Art.122 - HANG FIX stainless steel bolt M8L – Ø8x78 



Stainless steel AISI 316L bolt, long type (M8x78).

Ideal for caving or cave rescue use.

Features two expanding collars, making it particularly suited for anchors in hard limestone.

Not suitable for use on soft rock such as sandstone or too hard (such as quartzite, granite) or for climbing anchors.

In the M8 bolts, the classic nut and washer have been replaced with a single M8 flanged nut thus negating the laborious use of the small and easily-lost washer.

This allows the plate to be well tightened on a larger surface area.

In addition, this almost eliminates the natural loosening of the nut.

Note: The article can be supplied with the previous model’s classic nut and washer on request and at no additional cost.


New type

The expanding collar is a new design and has greatly improved on the previous version.

The design phase focused on creating a technology which ensures expansion on an increased number of surfaces.

Our tests show that this objective has been achieved.

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.


Technical Specifications

The material used in the majority of our anchors is now stainless steel AISI 316L, which offers a higher resistance to marine corrosion than the former AISI 304.

To highlight this change each article is stamped with the relevant symbols.

However, certain bolts have not been branded as once in place, the symbols would be invisible.

On bolts however, this would be invisible once the bolts have been placed so instead a small circular collar has been added (see photo below) to mark the difference between the two metals.

This allows verification of the type of bolt used at any time.
