Zinc-plated steel, yellow, partial thread, countersunk milling pocket head, AW drive
Connects the wood instead of splitting it
Milling pockets – countersink anywhere!
End mill – the "auxiliary motor" for lower force
Asymmetric thread – faster speed
AW drive — more power
Ring/mating thread — less tendency of the wood to split, very few blow-outs
The screws are not suitable for outdoor use and for rooms subject to short-term or continuous high moisture levels! Please use ASSY® 3.0 A2 stainless steel screws in these cases.
To attach metals to wood, machine a precise cutout in the metal tab.
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 (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).
