Multiquip 0010120050 Hex Head Bolt

The Multiquip 0010120050 is a genuine OEM Hex Head Bolt designed for the DCA Ultra-Silent and Super-Silent diesel generator series, including models DCA125SSIU4F, DCA125SSJU4I, DCA125USI3CAN, DCA125USJ, DCA150SSJU4F, DCA220SSJ. As a direct OEM replacement, this bolt is manufactured to the exact specifications required to maintain the structural and mechanical integrity of your generator. Sourced directly from Multiquip, this part ensures a correct, no-compromise installation across the full range of compatible DCA and NGA platforms.

Key Features

• OEM-Grade Fastener Integrity — Manufactured to Multiquip's exact thread pitch, diameter, and tensile strength specifications for critical generator assembly points.
• Drop-In Replacement — Engineered to install in the same position and orientation as the original bolt, with no reworking of mounting surfaces or hardware required.
• Broad DCA and NGA Series Compatibility — Fits a wide range of Ultra-Silent and Super-Silent generator models including DCA70USI, DCA125SSIU4F, DCA220SSJU4F, DCA400SSI, and more.
• Structural Clamping Performance — Correct torque capacity ensures components remain properly seated under load, vibration, and extended run cycles typical of generator operation.
• Fuel and Electrical System Safety — Used in fastening applications where improper hardware can compromise fuel line, enclosure, or electrical component security — using the correct OEM bolt matters.

A hex head bolt may seem straightforward, but in generator applications, fastener grade and dimensional accuracy are critical. The wrong bolt — whether undersized, wrong thread pitch, or insufficient tensile rating — can back out under vibration, allow components to shift, or cause damage to fuel, electrical, or structural assemblies. The Multiquip 0010120050 Hex Head Bolt ensures the correct clamp load and thread engagement are maintained, keeping generator components properly secured through demanding duty cycles. Using a worn or incorrect fastener risks equipment damage, fluid leaks, or safety hazards on the jobsite.
