The Wacker Neuson 5100012232 is a genuine OEM Cap Nut designed for the RD18 series tandem rollers and RC110 single-drum soil compactors. This fastener is direct-sourced from Wacker Neuson, ensuring it matches the original hardware specification used during machine assembly. Compatible models include the RD18-80, RD18-100, RD18-100c, and the full RC110 and RC110P lineup, including US CAB, US ROPS, and padfoot configurations.
Key Features
- Genuine OEM Fastener Grade — Manufactured to the exact thread pitch, torque rating, and material grade specified for RD18 and RC110 series applications, ensuring secure clamping without risk of stripping or backing out under vibration.
- Drop-In Hardware Replacement — Matches the original cap nut position and thread engagement on the machine, allowing straightforward installation without reworking the mounting point.
- Broad RD18 and RC110 Coverage — Confirmed fitment across RD18-80, RD18-100, RD18-100c, RC110, and RC110P variants including SE, US CAB, and US ROPS configurations.
- Vibration-Resistant Retention — Cap nut design provides enclosed thread protection, shielding the fastener from debris, moisture, and the constant vibration loads generated during compaction cycles.
- Protects Threaded Hardware — The cap profile covers and seals the exposed thread end, preventing corrosion and thread damage that would otherwise complicate future disassembly and servicing.
A cap nut is a closed-end fastener that threads onto a bolt or stud and covers the exposed thread tip with a domed cap. On compaction and roller equipment like the RD18 and RC110 series, cap nuts serve both a mechanical and protective function — they secure components under sustained vibration while shielding the bolt threads from dirt, moisture, and corrosion. When a cap nut strips, cracks, or corrodes in place, it can compromise joint integrity and make future maintenance significantly more difficult, often damaging the underlying stud in the process.
