Retaining Screw

The Retaining Screw (OEM 550 267 52) is a precision-made alternative spare part for rock drills and drifter equipment used in the most challenging mining and tunnelling environments. It secures and clamps mating components together, maintaining structural integrity and correct preload under continuous vibration and impact loading.
