Proof of Performance

ETA-11/0190

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.

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.

The range of applications of the various stainless steels is detailed in the following table issued by the ISER (German Information Office for Rustproof Stainless Steel, Non-Rusting Steels for Various Environmental Conditions, www.edelstahl-rostfrei.de, Information Sheet 828). Rustproof stainless steels (e.g. material no. 1.4016) are recommended in terms of atmospheric conditions only for use in a rural environment, and in this respect only subject to significant restrictions. We therefore recommend only using austenitic stainless steels for outdoor applications, taking the environmental conditions into account.
