All versions

Specification

For universal use in furniture construction, shopfitting, interior fitting, roofing and carpentry applications

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

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 areaScrewing of wood-wood or steel-wood connections in furniture construction, shopfitting, interior fittings, roofing and timber construction.

Instructions

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.
