MECHANICAL GALVANISING MZSH
Reliable corrosion protection at a new level.
The innovative mechanical galvanising MZSH was specially developed for fasteners that are exposed to high mechanical stress during assembly.

The advantages of MZSH
- High corrosion protection
- High abrasion resistance
- No risk of hydrogen embrittlement (IHE) during manufacturing
Technical properties
- Coating thickness: 12 - 15 µm
- Corrosion resistance: 720h RR in the salt spray test according to DIN EN ISO 9227
- RoHS compliant
- REACH compliant
- PFAS free
Application examples
The initial reason for developing MZSH was problems of corrosion on slotted clamping pins and spring-loaded lock washers, e.g. tension washers. Below are two corrosion patterns that are repeatedly observed in conventional coating solutions in these areas, despite high corrosion resistances and the correct application of the coating.
MZSH, which was originally developed as a solution for corrosion problems in slotted clamping pin and spring-loaded lock washers can, however, also be used for threaded fasteners. It is also possible to set a friction coefficient µGes of 0.12 – 0.18 in accordance with DIN EN ISO 16047.
We will be happy to advise you for further application possibilities.
