Raumer HANG FIX inox M8L (M8x78mm)

 HANG FIX stainless steel bolt M8L – Ø8x78 expansion bolt

  • 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 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) to mark the difference between the two metals.
  • This allows verification of the type of bolt used at any time.


  • Extraction R = 20 KN
