Notice

Hardwood must be pre-drilled in accordance with ETA-11/0190.



ASSY 3.0 chipboard screws are optimised for use in wooden materials. Use in plastic dowels 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 dowels, e.g. Würth ASSY D, prefix number 0151 (countersunk head) and prefix number 0153 (pan head).


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