Not suitable for near the sea

The expansion bolt Fischer FBN 2 is made of zinc plated steel. Consequently, it is not suitable for bolting near the sea. This is because this steel quality does not have anywhere near the required corrosion resistance.

For use near the sea, we recommend the bolts and lugs from Fixe Climbing. The Fixe PLX – Duplex steel has the corresponding features such as a two-phase structure and resistance to pitting and stress corrosion cracking.

The HCR steel parts from Climbing Technology have an even higher corrosion resistance. You can find HCR expansion bolt and HCR bolt hanger in our store.
