Lock Nut

Intended for equipment that operates under repeated load, vibration and contamination exposure, the Lock Nut (OEM 4350 2650 89) supports the rock drilling machine assembly. The part provides a defined fastening or locating function, supporting secure assembly and controlled clearance at the joint.

As an aftermarket alternative, it supports practical spare-parts planning and helps reduce dependence on a single supply channel. The locating and contact surfaces are intended to maintain consistent fit so connected parts remain securely positioned under changing mechanical loads. Listed compatible equipment includes DHR 6H and DHR 6H-SH. Verify the exact machine variant before installation or ordering.
