Brass plated steel, full thread, raised countersunk head, AW recess
Connects the wood instead of splitting it
Asymmetrical thread for increased speed
- Low screw-in torque
- High over-turning force
- Faster screwing in than conventional chipboard screws
- Double thread: 3.0-4.5 mm
AW recess for more power
- Optimal power transmission
- Excellent tight fit
- Quick find
- Secure screw positioning
- Almost no cam-out
- No wobbling
- No damage to surface coat 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
- 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
- Ring thread: up to 4.5 mm
The brass plated surface coat is only suitable for decorative purposes = no corrosion protection!
The screws are not suitable for outdoor use or for rooms subject to short-term or continuously high humidity levels! Please use ASSY 3.0 A2 stainless steel screws in these cases.
To attach metals to wood, machine a precise cut-out in the metal tab.
ASSY 3.0 chipboard screws are optimised for use in engineered wood. Use in plastic anchors may cause a reduction in the admissible load. Therefore, we recommend only using screws without optimised thread tips (drill tip, counter 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).

ETA-11/0190
When using these screws, the ETA-11/0190 specifications must be observed.For softwood or engineered wood 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.
