The Wacker Neuson is a genuine OEM Flange Nut 5mm designed for a broad range of Wacker Neuson portable generators, vibratory rammers, backpack vibrators, pole vibrators, and power units. This small but critical fastener is sourced directly from Wacker Neuson, ensuring the correct thread pitch, flange diameter, and material specification for every application it covers. Compatible models span the GP3800A, GP5600A, GP6600A, GPS5600A, and GPS6600A generator families, as well as the BS50-4As, BS60-4As, BS65-4As, BS70-4As, and BS72-4As vibratory rammer series, plus BV and PV backpack and pole vibrators. Always cross-reference your machine's model number and serial number before ordering to confirm an exact match.
Key Features
- Genuine OEM Fastener Integrity — Manufactured to Wacker Neuson's own thread and flange tolerances, so clamping load and seating behavior match the original assembly exactly.
- Broad Cross-Family Coverage — A single part number spans GP/GPS portable generators, BS/MS vibratory rammers, BV/PV vibrators, and P35A power units, making it a practical stock item for mixed Wacker Neuson fleets.
- Drop-In Installation — The integrated flange distributes clamping force evenly across the mating surface, seating the same way as the factory fastener without additional washers or hardware.
- Corrosion and Vibration Resistance — Engineered to retain its grip under the sustained mechanical vibration generated by rammers and vibratory equipment, reducing the risk of loosening in service.
- Fuel and Electrical System Safety — Used in assemblies that may secure fuel system and electrical covers; using the correct OEM specification nut helps maintain proper torque retention and prevent accidental loosening in safety-critical zones.
A flange nut is a hex nut with an integrated wide-diameter collar — or flange — on one face that acts as a built-in washer. This flange spreads the clamping load over a larger surface area, reducing the risk of the fastener pulling through or distorting the mating material. In high-vibration equipment such as vibratory rammers and concrete vibrators, standard nuts can work loose over time; the flange design helps the fastener maintain its torque under continuous oscillation. When a flange nut stretches, strips, or corrodes, it can allow covers, brackets, or component housings to shift or come free — replacing it promptly with the correct OEM part keeps assembled joints secure and the machine operating as intended.
