The Wacker Neuson 5100012549 is a genuine OEM Hexagon Nut designed for the RD18, RD24, RD27, and RD28 series walk-behind and ride-on tandem rollers. Sourced directly from Wacker Neuson, this fastener meets the exact material and dimensional specifications required for these machines. It fits an extensive range of variants across the RD tandem roller lineup, including DPF, C, O, SE, and US-spec configurations. When your machine calls for part number 5100012549, this is the correct OEM replacement to keep your roller running as designed.
Key Features
- Genuine OEM Fastener Grade — Manufactured to Wacker Neuson's specified thread pitch, hardness, and torque rating for secure, lasting clamping force in roller applications.
- Drop-In Replacement — Matches the original hex profile and thread specification exactly, so installation requires only standard hand tools with no reworking of mating hardware.
- Broad RD Series Coverage — Confirmed fitment across RD18-80, RD18-100, RD24-100, RD27-120, and RD28-120 tandem rollers, including DPF-compliant, combination drum, and canopy variants.
- Structural Integrity Where It Counts — A correctly torqued fastener maintains critical joint clamp loads on a tandem roller; a worn, stripped, or incorrect nut risks joint loosening under continuous vibration loads on compaction passes.
A hexagon nut is a threaded fastener used to clamp and secure bolted connections throughout a machine. On a tandem roller like the RD18, RD24, RD27, and RD28 series, fasteners are exposed to sustained vibration during every compaction pass, which makes correct grade and thread specification essential. A worn or incorrect nut can back off under load, leading to loose assemblies, component misalignment, or accelerated wear of surrounding hardware. Replacing a failed or damaged nut with the correct OEM-spec 5100012549 restores the designed clamping force and keeps critical joints tight through demanding compaction work.
