ASSY 3.0 chipboard screws are optimised for use in wooden materials. Use in plastic anchors may cause a reduction in the load-bearing capacity. Therefore, we recommend only using screws without optimised thread tips (drill 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).
When using these screws, the ETA-11/0190 specifications must be observed.

ETA-11/0190
ASSY HCR 3.0 are made of highly corrosion-resistant steel, material no. 1.4539 (corrosion resistance class IV, Appr. No. Z-30.3-6), and are suitable and approved for use in the following areas:
- 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 fracture corrosion
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.
