Bolt Set

The Bolt Set (OEM HD612-03612) is a high-quality alternative spare part built for rock drills and drifter rigs working under the toughest mining and tunnelling conditions. It secures and clamps mating components together, maintaining structural integrity and correct preload under continuous vibration and impact loading.

Manufactured from high-tensile, corrosion-resistant steel to precise thread tolerances, it delivers reliable clamping force and resistance to loosening and fatigue. As an alternative replacement, it ensures reliable fit and function while offering significant cost savings over the original.
