The Wacker Neuson is a genuine OEM Flange Nut 5Mm designed for a wide range of Wacker Neuson equipment, including RD12A-90 tandem rollers, CRT36-24A and CRT36-26A ride-on concrete trowels, the BFS 2020AS floor saw, GS12Ai and GPS9700A portable generators, and the RD11A and RD11AEC hydrostatic double drum vibratory rollers. Sourced directly from Wacker Neuson, part meets the exact dimensional and material standards of the original hardware. This nut is a direct drop-in replacement requiring no modification to the existing fastener location. Having the correct hardware on hand ensures critical assemblies stay properly torqued and secure across daily operation.
Key Features
- Genuine OEM Spec Hardware: — Manufactured to Wacker Neuson's exact thread pitch, flange diameter, and material hardness spec for the 5Mm flange nut application — no dimensional guesswork.
- Direct Bolt-On Replacement: — Matches the original fastener profile for a flush-seating flange contact, ensuring proper clamp load when torqued to spec.
- Broad Equipment Compatibility: — Verified fitment across RD12A-90 and RD11A series tandem rollers, CRT36-24A and CRT36-26A ride-on trowels, BFS 2020AS floor saw, and GS12Ai and GPS9700A generator models.
- Maintains Fastener Integrity: — A correctly spec'd flange nut distributes clamping force evenly across the bearing surface, preventing fastener loosening under vibration and load cycles common to compaction and concrete finishing equipment.
- Critical Safety Application: — Fastener hardware on rotating and vibrating assemblies is subject to continuous stress; using the correct OEM-spec nut prevents joint failure that can compromise operator safety and machine reliability.
A flange nut is a standard hex nut with an integrated wide-diameter washer flange built into one face. The flange spreads the clamping load over a larger surface area than a plain nut, which is especially important on assemblies exposed to vibration — such as those found on compaction rollers, concrete trowels, and floor saws — where an undersized or incorrect nut can work loose over time. When a flange nut wears, strips, or is replaced with an incorrect substitute, the joint can lose clamp force, leading to component movement, accelerated wear on mating parts, or outright fastener failure during operation.
