The Multiquip 9111750120 Nut is a genuine OEM fastener designed for DCA-series ultra-silent diesel generators, including the DCA40SSAI, DCA40SSI, DCA45SSIU2, DCA45SSIU2-GEER, and DCA45SSIU2-FEMA. As an authentic Multiquip OEM part, it is manufactured to the exact dimensional and material specifications required for correct installation and secure retention within these generator assemblies. Sourcing the correct fastener matters — an improperly spec'd nut can compromise clamping force and lead to component loosening under sustained generator load. Verify your model code against the fitment list above before ordering to ensure a direct match.

A nut is a threaded fastener that works in conjunction with a bolt or stud to clamp components securely together within an assembly. In generator equipment such as the DCA-series ultra-silent units, fasteners like this one are used throughout the engine, alternator, frame, and enclosure systems to maintain structural integrity and vibration resistance during operation. Using a fastener that does not meet the correct thread specification or material grade can result in undertorquing, fastener failure, or damage to the mating threads — making an exact OEM replacement the dependable choice for any service or repair.
