The Wacker Neuson 5100011478 is a genuine OEM Hexagon Screw designed for the RD40-130 and RD45-140 tandem roller series and the RC110 single-drum soil compactor. As a direct Wacker Neuson OEM part, 5100011478 is produced to the exact material grade and thread specification required for these machines, ensuring a correct, secure fit every time. This Hexagon Screw is compatible across multiple configuration variants within the RD40-130 and RD45-140 families, including open-drum, combination, and updated.3-series units, as well as both the RC110 and RC110P compactors.
Key Features
- Correct Thread Grade and Material Spec — Manufactured to the precise tensile strength and thread pitch required for structural fastening on Wacker Neuson compaction equipment, preventing stripping or fastener failure under vibration.
- Genuine OEM Part — Sourced directly from Wacker Neuson, this Hexagon Screw carries the same part number used in original machine assembly, so you are installing an identical replacement.
- Broad RD and RC Series Compatibility — Fits RD40-130 and RD45-140 tandem rollers across open, combination, and .3-series variants, plus the RC110 and RC110P single-drum soil compactors.
- Vibration-Resistant Fastening — Compaction equipment operates under constant high-frequency vibration; a correctly rated Hexagon Screw maintains clamping force and prevents joint loosening during operation.
- Drop-In Replacement — Matches the original fastener dimensions exactly, so installation requires no reworking of mounting holes or hardware.
A hexagon screw is a standard hex-head fastener used throughout compaction equipment to secure structural panels, drive components, and assemblies that must withstand sustained mechanical stress and vibration. On tandem rollers and single-drum compactors, fasteners like this one are critical to maintaining the integrity of drum housings, frames, and drivetrain covers. When a fastener is stripped, incorrectly rated, or missing, it can allow components to shift or separate during operation, leading to accelerated wear or mechanical failure. Replacing a worn or damaged fastener with the correct OEM-spec Hexagon Screw restores the original clamping load and keeps the assembly secure.
