The Wacker Neuson is a genuine OEM Hex Nut 1/4-28 UNF designed for the RD11AEC, RD11V, and RD11A hydrostatic double drum vibratory rollers. Sourced directly from Wacker Neuson, this fastener meets the exact thread specification and dimensional tolerances required for proper installation. It is a direct-fit replacement that installs without modification, maintaining the mechanical integrity of the assembly it secures. Confirm your model against the fitment list before ordering to ensure the correct part for your machine.
Key Features
- Correct Thread Form: — Manufactured to a 1/4-28 UNF fine-thread standard, ensuring full thread engagement and consistent clamping force in the fastened joint.
- Genuine OEM Part: — Supplied by Wacker Neuson as an authorized original component, meeting the same material grade and dimensional spec as the fastener installed at the factory.
- Verified Fitment: — Confirmed for the RD11AEC, RD11V, and RD11A hydrostatic double drum vibratory rollers, covering all three variants in the RD11 tandem roller family.
- Secure Joint Integrity: — A properly torqued fastener of the correct thread pitch prevents loosening under the sustained vibration loads that tandem rollers generate during compaction passes.
- Part Number Confidence: — Order part number 5000111337 directly to avoid cross-thread risk or fastener failure from using an incorrect-pitch substitute.
A hex nut is a threaded fastener that mates with a bolt or stud to clamp two or more components together. The 1/4-28 UNF designation refers to a fine-thread profile, which provides greater thread engagement per inch than a coarse-thread equivalent and is commonly used in assemblies subject to vibration. On a vibratory tandem roller like the RD11 series, maintaining correct fastener specification throughout the machine is critical — an incorrect thread pitch can strip during installation or back out under load, compromising the integrity of the assembly it holds and potentially leading to component damage or unsafe operation.
