Screw

The Screw (OEM 867 643 99) is a durable alternative replacement designed to perform reliably on rock drills and drifter rigs in harsh mining and tunnelling applications. 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. Offered as an aftermarket alternative, it delivers full interchangeability and proven durability at a more competitive cost.
