The Wacker Neuson is a genuine OEM Hex Nut, Slotted, 7/16-20 designed for the RD12A-90, RD12-90, and RD11 series walk-behind tandem rollers. Sourced directly through Wacker Neuson's authorized parts program, this fastener matches the exact thread specification and slot configuration called out in the original equipment design. It fits across multiple RD12 and RD11 configurations, including standard, foldable ROPS, and hydrostatic double-drum vibratory roller variants. When you need a direct replacement that installs without guesswork, part number is the correct choice.
Key Features
- Correct Thread Specification: — Cut to a 7/16-20 fine thread pitch, matching the original fastener spec for a secure, properly torqued connection.
- Slotted Design for Positive Locking: — The slotted hex profile accepts a cotter pin or safety wire, preventing loosening under the continuous vibration loads typical of tandem roller operation.
- Genuine OEM Part: — Manufactured to Wacker Neuson's original material and dimensional standards, ensuring the nut performs as intended within the machine's fastener system.
- Broad RD Series Compatibility: — Confirmed fitment across RD12A-90, RD12-90, and RD11A/RD11V tandem rollers, covering standard solid ROPS, foldable ROPS, and hydrostatic double-drum configurations.
- Maintains Drivetrain and Assembly Integrity: — A worn, stripped, or incorrect nut in a high-vibration assembly can lead to joint failure or component displacement; using the correct OEM fastener keeps critical assemblies secure through demanding compaction cycles.
A slotted hex nut is a precision fastener used in applications where a connection must be both tightly torqued and positively locked against loosening. The slotted crown allows a cotter pin or safety wire to pass through a corresponding hole in the bolt or shaft, mechanically preventing the nut from backing off during operation. On a tandem roller like the RD12 or RD11 series, continuous vibration from the drum exciter system places constant stress on every fastened joint — a standard nut can work loose over time, but a slotted nut with a cotter pin cannot rotate freely once locked. A missing, damaged, or wrong-specification nut in these locations risks joint separation, component movement, or accelerated wear on surrounding hardware.
