Galvanised steel, blue coated, full thread, countersunk head, AW drive
Joins wood instead of splitting it
Asymmetrical thread – greater speed
- Low screw-in torque
- High over-turning force
- Faster screwing than conventional particle board screws
- Double thread: 3.0–4.5 mm
AW drive — more power
- Optimal force transmission
- Excellent fit
- Rapid finding
- Screw settles securely
- Virtually no unscrewing of bit
- No wobbling
- No damage to surface coating of screw
- Only 5 bit sizes for diameters 3.0 to 12.0 mm
Ring thread — less tendency of the wood to split, very few blow-outs
- Low splitting forces, in particular when screwing close to edges
- Reduction of screw-in torque
- Punch effect of ring thread largely prevents 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 bit, mating thread, ring thread, serrated edge, self-clearing groove, etc.) in plastic dowels, e.g. Würth ASSY D, prefix 0151 (countersunk head) and prefix 0153 (pan head).
