UniPass Hollow Bolts

Our UniPass Hollow Bolts provide you with a one step bolting solution and the required flexibility when choosing the right support for your mining project.

OPTIMISED BOLT AND DRILL BIT DIAMETERS

With the drill bits welded onto the bolts, you can reduce the diameter of borehole and shorten drilling time. The welded drill bit also reduces the annulus and provides better anchorage capacity and optimises resin consumption.
