The Wacker Neuson Bolt is a genuine OEM bolt designed for MG3 and MG5 series portable generators. Sourced directly from Wacker Neuson, this part carries the same specifications as the original hardware installed at the factory, ensuring a correct, trouble-free fit. It is compatible across a broad range of MG3 and MG5 generator configurations, including standard, dual-voltage, and sound-dampened variants.
Key Features
- Genuine OEM Hardware Grade — Manufactured to the exact thread pitch, shank diameter, and tensile strength specified for MG3 and MG5 generator assemblies, so clamping force and torque values remain consistent with original design intent.
- Direct Drop-In Replacement — Matches the original bolt profile and threading, allowing straightforward installation without reworking mounting points or hardware clearances.
- Broad MG3 and MG5 Compatibility — Verified fitment across numerous MG3, MG3sd, MG5, and MG5d portable generator models, covering standard and specialty configurations within both series.
- Structural Integrity Where It Counts — A correct, properly torqued bolt keeps generator components securely seated under load and vibration; a worn, stripped, or incorrect bolt can allow panels or assemblies to shift and cause progressive damage.
- Genuine Wacker Neuson Part — Carrying part number 5000404058, this bolt is an authorized OEM component backed by Wacker Neuson's parts program, giving you confidence the hardware matches the original specification exactly.
A bolt may be one of the smallest components in a generator assembly, but it plays a direct role in holding structural panels, mounting brackets, and mechanical assemblies firmly in place during operation. Generators produce continuous vibration under load, and an improperly sized or worn bolt can work loose over time, allowing components to shift, misalign, or cause secondary damage to surrounding parts. Using the correct OEM-specified bolt ensures the joint maintains its intended clamping load and that the assembly performs as designed throughout its service life.
