Set:
Screw: DIN933 A2 M8X90 + wacher: Zn 21,5x8x2,5 + O-ring: NBR70 6,1x1,6

DIN933 A2 M8X90 screws with Zn 21,5x8x2,5 washers and NBR70 6,1x1,6 O-rings can be used in various fields where a strong, corrosion-resistant connection with additional sealing is required.

Construction and structures
- When fastening metal structures outdoors or in damp areas (e.g., roof supports, railings, facade elements).
- Stainless steel A2 class ensures corrosion resistance, making it suitable for use by the sea, in swimming pools, or in industrial premises.

Mechanical assemblies and devices
- When installing device housings, brackets, protective covers, especially where sealing against dust or moisture is required.
- NBR70 O-ring helps ensure tightness between joined surfaces
– often used in pumps, valves, hydraulics.

Water and heating systems
- Suitable for connections where sealing is required
– e.g., for securing water filters, heating manifolds, and valves.
- NBR70 material is resistant to water and oils, making the O-ring suitable for contact with liquids.

Electronics and device enclosures
- If enclosures need to be secured with moisture or dust protection (IP rating), an O-ring helps ensure tightness.
- Stainless steel does not cause electromagnetic interference and does not oxidize.
