Multiquip M9220100004 Set Screw

The Multiquip M9220100004 Set Screw is a genuine OEM component designed for DCA and NGA series ultra-silent and super-silent diesel generators. As a direct OEM replacement, this set screw is manufactured to the same specifications as the original hardware, ensuring correct installation and secure mechanical retention across the full range of compatible generator models. Verified fitment spans a wide range of DCA series configurations, including DCA25, DCA45, DCA70, DCA125, DCA150, DCA180, DCA220, and DCA300 variants, as well as select NGA series and DIS185SSI4F air compressor units.

Key Features

• Genuine OEM Hardware Grade — Manufactured to Multiquip's original specification, ensuring the correct thread pitch, hardness, and drive type for secure mechanical retention in generator assemblies.
• Direct Drop-In Installation — Matches the original fastener profile exactly, seating and torquing to spec without rework or modification to the surrounding components.
• Broad DCA and NGA Series Compatibility — Fits an extensive range of Multiquip ultra-silent and super-silent generator models from the DCA25 through DCA300 series, plus select NGA150 natural gas alternator units.
• Maintains Mechanical Integrity — A correctly installed set screw prevents shaft, collar, or component movement that can lead to misalignment, vibration-induced wear, or premature failure of surrounding parts.
• Verified Part Number — Order with confidence using Multiquip part number M9220100004 to ensure you receive the correct fastener for your specific generator model.

A set screw is a headless fastener threaded fully along its length and driven flush into a tapped hole to lock a component — such as a shaft collar, gear, pulley, or bracket — firmly against a mating surface or shaft. In generator assemblies, set screws are used throughout the drivetrain, enclosure, and ancillary component mounts to prevent rotational or axial movement under load and vibration. When a set screw loosens or fails, the component it secures can shift out of alignment, generating excessive wear, unwanted noise, or outright mechanical failure of the assembly it holds in place.
