The Wacker Neuson Stud Bolt is a genuine OEM stud bolt designed for the RD40-130 and RD45-140 series tandem rollers, including standard, C, O, DPF, and US variants. As a factory-sourced component, it carries the exact thread form, material grade, and dimensional spec required by the original assembly. Fitment spans a broad range of RD40-130 and RD45-140 configurations, making this the correct choice whether you're servicing a standard, canopy, open-ROPS, or DPF-equipped machine.
Key Features
- Genuine OEM Thread Integrity — Manufactured to the original Wacker Neuson specification, ensuring correct thread engagement and clamp load for a safety-critical fastener.
- Direct Drop-In Replacement — Matches the original stud bolt's thread pitch, shank diameter, and overall length so it seats and torques without rework or adaptation.
- Broad RD Series Fitment — Compatible with RD40-130 and RD45-140 tandem rollers across standard, C (canopy), O (open-ROPS), DPF, and US-spec variants, covering a wide production span.
- Maintains Clamping Performance — A correctly spec'd stud bolt holds critical assemblies at the designed clamping force; an undersized or incorrect fastener risks joint loosening under compaction vibration loads.
- Structural Safety Compliance — On roller equipment subject to continuous vibration, using the correct OEM-grade fastener is essential to maintain the structural integrity of bolted joints and meet safe operating standards.
A stud bolt is a fully threaded or partially threaded fastener that is anchored into a tapped hole at one end and secured with a nut at the other, creating a strong, reusable joint between two components. On tandem rollers like the RD40-130 and RD45-140, stud bolts are used in high-vibration environments where reliable, repeatable clamping is critical to keeping assemblies secure during operation. When a stud bolt stretches, strips, or corrodes, the joint it holds can loosen progressively, leading to component movement, accelerated wear, and potential structural failure — replacing it promptly with the correct OEM part restores the joint to its designed specification.
