Raumer Hang-Fix M10XL
Stainless (AISI 316L) caving anchor of the 'through bolt' variety, M10 x 110
Redesigned and improved double expanding collars increase security, making it very suitable for setting anchors for pitches, where the rock is compact and solid (where the medium is poor then resin anchors are preferred.
Requires a drill, or Rocpec type hand drill, to place it. A very good bit is probably the Hilti four tip; 120mm long is just right and avoids over drilling - which wastes battery life
Strengths given, 21kN in traction and 26kN in radial load.
