FRICTION BOLT

Roof bolts are manufactured from hot-rolled, deformed bar, featuring a rib pattern that ensures better adhesion when fixed with chemical anchors.

Has physical characteristics to maximise loads, transfer from the rock to the bolt, with higher transverse ribs, together with lower profile longitudinal ribs.

Rolled thread nominally equals the column strength of the bar. Available in spin-to-stal (shear pin nut) or reverse spin (nibbed) configurations.

  • Bolts are manufactured to clients’ requirements
