilisation class 2 (covered outdoor area) according to EN 1995-1-1:2010-12 + DIN SPEC 1052-100:2013-08. The requirement of classification T2/C2 is fulfilled in accordance with prEN 14592:2017 (D)
- Not recommended for use in wood types rich in tannic acids or boiler-pressure impregnated woods in wet areas
- To increase the joining effect or head pull-through resistance, combining with perfectly fitting washers for ASSY 4 is recommended
- ASSY screws are approved for quasi-static loads
- For optimum use of the screw, the right-size RW bit must be used
- Partial-thread screws are ideal for connecting wooden components. To achieve optimum assembly of the components, the components to be fixed must not be thicker than the length of the shank
