Specification

Ideal for fastening attachments and piano hinges.

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

Joins wood instead of splitting it

Small countersunk head 5.0 mm in diameter

High fitting accuracy

Asymmetric thread — faster speed, high tension resistance

Low screw-in torque

High over-turning force

Faster screwing than conventional particle board screws

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

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

NoticeThe 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. Use Würth timber construction software to measure the ASSY screws with a diameter of more than 5mm. To attach metals to wood, bradawl a precise cutout in the metal tab. ASSY 3.0 particle board 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 (drilling tip, 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 areaIdeal for fastening attachments and piano hinges.

InstructionsScrew-in angle 0° to 90°. 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.
