Multiquip 0012112040 Hex Head Bolt

The Multiquip 0012112040 is a genuine OEM Hex Head Bolt designed for the DCA Super-Silent and Ultra-Silent series diesel generators, including DCA180SSJU4F3, DCA220SSJU4F, DCA300SSJU4F, and a wide range of related DCA-series models. As a factory-original component, it is manufactured to the exact material grade, thread pitch, and dimensional tolerances required by Multiquip engineering. This bolt is a direct OEM replacement, meaning it installs without any modification to match the original hardware position on your generator. DHS Equipment stocks this part to keep your DCA-series generator running with the correct fasteners in every critical assembly point.

Key Features

• OEM Material and Thread Specification — Manufactured to the exact grade, thread pitch, and head geometry specified for DCA-series generator assemblies, ensuring proper torque load and secure clamping across critical joints.
• Drop-In Hardware Replacement — Matches the original bolt dimensions precisely, seating correctly in existing mounting points and threaded holes without rework or re-drilling.
• Broad DCA-Series Compatibility — Fits a wide range of Super-Silent diesel generator models including DCA180SSJU4F3, DCA220SSJU4F, DCA300SSJU4F, DCA400SSK, DCA600SSK, DCA800SSK, and many additional DCA variants.
• Structural Integrity Under Load — A correctly specified bolt maintains clamping force on generator enclosure panels, engine mounts, and accessory brackets; an incorrect or worn fastener can lead to loosening, vibration damage, or component misalignment during operation.
• Genuine Multiquip OEM Part — Sourced directly from Multiquip, this is not an approximated substitute — it carries the correct part number 0012112040 for verified fitment on your machine.

A hex head bolt may seem like a simple fastener, but in generator applications it plays a direct role in holding together critical structural and mechanical assemblies — from engine mounting and enclosure panels to bracket and frame connections. When bolts are under-spec, corroded, or incorrect for the application, they can fail to maintain proper clamping load, leading to vibration-induced loosening or component movement that causes accelerated wear elsewhere in the machine. Using the correct OEM fastener ensures that torque specifications can be met during service and that the joint behaves as the original design intended throughout the generator's service life.
