Asymmetrical coarse thread

Countersunk head with AW drive

Corrosion-resistant HCR stainless steel (material no. 1.4529)

Notice

Pre-drilling to the core diameter in solid hard woods

ASSY 3.0 chipboard screws are optimised for use in wooden materials. Use in plastic anchors may cause a reduction in the admissible load. Therefore, when using plastic anchors, we recommend only using screws without optimised thread tips (drill tip, mating thread, ring thread, serrated edge, self-clearing groove etc.), such as Würth ASSY D, prefix number 0151 (countersunk head) and prefix number 0153 (pan head).

When using these screws, the ETA-11/0190 specifications must be observed.

ETA-11/0190

Application area

ASSY HCR 3.0 are made of highly corrosion-resistant steel, material no. 1.4529 (corrosion resistance class V, Appr. No. Z-30.3-6, suitable for use in indoor swimming pool areas) and are suitable and approved for use in the following areas:

• Of ceiling and wall coverings in atmospheres containing chlorine, e.g. indoor pools (water conforming to the Drinking Water Ordinance!)
• For components in stables
• In woods with a high tannic acid content
• Particularly good resistance to very aggressive media such as phosphoric acid, sulphuric acid and hydrochloric acid media, high resistance to pitting and stress corrosion cracking

Instructions

Screw-in angle 0° to 90°. For coniferous wood or wood-based materials made from softwood, the screw connection is made without pre-drilling. To reduce the edge distances, a pre-drilled hole can be made according to the core diameter. When screwing into hardwood, pre-drill according to ETA-11/0190.
