Wacker Neuson 5000013178 Hex Nut M4 Ms

The Wacker Neuson Hex Nut M4 Ms is a genuine OEM fastener designed for Wacker Neuson internal and external concrete vibrators across the IRFU, IREN, IRSEN, IRFUN, ARFU, and AR series. As a direct OEM replacement, this part is sourced from Wacker Neuson's production supply chain, ensuring it meets the same material and dimensional standards as the hardware installed at the factory. This nut fits an extensive range of models, including the IRFU30, IRFU38, IRFU45, IRFU58, IRFU65, IREN, IRSEN, and AR external vibrator families, as well as associated frequency converters in the SFU and FU series. Confirm your model number before ordering to ensure correct application.

Key Features

• Genuine OEM Brass Construction — The M4 Ms designation indicates a brass (Messing) material specification, providing the corrosion resistance and torque characteristics required in vibrator housings and electrical enclosures.
• Direct Bolt-In Replacement — Matches the M4 thread pitch and seating geometry of the original fastener, allowing straightforward installation without reworking the mating hardware.
• Broad Vibrator Family Coverage — Compatible across IRFU, IREN, IRSEN, IRFUN, ARFU, and AR internal and external concrete vibrator models, plus SFU and FU frequency converter units.
• Maintains Structural Integrity of Fastened Joints — A properly spec'd brass hex nut holds clamping force without galvanic corrosion against the mating stud or bolt; a mismatched or worn fastener can lead to loose assemblies and premature component failure.
• Electrical Safety Relevance — Used within vibrator housings and converter enclosures where secure fastening of electrical components is critical; replacing with the correct material grade helps preserve safe, intended operation of the equipment.

A hex nut is a threaded fastener that mates with a bolt or stud to clamp components securely together within an assembly. In concrete vibrators and frequency converters, fasteners like the 5000013178 are used to secure internal components, cover plates, and electrical enclosure hardware where vibration loads are constant during operation. The brass material grade resists corrosion in wet concrete environments and avoids galvanic compatibility issues with the mating hardware. When a fastener loosens, strips, or corrodes, it can compromise the integrity of the assembly, lead to component movement under vibration, and in electrical enclosures, create unsafe conditions — making timely replacement with the correct OEM specification part essential.
