The Wacker Neuson is a genuine OEM Flange Nut 20mm designed for a range of Wacker Neuson ride-on trowels, tandem rollers, floor saws, and portable generators. As a factory-sourced component, part is manufactured to the exact material grade and dimensional tolerances specified for these machines, ensuring a direct, secure fit without the guesswork. Confirmed fitment includes the CRT36-24A series ride-on trowels, RD12A-90 tandem rollers, BFS 2020AS floor saw, RD11A and RD11AEC hydrostatic double drum vibratory rollers, and the GS12Ai portable generator. Sourcing the correct fastener from Wacker Neuson keeps critical assemblies properly torqued and structurally sound across demanding jobsite conditions.
Key Features
- Precise OEM Thread and Flange Dimensions — Manufactured to the exact 20mm specification, ensuring correct clamping load and thread engagement in every application.
- Integrated Flange Design — The built-in flange distributes bearing load evenly across the mating surface, reducing the risk of fastener loosening under vibration.
- Broad Cross-Equipment Fitment — Fits CRT36-24A ride-on trowels, RD12A-90 tandem rollers, RD11A and RD11AEC rollers, BFS 2020AS floor saw, and GS12Ai generator — one part number covering multiple machine families.
- Vibration-Resistant Retention — Critical on compaction and concrete finishing equipment where sustained vibration can back out under-spec fasteners, leading to assembly failure.
- Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, this fastener meets the same material and hardness standards as the nut originally installed at the factory.
A flange nut is a standard hex nut with a wide, integrated washer-like flange at its base. This flange spreads the clamping force over a larger surface area than a plain nut, making it especially effective in assemblies subject to vibration — a common condition in concrete trowels, roller compactors, floor saws, and generators. When a flange nut wears, strips, or is replaced with an incorrect size, it can result in undertorqued connections, component movement, and accelerated wear on surrounding hardware. Using the correct OEM-specified replacement like the Wacker Neuson 5000151923 ensures the joint retains the holding force the original design required.
