Key Features
- Genuine OEM Material Spec — Manufactured to Multiquip's exact hardness and dimensional tolerances, ensuring proper load distribution across fastened joints in your generator assembly.
- Drop-In Hardware Fit — Matches the original bore diameter, outer diameter, and thickness of the factory washer, seating correctly without modification against the mating fastener and surface.
- Broad DCA-Series Compatibility — Confirmed fitment across DCA25SSI, DCA25SSIU, DCA25SSIU-GEER, DCA25SSAI, DCA25SSI2, DCA40SSI, and DCA40SSAI ultra-silent diesel generator models.
- Protects Mating Surfaces — Distributes clamping force evenly, preventing fastener pull-through and surface damage that can compromise structural and electrical enclosure integrity on long-run generator sets.
- Verified Multiquip Part Number — Part number this part matches Multiquip's official parts documentation, giving you confidence that you are ordering the correct washer for your specific DCA-series unit.
A plain washer serves as a load-spreading interface between a fastener — such as a bolt or nut — and the surface it clamps against. By distributing clamping force over a larger contact area, the washer prevents the fastener head from pulling through or embedding into softer materials and protects finished surfaces from damage during tightening. When a washer is missing, undersized, or deformed, fastener joints can loosen under vibration, leading to rattles, misalignment, or structural loosening in assemblies where secure, consistent clamping is essential to generator enclosure integrity and safe operation.
