The Wacker Neuson 5100012785 is a genuine OEM Cheese-Head Screw designed for the RD24, RD27, and RD28 series tandem rollers. Sourced directly from Wacker Neuson, this fastener meets the exact specifications called out in the original equipment design. Fitment covers a wide range of RD-series configurations, including standard, DPF, and US-market variants across the RD24-100, RD27-120, and RD28-120 model lines.
Key Features
- OEM-Grade Fastener Specification — Manufactured to the exact thread form, head profile, and material grade specified for Wacker Neuson tandem roller assemblies, ensuring correct clamp load and seating depth.
- Drop-In Installation — The cheese-head profile seats flush into its designated bore without modification, aligning with the original mounting geometry on RD-series roller components.
- Broad RD-Series Coverage — Compatible with RD24-100, RD27-120, and RD28-120 tandem rollers, including standard, DPF-equipped, and US-market configurations.
- Structural Integrity Under Vibration — Tandem rollers operate under sustained vibration loads; a correctly specified fastener maintains clamping force and resists loosening during asphalt and soil compaction cycles.
- Genuine Wacker Neuson Part — Carries the OEM part number 5100012785, so you can verify the correct part against your machine's parts diagram before ordering.
A cheese-head screw is a cylindrical-headed fastener commonly used in mechanical assemblies where a low-profile, high-strength connection is required within tight or recessed clearances. On tandem rollers like the RD24, RD27, and RD28, fasteners of this type secure critical components that must hold their position through constant vibration and variable compaction loads. Using an incorrectly specified screw — wrong thread pitch, head height, or material grade — can lead to fastener failure, component movement, or damage to surrounding parts over time.
