The Wacker Neuson is a genuine OEM Nut M10 Flange Hex designed for the RD7 series walk-behind tandem rollers, including the RD7H-ES and RD7H-S models. As a direct OEM part, the is manufactured to the exact material grade, thread pitch, and flange geometry specified for these machines — ensuring it seats and torques correctly without guesswork. This part fits across the RD7 double drum vibratory roller family, covering both the EU-spec and standard configurations. Keep a spare on hand to avoid delays during scheduled maintenance or field repairs.
Key Features
- OEM-Grade Thread and Flange Specification — Manufactured to the exact M10 thread pitch and flange diameter called out for the RD7 series, so the nut clamps and locks as intended without risk of stripping or backing out under vibration.
- Built-In Flange for Secure Clamping — The integrated flange distributes load across a wider bearing surface, reducing the chance of fastener loosening on high-vibration compaction equipment like tandem rollers.
- Direct Fitment Across the RD7 Family — Verified fit for RD7H-ES, RD7H-S, and RD7 double drum vibratory roller variants, including EU-spec and standard configurations.
- Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, carrying the same part number — 5000111966 — used by authorized service centers, so you can be confident you're installing the correct component.
- Protects Surrounding Components — A worn or missing flange nut on a vibratory roller allows fastened assemblies to shift under load, which can accelerate wear on drums, frames, and drive components — replacing it promptly keeps those assemblies secure.
A hex flange nut combines a standard hex nut with a wide, integrated flange that acts like a built-in washer. On walk-behind tandem rollers such as the RD7 series, where constant vibration is a core part of machine operation, fasteners are exposed to continuous cyclic stress that can work standard nuts loose over time. The flange spreads clamping load over a larger contact area, resisting loosening and helping maintain the structural integrity of bolted joints throughout the machine. When a flange nut is missing, damaged, or replaced with an incorrect fastener, joint integrity is compromised — potentially allowing critical assemblies to shift or separate during operation.
