The Wacker Neuson Stud Bolt is a genuine OEM stud bolt designed for the RD24-100, RD27-120, RD40-130, and RD45-140 series tandem rollers. As a direct factory replacement, this part meets the original manufacturer's specifications, ensuring correct thread engagement and secure fastening wherever it is installed on your machine. Wacker Neuson's genuine OEM designation means this stud bolt is sourced and validated for these roller families, covering a wide range of standard, canopy, and open-frame variants across multiple build series.
Key Features
- OEM Thread Integrity — Manufactured to exact thread pitch and shank dimensions, so the bolt seats and torques correctly without risk of cross-threading or premature stripping.
- Direct Drop-In Replacement — Matches the original mounting configuration, allowing installation without re-drilling or re-tapping existing fastener points.
- Broad Tandem Roller Coverage — Fits RD24-100, RD27-120, RD28-120, RD40-130, and RD45-140 series machines, including standard, canopy (C), and open-frame (O) variants across multiple build generations.
- Structural Fastening Confidence — A correctly torqued stud bolt maintains component clamping loads under the constant vibration of compaction work; a worn or incorrect bolt risks joint loosening and component damage over time.
- Genuine Wacker Neuson Part — Sourced directly through Wacker Neuson's OEM supply chain, so you can verify part number 5100012894 against your machine's parts manual with confidence.
A stud bolt is a fully threaded or partially threaded fastener used to clamp two or more components together, typically by accepting a nut on one or both ends rather than using a bolt head. On tandem rollers, stud bolts appear in high-load assemblies where consistent clamping force must be maintained through continuous vibration and drum rotation. When a stud bolt stretches, corrodes, or fails, the joint it secures can shift or work loose, leading to accelerated wear on surrounding components and potential structural failure if left unaddressed. Replacing a damaged stud bolt promptly with a correctly specified OEM part restores the clamping integrity the assembly was engineered around.
