The Raumer bolt hanger Rock 12mm is a classic hanger. It is made of AISI 316L steel (A4 steel). It can therefore be used anywhere in the Alps. It is best mounted with 12mm A4 steel expansion bolt to prevent galvanic corrosion. Like all Raumer products, this bracket is simply passivated. This means that the protective outer layer has been further strengthened by an acid bath.
The strap complies with the EN 959 standard. This makes it a suitable choice for official climbing areas and climbing frame holders.
In short: this flap is a good choice!

Avoid galvanic corrosion with Raumer bolt hanger Rock 12mm
Only A4 steel quick links may be screwed into the Raumer bolt hanger. Zinc plated screw links lead to galvanic corrosion of the base metal. Therefore, make sure you use the correct steel quality when fitting the links.

Not suitable for bolting near the sea!
The Raumer bolt hanger Rock 12mm is not suitable for bolting near the sea. The AISI 316L steel does not meet the required corrosion class. In order to withstand the extreme chemical conditions in the medium to long term, products made of duplex steel are required as a minimum.
Perfect for bolting near the sea:
- glue in bolt made of titanium
- glue in bolt made of HCR steel
- injection mortar for use near the sea
