The Wacker Neuson 5100012918 is a genuine OEM Hollow Core Screw designed for the RD24, RD27, and RD28 series walk-behind and ride-on articulated tandem rollers. Sourced directly from Wacker Neuson, this part carries the same specifications as the original hardware installed at the factory. Fitment covers a broad range of RD24-100, RD27-120, and RD28-120 variants — including open-drum, combination, and DPF-equipped configurations sold in the US and international markets. When it's time to replace a worn or damaged hollow core screw, part number 5100012918 is the correct, verified replacement for your machine.
Key Features
- Genuine OEM Threaded Integrity — Manufactured to the exact thread pitch, shank diameter, and internal bore geometry specified for the RD-series tandem roller, ensuring consistent torque retention and hydraulic or fluid passage function.
- Drop-In Replacement — Matches the original mounting configuration on RD24-100, RD27-120, and RD28-120 platforms; installs using standard tooling with no reworking of surrounding hardware.
- Broad RD-Series Coverage — A single part number spans open-drum, closed-drum, combination, and DPF variants of the RD24, RD27, and RD28, simplifying parts sourcing across a mixed fleet.
- Maintains Fluid Passage Performance — The hollow bore design allows controlled fluid or hydraulic routing through the fastener itself; a worn or damaged screw can disrupt flow paths and cause downstream system issues.
- Verified Wacker Neuson OEM Part — Part number 5100012918 is confirmed against Wacker Neuson's official parts documentation, so you order with confidence that the part matches your machine's bill of materials.
A hollow core screw is a fastener with a precision-bored internal channel that serves a dual purpose: it secures components mechanically while also allowing fluid, hydraulic oil, or lubricant to pass through its center to feed an adjacent system. In tandem rollers like the RD24, RD27, and RD28, these screws are typically used in hydraulic or lubrication circuits where both clamping force and controlled fluid delivery are needed in a single compact component. If the screw becomes damaged, corroded, or develops a blocked bore, the affected circuit can lose pressure or lubrication, potentially causing accelerated wear or system failure in the components it serves.
