Stainless steel AISI 316L bolt, ideal for use in climbing and mountaineering anchors.
Attention: On particularly soft rocks (such as sandstone) all expansion bolts - including our own - are not recommended due to the unreliable nature of the supporting material.
In these circumstances we recommend the use of fixed resin anchors (epoxy glue resin) or Multi-Monti screw anchors.
The majority of our anchors are made with stainless steel AISI 316L, which offers a higher resistance to marine corrosion than the former AISI 304.
To highlight this difference each article is stamped with the relevant symbols.
However bolts have not been branded as once in place, the symbols would be invisible, so instead a small circular collar has been added (see photo above) to mark the difference between the two metals.
This allows verification of the type of bolt used at any time.
There is also a "Marina” version of this anchor which is highly resistant to saline corrosion.
To mark the difference between stainless steel AISI 316L and the marina version of the same material, all marine-suitable anchors have been marked with a fish symbol and the initials “INOX".
Note: As mentioned above, this branding is not used on bolts. In order to differentiate the marine version, as well as the afore-mentioned collar there is a small engraved dimple which allows for accurate identification once the bolt is in place (See photo above).
We recommend reading the attached PDF document for a detailed explanation of the problems presented by marine corrosion.
