Description

The DSI Friction Bolt is manufactured from high strength steel tube which has a slot along its entire length. A ring, or collar, is welded on the outer end to hold a domed plate to the rock surface.
The 33mm & 39mm Friction Bolt is suitable for installation with hand held rock drills (stopers/drifters). The 46mm Friction Bolt is NOT suitable for installation with hand held rock drills (stopers/drifters).
Friction bolts can be load tested by fitting a special ring to the bolt prior to its installation. Pull tests can then be conducted with a hollow ram hydraulic jack.
