Dome Ball Rock Bolts-Bolt fittings

Hot forged dome ball washer to suit M24 rock bolts

Key Features

The use of a Dome Ball, with compatible Domed Plate, generally ensures better alignment of the bolt to the roof and together will maximise load transfer from the bolt to the surrounding rock.
Without the use of the Dome Ball, bending of the bolt at the collar can occur causing local abnormal loading of the bolt and potential early failure.
Similarly, without the use of a Dome Ball thread, binding can be a problem during installation, limiting the tensioning of the bolt.
The Dome Ball is suitable for angles of tilt up to 18° with a compatible plate.
Corrosion protection may be provided by hot dip galvanizing.
