The screws are not suitable for outdoor use or for spaces subject to short-term or continuous high moisture levels! Please use ASSY® 3.0 A2 stainless steel screws in these cases.
ASSY 3.0 chipboard 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 (e.g., drill bit, counterthread, ring thread, serrated edge, self-clearing groove). These include screws designed for plastic dowels, DIN 571 compliant hexagon wood screws, and Wüpofast screws.
