The Locking Screw (OEM 150 693 88) is a premium aftermarket replacement engineered for rock drilling and drifter rigs operating in the most demanding mining and tunnelling environments. 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 spare part, it offers full functional interchangeability at a competitive cost, without compromising performance or reliability.
