As THE specialist for bolting hardware, we naturally also have the right hooks for soft rock, such as our sandstone Bühler bolt.
This is a solid glue in bolt without a load-bearing weld seam. It consists of 14mm thick steel wire and produces a shaft of 15 x 28mm.
Due to its large dimensions, it is also perfectly suited for the most extreme loads in hard rock, such as the attachment of summit crosses, zip lines, small steel cable bridges and the like.
The high-quality AISI 316L stainless steel is treated with our LONGLIFE treatment. This means a double passivation for extra strong corrosion protection!
