The Wacker Neuson Hex Screw is a genuine OEM hex screw designed for the RD40-130 and RD45-140 series tandem rollers, including standard, C, O, DPF, and.3 variants. As a direct OEM part, the is manufactured to the exact specifications used in original production, ensuring a correct, trouble-free installation every time. This screw covers an extensive range of RD-series configurations, making it a practical stocking item for fleet operators and service technicians running multiple roller variants. When it comes to fasteners in compaction equipment, using the right part matters — and the Wacker Neuson delivers exactly that.
Key Features
- OEM Thread and Dimensional Accuracy — Manufactured to exact pitch, length, and head spec so the fastener seats and torques correctly without risk of cross-threading or under-seating.
- Direct Drop-In Replacement — Installs in the same position as the original fastener with no rework, chasing, or re-tapping required on properly maintained housings.
- Broad RD-Series Compatibility — Fits RD40-130 and RD45-140 tandem rollers across standard, C, O, DPF, and .3 configurations, covering over 24 individual model variants.
- Correct Clamping Load — A properly spec'd fastener maintains the intended clamping force on mating components, preventing loosening under the continuous vibration loads typical of compaction equipment operation.
- Genuine Wacker Neuson Part — Sourced directly from Wacker Neuson, this is the same fastener used in original equipment assembly — not a generic substitute.
A hex screw is a threaded fastener used to clamp, secure, or retain components within the machine's assembly. In compaction equipment like tandem rollers, fasteners are subjected to constant vibration and dynamic load cycles, which place high demands on thread integrity and material strength. A worn, stripped, or incorrect screw can allow critical components to shift or come loose during operation, leading to premature wear on mating parts or, in more serious cases, mechanical failure that takes the machine out of service.
