Zinc-plated steel, blue passivated, partial thread, countersunk milling pocket head, AW drive
Connects the wood instead of splitting it
Surfaces:
Solid wood (coniferous wood, ash, beech, oak), laminated beams, cross-laminated timber (CLT), laminated veneer lumber (coniferous wood or BauBuche), OSB and chipboard.
Milling pockets - countersink anywhere
- Suitable for wood and fittings
 - Minimum damage to coated wood materials
 - Less chips on the surface
 
Milling shank: the "auxiliary motor" for lower force
- Reduction of the screw-in and head countersinking torque, especially with long screws
 - Protection of screw-in tools
 - From diameter = 5 mm, L = 70 mm
 
Asymmetric thread for higher speed
- Low screw-in torque
 - High over-turning force
 - Faster screwing in than conventional chipboard screws
 - Double thread: 3.0-4.5 mm
 - Coarse thread: 5.0-12.0 mm
 
AW drive for more power
- Optimal power transmission
 - Very good snug fit
 - Fast location
 - Screw locates securely
 - Almost no cam-out 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 for 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: 3.0-4.5 mm
 - Mating thread: 5.0-12.0 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.
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).

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.
