The main application of the OMEGA-BOLT® Expandable Friction Bolt is temporary rock reinforcement in Mining and Tunneling. Bonding forces between the friction bolt and the rock mass are caused by form closure and friction transfer between the borehole wall and the rock bolt which is expanded by hydraulic pressure. The DSI OMEGA-BOLT® is an expandable rock bolt with excellent elongation properties designed to accommodate ground movement. The OMEGA-BOLT® is a folded steel tube with welded bushings on each end.
