The Wacker Neuson Counternut is a genuine OEM component designed for RD7H series walk-behind tandem rollers and DPU series reversible vibratory plate compactors. As a direct OEM replacement, this counternut is manufactured to the same specification as the original part — ensuring correct torque retention and thread engagement when installed. Fitment spans a broad range of Wacker Neuson equipment including RD7H and RD7He tandem rollers and DPU 4045H, DPU 4545H, DPU 5045H, DPU 5545H, DPU 6055, and DPU 6555H reversible vibratory plates. Sourcing the correct counternut by part number is the fastest way to confirm you have the right hardware for the job.
Key Features
- Genuine OEM Thread Integrity — Manufactured to exact Wacker Neuson specifications, this counternut delivers the correct thread pitch and hardness grade needed to maintain secure, vibration-resistant fastening in high-cycle compaction equipment.
- Drop-In Hardware Replacement — Dimensionally identical to the original, this counternut installs directly onto existing studs or threaded shafts with no rework to mating components.
- Broad Fitment Across Two Machine Families — Verified for RD7H and RD7He tandem rollers and the full DPU 4045H through DPU 6555H reversible vibratory plate range, covering both diesel and hybrid configurations.
- Vibration-Resistant Locking Function — A counternut is specifically designed to resist loosening under sustained mechanical vibration — the operating environment these machines produce continuously. A worn or missing counternut can allow critical fastener assemblies to back off during operation.
- Genuine Part Traceability — Sourced directly through the Wacker Neuson OEM supply chain under part number 5000207587, giving you full confidence in material provenance and part authenticity.
A counternut — sometimes called a jam nut or lock nut — threads against a primary nut or along a threaded shaft to prevent the fastener assembly from loosening under load. In vibratory compaction equipment and tandem rollers, where continuous oscillation is the normal working condition, standard nuts alone can gradually back off over time; the counternut applies opposing clamping force that locks the assembly in place. When a counternut wears, strips, or goes missing, the associated fastener can lose tension, leading to component movement, accelerated wear on mating parts, or mechanical failure during operation.
