Wacker Neuson 5100012545 Hexagon Nut

The Wacker Neuson 5100012545 is a genuine OEM Hexagon Nut designed for the RC-series single-drum soil compactors and RD-series tandem rollers. As a direct OEM replacement, this nut is manufactured to the exact dimensions and material grade specified for these machines, ensuring a secure, correctly torqued connection every time. Fitment spans the RC50, RC70, and RC110 single-drum soil compactor families as well as the RD18, RD24, RD27, RD28, RD40, and RD45 tandem roller series, covering a wide range of walk-behind and ride-on compaction equipment. Sourcing part number 5100012545 directly ensures you are installing the correct hardware rather than a dimensionally similar substitute.

Key Features

• Genuine OEM Material Grade — Manufactured to Wacker Neuson's specified tensile strength and hardness rating for this fastener position, so clamping force is maintained under sustained vibration loads.
• Drop-In Hardware Replacement — Matches the original thread pitch, across-flats dimension, and height exactly, so it seats and torques to spec without chasing threads or shimming.
• Broad Compaction Equipment Compatibility — Verified fit across RC50, RC70, and RC110 single-drum soil compactors and RD18 through RD45 tandem roller variants, including DPF, CAB, ROPS, and open-rollbar configurations.
• Vibration-Environment Integrity — A properly spec'd hexagon nut in a compactor or roller application resists loosening caused by continuous drum vibration; an incorrect or worn nut can back off and compromise structural or mechanical connections.
• OEM Part Number Traceability — Carrying part number 5100012545, this nut is fully traceable through the Wacker Neuson parts system, making reordering and service documentation straightforward.

A hexagon nut is a fundamental threaded fastener used throughout compaction equipment to clamp components together and maintain structural integrity at bolted joints. On vibratory machines such as tandem rollers and single-drum soil compactors, fasteners are subjected to constant dynamic loading and must meet precise dimensional and hardness tolerances to hold their clamping force over time. When a nut backs off, stretches beyond its yield point, or is replaced with an incorrect grade, the bolted joint loses preload, which can lead to component movement, accelerated wear at mating surfaces, or mechanical failure of the assembly it secures.
