The Wacker Neuson is a genuine OEM Screw With Washer 5X10 designed for the RD12A-90 tandem roller and CRT36-26A ride-on concrete trowel series. Sourced directly from Wacker Neuson, this fastener assembly delivers the exact dimensions, thread specification, and integrated washer profile required by the original design. Part number is confirmed for multiple configurations across both machine families, including standard, foldable ROPS, and wheel kit variants. Choosing a genuine OEM fastener means the integrated washer seats and clamps exactly as the assembly was engineered to perform.
Key Features
- Exact Thread and Washer Integration — The captured washer is sized and hardened to match the clamping load requirements of the original fastener point, preventing surface damage and fastener backing out under vibration.
- Genuine OEM Sourcing — Produced to the same specification as the fastener installed at the factory, ensuring correct torque take-up and material grade for the application.
- Broad Fitment Across Two Machine Families — Confirmed for the RD12A-90 tandem roller (including standard, green drum, and foldable ROPS builds) and the CRT36-26A and CRTv36-26A ride-on trowel series.
- Vibration Resistance — The integrated washer design distributes clamp load evenly, reducing the risk of loosening caused by the continuous vibration inherent in both roller and trowel operation.
- Direct Hardware Replacement — Matches the original 5X10 sizing exactly, allowing installation without drilling, tapping, or substituting non-specified fasteners that could compromise joint integrity.
A screw with integrated washer is a captive fastener assembly where the washer is permanently retained on the screw shank, keeping both components together as a single unit during installation. This design ensures the washer cannot be omitted, misaligned, or lost during assembly or service — important on machines where access is limited or components are reassembled frequently in the field. When the correct fastener is not used, or when a worn example is reused, the joint can lose clamping force over time, leading to loosened panels, misaligned guards, or structural fastener points that develop movement under load.
