The Wacker Neuson 5100012931 is a genuine OEM Mushroom Head Screw designed for the RD-series tandem rollers, covering the RD18, RD24, RD27, RD28, RD40, and RD45 model families. As a factory-sourced component, it is manufactured to the exact specifications required by Wacker Neuson for correct fitment and consistent performance across this extensive roller lineup. This screw is a direct, drop-in replacement that installs just as the original did, with no modification to surrounding hardware or panels. Confirming your machine's model number against the fitment list before ordering ensures you receive the correct part for your specific configuration.
Key Features
- Genuine OEM Specification: — Manufactured to Wacker Neuson's original thread form, head profile, and material grade — ensuring the clamping force and seating depth match what the design requires for this fastener position.
- Broad RD-Series Coverage: — Compatible with a wide range of Wacker Neuson RD tandem rollers, including RD18, RD24, RD27, RD28, RD40, and RD45 variants in smooth-drum, combination, DPF, and electric configurations.
- Correct Head Geometry: — The mushroom head profile distributes clamping load over a wider bearing surface than a standard hex head, making correct head shape critical to proper panel or component retention in this application.
- Sourced Direct from Wacker Neuson: — Supplied as a genuine OEM part, this screw carries the same part number — 5100012931 — used by Wacker Neuson dealers and service centers, giving you confidence in what you are installing.
- Supports Structural Integrity: — Using the correct fastener in each position prevents loosening under vibration, which is a persistent stress condition in any operating tandem roller; substituting an incorrect head type or thread pitch risks progressive fastener failure.
A mushroom head screw is a fastener characterized by its wide, low-profile domed head, which spreads clamping force across a larger surface area than a conventional bolt head. In vibration-intensive equipment such as tandem rollers, fasteners in panel, housing, and guard positions are subject to continuous cyclical stress that can work a mismatched or worn screw loose over time. Using the correct OEM fastener — with the right head form, thread specification, and material — maintains the secure attachment that keeps covers, guards, and structural panels properly seated throughout the machine's service life.
