Multiquip 0017112055 Hex Head Bolt

The Multiquip 0017112055 Hex Head Bolt is a genuine OEM fastener designed for the DCA-series Ultra-Silent diesel generator lineup, including DCA125, DCA150, DCA180, and DCA220 models. As a direct OEM component, it is manufactured to the exact thread pitch, grade, and dimensional tolerances specified for these generators. Confirmed fitment spans models such as DCA150SSJU3, DCA180SSJU, DCA220SSVU, DCA125SSIU, DCA180SSI, and DCA220SSJ, among others in the DCA Ultra-Silent series. Sourcing the correct OEM bolt ensures structural integrity and proper torque retention within the generator assembly.

Key Features

• OEM-Grade Fastener Specification — Manufactured to the exact thread class, head geometry, and tensile grade called out in the Multiquip parts schema for DCA-series generators, ensuring correct clamp load and torque values are achievable at installation.
• Direct Drop-In Replacement — Matches the original bolt's dimensions and thread engagement length, allowing straightforward installation into existing threaded bosses or clearance holes without rework.
• Broad DCA-Series Fitment — Compatible with DCA125, DCA150, DCA180, and DCA220 Ultra-Silent diesel generator models, covering both 50 Hz and 60 Hz variants across the SSJU, SSIU, SSVU, and SSI configurations.
• Structural Integrity Under Load — A correctly torqued bolt maintains critical joint clamping force in the generator enclosure and drivetrain assembly; a worn, stripped, or incorrect bolt risks vibration-induced loosening and component misalignment during operation.
• Genuine Multiquip Part — Supplied as an authentic OEM component under part number 0017112055, so the bolt meets the same material and heat-treatment standards as the hardware installed at the factory.

A hex head bolt is a threaded fastener used to clamp two or more components together within a mechanical assembly. In diesel generator applications like the DCA Ultra-Silent series, bolts of this type secure panels, mounting brackets, engine ancillaries, and structural frame members — areas where consistent clamping force is essential to manage vibration loads produced during continuous operation. When a bolt is the wrong grade, incorrect thread pitch, or has been stretched beyond its yield point, it can lose clamp load progressively, leading to loosening, component movement, or premature failure of the joined parts. Using the correct OEM-specified replacement, such as the Multiquip 0017112055, ensures the joint performs as engineered for the service life of the equipment.
