Bolt hanger Inox

Our Inox bolt hanger is made of AISI 304L stainless steel. This material is also known as A2 steel. On the one hand, it has a hole for 10mm expansion bolt. And secondly, it is 4mm thick. As a result, there is no bending like with 3mm lugs when a lot of hard falls are made.

With this steel quality, a long service life of 20+ years can be expected in the Alpine region. The corrosion resistance depends on the humidity, temperature and chemical composition of the rock.

When installing the Inox bolt hanger, care should be taken to use suitable expansion bolt. This means that they should also be A2 steel. Under no circumstances should this lug be installed with zinc plated expansion bolt!

Conclusion. This lug is an inexpensive alternative to the more expensive AISI 316L (A4 steel) model. Or to put it another way. If you are looking for maximum stability but have a slightly smaller budget for bolting a climbing route, this is the perfect choice!

To install with A2 steel expansion bolt!

You must install the bolt hanger Inox with A2 steel expansion bolt. This is because they are the equivalent of AISI 304L steel. This means that no galvanic corrosion can occur!

Not familiar with this? Then read our article“Galvanic corrosion at expansion bolt“. There we explain this electrochemical principle in detail. We hope you are careful as developers and help to ensure the safety of the climbing routes.

Bolt hanger Inox = AISI 304L stainless steel

This lug is made of stainless steel a.k.a. Inox. To be precise, this is so-called A2 steel. This is the German designation for this steel grade. The international standard for this is AISI 304 and the “L” indicates a lower carbon version. This material is therefore significantly better than zinc-plated steel. However, it is not quite as corrosion-resistant as AISI 316L (A4), the current standard.
