As a direct Wacker Neuson OEM part, the is manufactured to the exact specifications used in original assembly, ensuring correct thread engagement, collar retention, and dimensional fit across all compatible RD7 configurations. This nut is used across multiple RD7 build variants, making it a commonly needed service item for operators and technicians maintaining these machines in the field or shop.
Key Features
- OEM Thread and Collar Specification — Manufactured to the exact M10 thread pitch and collar geometry specified for RD7 series assembly, ensuring full engagement and correct clamping force.
- Integrated Collar Retention — The captive collar design resists loosening under vibration, which is critical on compaction equipment subject to continuous dynamic loading during operation.
- Broad RD7 Series Compatibility — Fits RD7H-ES, RD7H-S, and base RD7 double-drum vibratory roller configurations, including EU-spec variants.
- Drop-In Replacement — Matches original fastener dimensions, so it installs in the existing position without rework or modification to surrounding hardware.
- Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, carrying the same part number used in the original build — verified by part number 5000164272.
A hex nut with collar is a fastener that combines a standard hex nut with an integrated flanged collar, which distributes clamping load over a wider bearing surface and helps resist self-loosening under vibration. On a tandem roller like the RD7 series, where the entire machine operates under sustained vibration during compaction passes, fastener integrity is essential — a loose or failed nut can allow structural components to shift, leading to misalignment, accelerated wear on adjacent parts, or unsafe operating conditions. Replacing worn or damaged hardware with the correct OEM fastener maintains the integrity of the assembly and the safety of the machine.
