Wacker Neuson 5100012546 Hexagon Nut

The Wacker Neuson 5100012546 is a genuine OEM Hexagon Nut designed for the RC and RD series of compaction equipment, covering single-drum soil compactors and tandem rollers across a wide range of configurations. Sourced directly through Wacker Neuson's authorized parts network, this nut meets the exact dimensional and material standards of the original hardware used on these machines. It is confirmed to fit the RC50, RC70, and RC110 single-drum soil compactor families, as well as the RD18, RD24, RD27, RD28, RD40, and RD45 tandem roller series, including DPF, cab, ROPS, and open-station variants. Keeping the correct fastener in service ensures structural integrity and proper torque retention wherever this nut is specified in the assembly.

Key Features

• Genuine OEM Hardware Grade — Manufactured to the exact thread pitch, hardness rating, and dimensional tolerance specified by Wacker Neuson, ensuring correct clamping force and thread engagement in the original fastener position.
• Drop-In Replacement — Matches the OEM hex profile and thread specification exactly, so it installs directly using standard tooling without reworking the mating hardware.
• Broad Fitment Across RC and RD Families — Compatible with RC50, RC70, and RC110 single-drum soil compactors and RD18 through RD45 tandem rollers, spanning gasoline, diesel, DPF, cab, ROPS, and open-station configurations.
• Torque Retention Under Vibration — Compaction equipment generates sustained mechanical vibration; a properly rated OEM nut resists loosening and maintains the clamp load that keeps assemblies secure through continuous working cycles.
• Fastener Integrity for Safety-Critical Connections — Using the correct specified fastener is essential on compaction machines where under-torqued or mismatched hardware can lead to joint failure in structural or drivetrain assemblies.

A hexagon nut is a threaded fastener used to secure bolted joints throughout a machine's frame, drivetrain, and ancillary assemblies. On heavy compaction equipment like single-drum soil compactors and tandem rollers, fasteners are subject to constant vibration and dynamic loading, making the correct grade and thread specification critical to long-term joint integrity. When a nut is worn, cross-threaded, or of an incorrect specification, it can fail to hold the required clamp load — leading to loosening, component movement, or joint failure during operation.
