The Wacker Neuson Screw With Washer 4X8 is a genuine OEM component designed for the RD12A-90 Tandem Roller series and CRT36-26A and CRTv36-26A Trowel series. Sourced directly from Wacker Neuson, this fastener assembly is manufactured to the exact dimensions and material specifications of the original hardware. Whether you're servicing a double drum roller or a ride-on trowel, part delivers a correct, consistent fit across all covered configurations — including foldable ROPS and wheel kit variants.
Key Features
- Integrated Washer Construction — The captive washer is factory-formed as part of the fastener, ensuring consistent clamping load and eliminating the risk of a lost or misaligned washer during installation.
- Genuine OEM Material Grade — Manufactured to Wacker Neuson's specified thread pitch, head geometry, and material hardness so torque values and holding strength match the original design intent.
- Drop-In Installation — Matches the original thread form and head drive style exactly, threading directly into existing bosses and mounting points without reworking or adapting surrounding hardware.
- Broad Model Coverage — Fits the RD12A-90 Tandem Roller range and the CRT36-26A and CRTv36-26A Trowel range, covering standard, foldable ROPS, and wheel kit configurations under a single part number.
- Structural Integrity Maintained — A worn or under-spec fastener in high-vibration equipment like compaction rollers and ride-on trowels can lead to loosening, misalignment, or panel and guard failures; using the correct OEM hardware keeps assemblies secure under working loads.
A screw with washer is a combined fastener used to secure panels, guards, covers, and structural components throughout the machine. The integrated washer distributes clamping force across a wider surface area, preventing the fastener from pulling through softer substrates or causing surface damage around the mounting hole. In high-vibration equipment like compaction rollers and power trowels, maintaining the correct fastener hardware is essential — a failed or missing fastener can allow guards and covers to shift or detach, compromising both machine performance and operator safety.
