The ASSY 3.0 SK with a large washer head is especially suitable for staircase construction/woodworking and carpentry. For screw connections in staircase construction, modular construction, timber and passive house construction.

Hardened steel, zinc plated, yellow coated, partial thread, large washer head, AW drive, counter thread

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.

Large washer head

Very high penetration resistance or consolidation

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 3 bit sizes for the diameters 5.0 to 12.0 mm

End mill – the "auxiliary motor" for lower force

Reduction of the screw-in and head countersinking torque by around 20%, especially with long screws

Protection of screw-in tools

From diameter = 5 mm, L = 70 mm

Asymmetric coarse thread – faster speed

Low screw-in torque

High over-turning force

Faster screwing than conventional chipboard screws – reduces processing time by 30%

Tip

Very precise positioning thanks to the 34° tip

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

Notice

Do not use the screw in applications exposed directly to the elements, in humid rooms or in atmospheres containing chlorine gas. For applications outdoors and in rooms which are briefly or constantly subjected to high humidity, please use the stainless steel ASSY 3.0 SK A2 screw, prefix number 0181.

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). When using these screws, please follow ETA-11/0190 specifications.

Hardwood must be pre-drilled in accordance with ETA-11/0190.

Timber dimensioning software, load tables and detailed processing instructions can be found on the service page www.wuerth.de/assy.
