46mm High strength  rock roofing support split set anchor bolt

Friction bolt (Split sets) is roll formed into a C shape bolt with slot by high tensile steel band,which one end is tapered for easily inserting bolt into drilling hole.The other end is welded a ring to hold the bearing plate. 

Functions

Friction bolt (Split sets) is a frictional ground support system.When friction bolt is inserted into drilling hole with smaller diameter, the slot partially closes and bolt diameter is compressed, which creates radical forces  on rock roof surface along the whole length and firmly holds the rock.
