The Wacker Neuson 5100012090 is a genuine OEM Cheese-Head Screw designed for the full RD-series tandem roller lineup. As a factory-sourced fastener, it is manufactured to the exact dimensions and material specification required for correct installation and secure clamping force within the machine. Fitment spans the RD18, RD24, RD27, RD28, RD40, and RD45 tandem roller families across a wide range of configurations, including standard, combination, open-drum, and DPF variants. Using the correct OEM fastener — part number 5100012090 — ensures threads engage properly and torque loads are distributed as engineered.
Key Features
- OEM Thread and Head Geometry — Manufactured to the exact head diameter, drive recess depth, and thread pitch specified by Wacker Neuson, ensuring full engagement and correct torque values on installation.
- Direct-Fit Installation — Drops into the same seat and thread bore as the original, with no chasing, rethreading, or modification to mating components required.
- Broad RD-Series Compatibility — Covers RD18, RD24, RD27, RD28, RD40, and RD45 tandem rollers across standard, open-drum, combination-drum, and DPF-equipped variants.
- Structural Integrity Under Vibration — Tandem rollers generate constant vibration during operation; a correctly spec'd fastener maintains clamping load and resists loosening where an undersized or mismatched screw would back out.
- Genuine Wacker Neuson Part — Sourced directly from Wacker Neuson, carrying the same part number — 5100012090 — used by authorized dealers and service technicians worldwide.
A cheese-head screw is a cylindrical-head fastener with a flat top and straight sides, commonly used in mechanical assemblies where a low-profile, high-contact-area head is needed to distribute clamping load without the risk of the head pulling through or spinning in a counterbore. In a tandem roller, fasteners like this one secure panels, guards, housings, and internal brackets that must remain firmly in place through continuous vibration and heavy-duty compaction cycles. When a screw of this type strips, backs out, or is replaced with an incorrect substitute, the clamped joint can loosen progressively, leading to component movement, accelerated wear on mating surfaces, or loss of a guard or cover during operation.
