Multiquip 0021006080 Machine Screw

The Multiquip 0021006080 Machine Screw is a genuine OEM fastener designed for DCA and NGA series ultra-silent and super-silent diesel generators. As a direct OEM replacement, this screw is manufactured to the exact specifications required to maintain the structural and mechanical integrity of your generator enclosure and internal assemblies. Confirmed fitment includes a wide range of DCA125, DCA150, and NGA150 series models, including DCA125SSIU, DCA125SSJU, DCA150SSJU, DCA150SSVU, DCA150USJ, and NGA150SSPUPL variants. Sourcing the correct OEM hardware ensures the fastener seats, threads, and torques exactly as the machine was built to spec.

Key Features

• Genuine OEM Hardware Spec — Manufactured to the exact thread pitch, head profile, and material grade specified for DCA and NGA series generator assemblies.
• Direct-Fit Replacement — Threads directly into existing tapped locations with no modification to mating components or mounting surfaces required.
• Broad DCA/NGA Series Compatibility — Fits DCA125, DCA150, and NGA150 super-silent and ultra-silent generator models across multiple production variants and frequency configurations.
• Structural Integrity Assurance — Using the correct fastener prevents panel flex, misalignment, and vibration-induced loosening in high-cycle generator operation.
• Correct Torque Retention — Proper thread engagement and head geometry ensure consistent clamping force, critical for enclosure panels and internal bracket mounting on large diesel generators.

A machine screw is a precision fastener used to secure panels, brackets, covers, and internal components throughout a generator's enclosure and drivetrain assembly. In a diesel generator like the DCA or NGA series, dozens of machine screws hold together sound-dampening enclosure panels, control housings, and structural brackets — meaning the correct thread form and head type are essential for consistent clamping force and vibration resistance. Using an incorrect or undersized fastener in these applications can lead to panel loosening, misalignment, or premature fatigue failure, particularly given the continuous vibration loads produced during generator operation.
