The Wacker Neuson is a genuine OEM Locknut M10 X 1.5 designed for the RD27-100 and RD27-120 series hydrostatic vibratory tandem rollers. As a direct factory part, the meets the exact thread pitch and dimensional specifications required for a secure, rattle-free installation. Wacker Neuson genuine OEM hardware ensures correct torque retention across the demanding vibration loads these machines generate during asphalt and soil compaction work. If you are servicing an RD27-100 or RD27-120 roller, this is the correct OEM locking fastener to specify.
Key Features
- M10 X 1.5 Thread Specification: — Manufactured to the exact thread pitch and engagement depth required by Wacker Neuson's engineering tolerances, ensuring full thread contact and rated clamping load.
- Vibration-Resistant Locking Design: — The prevailing-torque locking feature resists loosening under the continuous vibratory forces generated by tandem roller operation, maintaining fastener integrity over time.
- Genuine OEM Hardware: — Sourced directly through Wacker Neuson's OEM supply chain, this locknut matches the original material grade and surface treatment specified for the RD27 roller family.
- Confirmed Fitment for RD27 Tandem Rollers: — Verified for use on RD27-100 and RD27-120 hydrostatic vibratory tandem rollers, covering multiple machine configurations in both series.
- Drop-In Fastener Replacement: — Installs directly onto existing M10 X 1.5 threaded studs and bolts with no modification to surrounding hardware or mating components.
A locknut is a prevailing-torque fastener engineered to resist loosening under vibration and dynamic loading — exactly the conditions present on a hydrostatic vibratory tandem roller. Unlike a standard nut, the locking feature maintains clamping force even as the machine cycles through compaction passes, protecting the integrity of the assembly it secures. When a locknut loses its locking effectiveness or is reused past its service life, fastener loosening can allow connected components to shift, accelerating wear and potentially leading to more significant mechanical issues.
