The Wacker Neuson 5100012199 is a genuine OEM Hollow-Core Screw designed for the RD series tandem roller lineup. As a direct OEM replacement, this part is produced to the same specifications as the original component installed at the factory, ensuring consistent performance across the full range of compatible machines. Fitment covers an extensive span of RD tandem roller models, including the RD18, RD24, RD27, RD28, RD40, and RD45 series in standard, combination, and open-drum configurations. Always confirm your machine's model and serial number against part number 5100012199 before ordering.
Key Features
- Genuine OEM Construction — Manufactured to the exact material and thread specification of the original screw, ensuring consistent torque retention and secure clamping in roller assemblies.
- Hollow-Core Design for Integrated Flow — The through-bore channel allows fluid or fastener passage within the assembly, making correct part selection critical to maintaining system integrity.
- Broad RD Series Compatibility — Fits RD18, RD24, RD27, RD28, RD40, and RD45 tandem roller models across US, standard, combination drum, and open-drum variants.
- Drop-In OEM Replacement — Matches original mounting points and thread engagement dimensions, allowing straightforward installation without modification to surrounding hardware.
- Supports Compaction System Integrity — A correctly seated hollow-core screw maintains the structural and hydraulic integrity of the roller assembly; a failed or improperly replaced fastener can compromise drum operation and machine control.
A hollow-core screw is a specialized fastener with an internal through-bore that serves a dual purpose: it secures components within the assembly while simultaneously allowing fluid, air, or a secondary element to pass through its center. In tandem roller applications, this type of screw is commonly found in hydraulic or vibration system assemblies where both clamping force and internal passage routing are required at the same location. If this screw is damaged, incorrectly torqued, or replaced with a solid fastener, the internal flow path is interrupted, which can lead to system pressure loss, improper vibration function, or accelerated wear on adjacent components.
