Connects the wood instead of splitting it
Asymmetric thread – faster speed
- Low screw-in torque
- High over-turning force
- Faster screwing in than conventional chipboard screws
- Single-flight thread
AW drive – more power
- Optimum transmission of forces
- Very good snug fit
- Fast location
- Screw locates securely
- Almost no unscrewing of the bit
- No wobbling
- No damage to surface coating of screw
- Only 5 bit sizes for the diameters 3.0 to 12.0 mm
Ring thread – less tendency of the wood to split, very few blow-outs
- Minimal splitting forces, especially when screwing in at edges
- Reduction of the screw-in torque
- Blow-outs are avoided to a high degree thanks to the punching effect of the ring thread
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.
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).
To attach metals to wood, machine a precise cutout in the metal tab.

When using these screws, please follow ETA-11/0190 specifications.
Securing thin sheet metal onto wood in shopfitting, interior fitting and furniture construction.
Screw-in angle 0° to 90°. For coniferous wood or wood-based materials made from softwood, the screw connection is made without pre-drilling. To reduce the edge distances, a pre-drilled hole can be made according to the core diameter. When screwing into hardwood, pre-drill according to ETA-11/0190.
