Mining & Tunneling

For rock bolt application, our anchor nuts are used with a metric thread in conjunction with appropriate anchor plates and threaded steel rods. This allows a power transmission by the ground pressure on the anchor head. Domed nut and retaining nut are used in conjunction with threaded steel anchor with hot rolled, continuous coarse thread

( right hand / left hand ).

The expansion shells are designed to be used for roof support in mining and tunneling areas (underground). Easy to use in conjunction with the corresponding threaded rod with a continuous coarse thread, anchor plate and anchor nut.
