The Wacker Neuson is a genuine OEM Bolt 7/16-20 designed for the RD27-100 and RD27-120 hydrostatic vibratory rollers. As a factory-sourced component, this bolt is manufactured to the exact thread pitch, grade, and dimensional specification required by the RD27 series. It services the full RD27 lineup, including standard and traction control variants across all known machine configurations. When hardware fails or goes missing during field service, fitting the correct OEM replacement keeps the machine structurally sound and ready for asphalt and soil compaction work.
Key Features
- Correct Thread Specification: — Cut to a 7/16-20 UNF thread profile, matching the torque and clamping requirements of the original fastener position on RD27-series rollers.
- Genuine OEM Sourcing: — Supplied directly from Wacker Neuson, ensuring the bolt meets the same material grade and tensile strength as the part it replaces.
- Broad RD27 Fitment: — Compatible with RD27-100 and RD27-120 rollers in standard and traction control configurations, covering a wide range of machine numbers within the RD27 family.
- Drop-In Hardware Replacement: — Threads directly into the existing fastener location without reworking or re-tapping, keeping service time short.
- Structural Integrity Where It Counts: — A correctly torqued, properly graded bolt maintains clamping force at critical joints; an incorrect or worn fastener risks loosening under the vibration loads characteristic of compaction equipment.
A bolt in a vibratory roller carries more than just static load — it must maintain clamping force through continuous vibration cycles, directional changes, and the mechanical stress of drum compaction. Using a fastener with the correct thread pitch and material grade ensures that joints stay tight and aligned throughout the roller's operating life. When a bolt stretches, strips, or is replaced with an incorrect grade, clamping force drops, and the components it secures can shift or wear prematurely.
