The Wacker Neuson Stud Screw is a genuine OEM component designed for the RD40-130 and RD45-140 series tandem rollers. Sourced directly from Wacker Neuson, this stud screw meets the same specifications as the original hardware installed at the factory, ensuring a consistent, accurate fit every time. Compatibility spans the full RD40-130 and RD45-140 model families, including standard, C, O, US, DPF, and.3 variants across multiple build series.
Key Features
- Genuine OEM Threading Integrity — Manufactured to the original thread pitch and shank dimensions, so the stud seats and torques correctly without risk of cross-threading or misalignment.
- Direct Drop-In Replacement — Matches the original stud screw installation point exactly, replacing part number 5100039072 with no rework or adaptation to the host assembly.
- Broad RD-Series Fitment — Confirmed for the complete RD40-130 and RD45-140 model families, covering standard, C, O, US, DPF, and .3 build configurations across all listed serial series.
- Maintains Clamping Load — A correctly specified stud screw holds the mating components at the designed clamping force; a worn or wrong-spec fastener can lead to loosening, vibration damage, or component separation during operation.
- OEM Part Number Verified — Carries the Wacker Neuson part number 5100039072, eliminating guesswork when cross-referencing your machine's parts manual.
A stud screw is a headless fastener threaded on one or both ends, used to create a fixed anchor point in a housing or structural member so that a mating component can be secured with a nut. On tandem rollers like the RD40-130 and RD45-140, stud screws are commonly used in high-vibration assemblies where a standard bolt-and-nut configuration would be impractical to service. When a stud screw becomes stripped, corroded, or sheared, the component it anchors can shift or detach, compromising machine integrity and potentially causing further damage to surrounding parts. Replacing a failed stud screw promptly with the correct OEM part restores the designed holding strength and keeps the assembly performing as intended.
