Zinc-plated steel, yellow, partial thread, countersunk milling pocket head, AW drive
Connects the wood instead of splitting it
Substrates:
Solid wood (coniferous wood, ash, beech, oak), laminated beams, cross laminated timber (CLT), timber veneer (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
End mill – 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 – faster speed
- Low screw-in torque
- High over-turning force
- Faster screwing in than conventional particle board screws
- Double thread: 3.0–4.5 mm
- Coarse thread: 5.0-12.0 mm
AW drive — more power
- Optimum transmission of forces
- Excellent 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
- 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 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).
