Wacker Neuson 5000010872 Hex Nut M4 8

The Wacker Neuson is a genuine OEM Hex Nut M4 8 designed for the broad range of Wacker Neuson G-series portable and mobile generators, including the G25, G50, G70, G85, G100, G120, G130, G150, G180, G230, G240, and G320 families, as well as GPS and GS-series portable generator models. As a genuine OEM component, is produced to Wacker Neuson's exact material and dimensional specifications, ensuring it seats and torques correctly in the application it was built for. This hex nut serves across an extensive range of generator configurations — standard, cold weather, custom, skid-mounted, and extended run variants — making it a high-demand service item for fleet operators and service technicians. Confirm your machine's model number against the fitment list before ordering to ensure you receive the correct fastener specification.

Key Features

• Genuine OEM Specification: — Manufactured to Wacker Neuson's precise M4 thread pitch and grade 8 hardness rating, delivering the correct clamp load and corrosion resistance for generator enclosure and component fastening applications.
• Direct-Thread Replacement: — Replaces the original hex nut on a like-for-like basis; threads directly onto existing M4 fastener locations with no reworking of mating hardware required.
• Broad Generator Family Coverage: — Fits G25, G50, G70, G85, G100, G120, G130, G150, G180, G230, G240, and G320 mobile and skid-mounted generators, as well as GPS9700, GS-series, and select IREN/IRFU internal vibrator models across multiple configuration variants.
• Structural Integrity at Every Service Interval: — A correctly torqued, undamaged hex nut keeps panels, brackets, and ancillary components secure under generator vibration and load cycling; a stripped or missing fastener can allow components to shift or loosen in service.
• Authorized Part Sourced Directly: — Sold as a genuine Wacker Neuson OEM part, carrying the same part number — 5000010872 — used by authorized Wacker Neuson dealers and service centers worldwide.

A hex nut is a six-sided internally threaded fastener used to clamp two or more components together when paired with a bolt or threaded stud. In generator applications, hex nuts are used throughout the enclosure, frame, and component mounting points to maintain structural integrity during operation, transport, and service. Over time, fasteners can become corroded, stripped, or lost during routine maintenance, and replacing them with a correctly graded and dimensioned OEM part ensures that torque specifications can be properly met. Using an undersized or incorrect-grade fastener risks inadequate clamping force, which can lead to loosened panels or components during operation.
