Key Features
- Genuine OEM Fastener Integrity — Manufactured to Multiquip's exact hardness and dimensional specifications, this Lock Washer delivers the correct clamping force and bite needed to resist loosening under vibration — critical in rotating and engine-driven equipment.
- Drop-In Replacement — Matches the original mounting position and thread engagement on all covered models, installing the same way as the factory-fitted component with no rework required.
- Broad Multiquip Fitment — Compatible with the DLW400ES, DLW300ES, DAC7000SS series diesel generators, and MRH601DS walk-behind roller, covering multiple equipment families with a single part number.
- Vibration Resistance — Lock washers are a front-line defense against fastener back-off caused by engine vibration and operational loading; a worn or missing Lock Washer can allow bolted connections to work loose over time, leading to component shift or damage.
- Electrical and Structural Safety — On welders and generator sets, loose fasteners at grounding points or structural joints can compromise electrical continuity and structural integrity; using the correct OEM Lock Washer maintains those connections as designed.
A Lock Washer is a hardened fastener component placed under a bolt head or nut to prevent rotational loosening caused by vibration, thermal cycling, or dynamic loading. In equipment such as diesel welders, generators, and rollers — all of which generate significant vibration during operation — even a small amount of fastener back-off can allow mounting hardware to shift, creating misalignment, mechanical noise, or electrical grounding issues. Replacing a worn, deformed, or missing Lock Washer with the correct OEM part restores the clamping integrity of the joint and helps prevent more serious fastener failures down the line.
