Nickel-plated steel, full thread, raised countersunk, 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
- Single, double or coarse thread
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/mating 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 or the scraping effect of the counter thread largely prevents blow-outs
- Ring thread: up to 4.5 mm
- Counter thread: from 5.0 mm
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.
The nickel-plated surface coating is only suitable for decorative purposes = no corrosion protection!
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).

Timber dimensioning software, load tables and detailed processing instructions can be found on the service page www.wuerth.de/assy.
For coniferous wood or wood-based materials made from softwood, make the fitting without a bradawl. To reduce the edge distances make a predrilled hole according to the core diameter.
When screwing into hardwood, drill according to ETA-11/0190.
