For compact and hard wood, pre-drilling is required in compliance with ATE-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 using only screws without optimised thread tips (drill tip, mating thread, ring thread, serrated edge, self-clearing groove etc.) in plastic fixings, e.g. Würth ASSY D, prefix number 0151 (countersunk head) and prefix number 0153 (pan head).
When using these screws, please follow ETA-11/0190 specifications.
ETA-11/0190
For mounting slate on roofs, tricky walls and large surfaces.
Direct mounting through holes present in the slate (from bottom to top) without additional materials.
