The Wacker Neuson 5100012595 is a genuine OEM Countersunk Screw designed for the RD40-130 and RD45-140 series tandem rollers. As a direct OEM replacement sourced through authorized Wacker Neuson supply channels, this screw is manufactured to the exact dimensions and material specifications required for proper fit and function. Fitment spans the full range of RD40-130 and RD45-140 variants, including standard, combination (c), offset (o), DPF, and.3-series configurations across both US and international market builds. When hardware integrity matters on a machine that handles daily asphalt and soil compaction loads, specifying the correct OEM fastener is the straightforward choice.
Key Features
- Genuine OEM Fastener Spec — Manufactured to the exact thread pitch, head geometry, and material grade called out in the Wacker Neuson parts system — no guesswork on substitutions.
- Flush-Mount Countersunk Head — The countersunk profile seats fully flush with the mating surface, ensuring panels, guards, or structural members sit correctly without interference or proud hardware.
- Broad RD-Series Coverage — Confirmed fit across RD40-130 and RD45-140 tandem roller variants, including DPF-equipped models, combination and offset drum configurations, and .3-generation updates.
- Vibration-Environment Rated — Used on compaction equipment that generates continuous drum vibration; OEM-spec hardware maintains correct clamp load and resists backing out under sustained dynamic loading.
- Direct OEM Cross-Reference — Part number 5100012595 maps directly to Wacker Neuson's parts catalog, so you can verify fitment against your machine serial number before ordering.
A countersunk screw provides a flush, low-profile fastening point where a raised screw head would interfere with adjacent components, mating surfaces, or operator clearances. On tandem rollers like the RD40-130 and RD45-140, hardware throughout the drum assembly, frame panels, and guard structures is subject to continuous vibration loads during compaction passes. Using the correct OEM fastener ensures the proper thread engagement and clamp force for the joint it was designed to secure. A stripped, undersized, or incorrect-grade screw in these locations can allow components to shift or loosen over time, leading to noise, misalignment, or damage to surrounding parts.
