Key Features
- Genuine OEM Hardness and Temper: — Manufactured to Multiquip's specified spring hardness grade, ensuring the washer maintains correct locking tension under torque without deforming or cracking.
- 6MM Bore Compatibility: — Sized precisely for 6MM fastener shafts, seating flush against mating surfaces for consistent clamping load across bolt connections.
- Verified Fitment: — Confirmed for use on DM15A9C and CDM2CSA series machines, eliminating guesswork when sourcing fastener hardware during service or assembly.
- Vibration Resistance: — The split-ring design bites into the fastener and mating surface under load, resisting loosening caused by operational vibration common in drilling and core equipment.
- Direct OEM Replacement: — Matches the original part in profile, finish, and material grade, installing identically to the factory component with no fitting adjustments needed.
A lock washer is a hardened fastening component placed beneath a bolt or nut to prevent the fastener from backing out due to vibration, torque cycling, or dynamic load. The split-ring design works by compressing under bolt load, creating a spring-like tension that keeps the fastener seated even as the machine operates. When a lock washer is worn, deformed, or missing, fastener connections can gradually loosen, leading to mechanical play, misalignment, or component separation — particularly problematic in drilling equipment where precision and rigidity are critical to safe, accurate operation.
