Connects the wood instead of splitting it!
Milling pockets — countersink anywhere
- Suitable for wood and fittings
- Minimum damage to coated wood materials
- Less chips on the surface
Asymmetric thread — faster speed
- Low screw-in torque
- High over-turning force
- Faster screwing in than conventional chipboard screws
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/mating 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
- 3.0–4.5 mm diameter = ring thread
- 5.0–12.0 mm diameter = mating thread
Head access hole
Suitable for cover caps with 2.5 mm stud diameter
The screws are not suitable for outdoor use and for rooms subject to short-term or continuously high moisture levels! Please use ASSY 3.0 A2 stainless steel screws in these cases. The surface coatings of nickel and brass are suitable for decorative purposes only = no corrosion protection!
ASSY 3.0 chipboard screws are optimised for use in wooden materials. Use in plastic anchors 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 anchors, e.g. Würth ASSY D, prefix number 0151 (countersunk head) and prefix number 0153 (pan head).

When using these screws, the ETA-11/0190 specifications must be observed.
