BX HIGHER STRENGTH STEEL ROOF BOLT

The use of specially designed bolt pattern results in a bolt that exhibits optimum load transfer characteristics in both organic and inorganic grouts.

Together with the torque nut, supplied as standard, it represents state of the art technology in the one step installation of roof bolts for mining, tunneling and strata reinforcement.

The optional "pin nut" provides a low drag system, with the added benefit of eliminating the loss of nuts in transit. Special grade roll pins can be changed in the break-out nut to create greater breakout torque if required.
