The Wacker Neuson 5100012823 is a genuine OEM Cheese-Head Screw designed for the RD-series tandem rollers and RC110 single-drum soil compactors. Sourced directly from Wacker Neuson, this fastener matches the exact material grade, thread specification, and head geometry of the original hardware installed at the factory. Confirmed fitment spans the RD24-100, RD27-120, RD28-120, RD40-130, and RD45-140 tandem roller families — including open-drum, combination, and DPF-equipped variants — as well as the RC110 ROPS and RC110 CAB configurations.
Key Features
- OEM-Grade Fastener Material — Manufactured to the exact material and hardness specification of the original, ensuring consistent clamping force and thread integrity throughout the service life of the machine.
- Correct Head Profile for Tool Access — The cheese-head (raised cylindrical) profile provides a deep, positive driver engagement, reducing the risk of cam-out or rounding during installation and removal in tight machine cavities.
- Broad Tandem Roller Compatibility — Fits RD24-100, RD27-120, RD28-120, RD40-130, and RD45-140 series tandem rollers across open-drum, combination, and DPF configurations, plus RC110 ROPS and RC110 CAB single-drum compactors.
- Direct Drop-In Replacement — Part number 5100012823 cross-references directly to the original Wacker Neuson service part, so it installs without modification using standard tooling already on your service truck.
- Protects Structural Integrity at Fastened Joints — A worn, stripped, or incorrect screw at a critical joint can lead to vibration-induced loosening and component movement under the high-cycle compaction loads these machines produce; the correct OEM fastener maintains proper clamp load at every torque-to-spec.
A cheese-head screw is a precision fastener characterized by its cylindrical, flat-topped head with a diameter larger than a standard cap screw, distributing clamping load evenly across the mating surface without the need for a washer in many applications. On heavy compaction equipment like tandem rollers and single-drum compactors, fasteners are subject to continuous vibration and dynamic loading, which can accelerate wear and loosening if the incorrect grade or geometry is used. Replacing a damaged or missing fastener with the correct OEM part — verified by part number 5100012823 — ensures the joint maintains its design clamping force and keeps critical assemblies secure during operation.
