The Multiquip 0012120055 is a genuine OEM Hex Head Bolt designed for the DCA-series super-silent and ultra-silent diesel generator lineup, including the DCA500SSK, DCA600SSK, DCA600SSV, and DCA600SSV4F3 variants. As a factory-sourced fastener, it meets the exact torque ratings, thread pitch, and material grade specified by Multiquip for these units. Sourcing the correct OEM bolt ensures structural integrity at the point of installation — whether securing panels, internal assemblies, or engine-adjacent components. DHS Equipment stocks this part to keep your DCA-series generator running without unnecessary delays.
Key Features
- OEM-Grade Fastener Specification — Manufactured to the exact thread pitch, head geometry, and tensile strength required by Multiquip for DCA-series generators, ensuring a secure, load-bearing connection.
- Direct-Fit Replacement — Matches the original bolt position and hardware spec on DCA500SSK, DCA600SSK, DCA600SSV, DCA600SSV4F3B, DCA600SSV4F3PB, and DCA600SSK-GEER units without rework or adaptation.
- Broad DCA-Series Compatibility — Covers multiple configurations across the super-silent generator family, including Tier 4 Final variants such as the DCA600SSV4F3B and DCA600SSV4F3PB.
- Structural Connection Integrity — A properly torqued OEM bolt maintains tight assemblies under generator vibration and load cycling; an incorrect or worn fastener risks loosening over time, leading to component shift or damage.
- Genuine Multiquip OEM Part — Supplied directly through the Multiquip parts network, so the grade, finish, and dimensions are consistent with what the machine was built with at the factory.
A hex head bolt is a fundamental structural fastener that clamps two or more components together and holds them in position under tension. In a diesel generator like the DCA-series, fasteners are subjected to continuous vibration from the engine and alternator, making correct thread engagement and proper torque critical to long-term assembly stability. Using an incorrect or substandard bolt — one with the wrong thread pitch, shank length, or material grade — can result in improper clamping force, fastener fatigue, or eventual failure of the joint it secures.
