Key Features

• Genuine OEM Fastener Integrity — Manufactured to Multiquip's exact thread pitch, grade, and dimensional spec, ensuring correct clamping load without risk of stripping or under-torquing.
• Integrated Lock Washer Design — The lock washer is paired with the bolt as a single assembly, preventing loosening under the continuous vibration loads common in diesel generator operation.
• Broad DCA-Series Compatibility — Confirmed fit for DCA40SSAI, DCA45SSIU2, DCA60SSAI, DCA60SSI2, DCA40SSI, DCA45SSIU2-FEMA, and DCA45SSIU2-GEER ultra-silent generator models.
• Direct Service Replacement — Drops into existing mounting positions with no rework, making it straightforward to swap during routine servicing or after hardware damage in the field.
• Electrical Safety Assurance — Using the correct OEM-grade hardware on generator enclosures and internal mounts helps maintain proper bonding and grounding continuity critical to safe generator operation.

Bolts and lock washers in a diesel generator serve as the primary mechanical fasteners holding enclosure panels, mounting brackets, and internal components in place under constant engine vibration. The lock washer component applies spring tension against the bolt head and mating surface, resisting the loosening that vibration would otherwise cause over time. When fasteners back out or fail, panels and components can shift, creating misalignment, noise, and in critical mounting locations, potential safety hazards — making correct, OEM-specified replacement hardware essential during any generator service.
