• Rockbolts and cables

    Tensioning of rockbolts is important to ensure that all of the components are in contact and that a positive force is applied to the rock. In the ca se of light 'safety' bolts, the amount of tension applied is not critical and tightening the nut with a conventional wrench or with a pneumatic torque wrench is adequate.
