Multiquip 0016910025 Hex Head Bolt

The Multiquip 0016910025 Hex Head Bolt is a genuine OEM fastener designed for DCA Ultra-Silent and Super-Silent generators, NGA natural gas alternators, DIS air compressors, and MQP standby generator models. As a direct OEM replacement, this bolt meets the original engineering specifications Multiquip built into these machines, ensuring correct clamping force and thread engagement across all covered applications. Whether you are servicing a DCA45, DCA70, DCA125, DCA150, DCA180, DCA220, DCA300, DCA400, or DCA600 series unit, this is the bolt specified for that application. DHS Equipment stocks genuine Multiquip parts so you can get the right component and get your equipment back in service quickly.

Key Features

• Genuine OEM Fastener Grade — Manufactured to the exact tensile strength and thread specification Multiquip requires for these generator and compressor assemblies, so clamping loads are correct the first time.
• Direct Drop-In Replacement — Matches the original bolt profile, head dimensions, and threading so it seats into existing mounting points without modification.
• Broad Generator and Compressor Coverage — Fits an extensive range of DCA Ultra-Silent and Super-Silent series units, NGA natural gas alternators, DIS air compressors, and MQP standby generators across multiple tier and frequency configurations.
• Structural Integrity Under Load — A correctly torqued OEM bolt prevents loosening of critical assemblies during operation; a worn, incorrect, or under-spec bolt risks component movement, vibration damage, and unplanned failures on a running generator.
• Fuel and Fluid System Safe — Where used in fuel, coolant, or oil circuit assemblies, the correct bolt specification prevents leak paths caused by improper thread fit or insufficient clamp load.

A hex head bolt is a foundational fastener that secures structural panels, engine mounts, enclosure frames, and mechanical subassemblies together under defined torque. In generator sets and air compressors, fasteners are subjected to continuous vibration, thermal cycling, and load variation — conditions that expose any mismatch in grade, thread pitch, or head size. Using the correctly specified OEM bolt ensures the joint maintains its designed clamping force throughout service intervals. When a bolt is missing, stripped, or substituted with an off-spec part, it can allow components to shift or vibrate loose, leading to accelerated wear, fluid leaks, or structural damage to the surrounding assembly.
