All versions

Specification

For universal use in furniture construction, shopfitting, fitting attachments and interior fittings.

Galvanised steel, blue coated, full thread, countersunk head, 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

Double thread: 3.0–4.5 mm

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 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 largely prevents blow-outs

Notice

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).

ETA-11/0190

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

Application

Application areaFor universal use in furniture construction, shopfitting, fitting attachments and interior fittings.

InstructionsFor 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.
