Wacker Neuson 5100063995 Counter Nut

The Wacker Neuson Counter Nut is a genuine OEM component designed for RC110 and RC110p series compactors, covering both ROPS and CAB configurations. Sourced directly from Wacker Neuson, this part meets the exact specifications of the original hardware installed at the factory. It is a direct replacement for the RC110 US ROPS, RC110p US ROPS, RC110 US CAB, and RC110p US CAB machines, so you can install with confidence knowing the fit and function are correct. Keep a spare on hand to avoid unnecessary delays when routine maintenance or repairs come due.

Key Features

• OEM Thread Integrity — Manufactured to the exact thread pitch and hardness grade of the original, ensuring secure locking engagement without stripping or backing off under vibration.
• Drop-In Replacement — Matches the original mounting position and torque spec on RC110 and RC110p compactors, so installation requires no reworking of adjacent components.
• Broad Model Coverage — Fits RC110 US ROPS, RC110p US ROPS, RC110 US CAB, and RC110p US CAB variants under a single part number.
• Vibration Resistance — A properly seated counter nut maintains fastener tension in high-vibration compactor applications, preventing loosening that can lead to component misalignment or damage.
• Genuine Wacker Neuson Part — Supplied as authentic OEM hardware, verified by part number 5100063995, so you are getting the same component Wacker Neuson uses in production.

A counter nut — also known as a jam nut — is a secondary fastener threaded against a primary nut or bolt to lock it firmly in position. On compactors like the RC110 series, where constant vibration is a normal operating condition, counter nuts play a critical role in keeping assemblies secure throughout the machine's working life. When a counter nut wears, strips, or goes missing, the primary fastener can gradually loosen, potentially causing mechanical play, component wear, or failure of the assembly it secures.
