⚙️ Key Features
- Genuine Volvo Penta Retaining Nut - part number 20861068
- Exact thread diameter and pitch
- Specified strength class
- Correct bearing face and overall height

- Provides full thread engagement on the original stud/bolt
- Tighten to the specified torque and replace if prevailing-locking action is lost

🔌 Function
The nut converts tightening torque into axial clamp load on the joint. Correct thread fit and bearing geometry allow that preload to remain stable through vibration and temperature changes.
⚠️ Common Signs of Failure
- Thread stripping or galling
- Rounded flats prevent correct tightening
- Nut backs off under vibration
- Corrosion changes the thread fit
- Incorrect height or grade reduces thread engagement
🛠️ Service Notes
- Fit a new nut wherever the original is a self-locking, nylon-insert or deformed-thread type — the locking feature is single-use and a reused one will not hold
- Clean and inspect the male thread before fitting; run the nut down by hand for most of its travel, and stop and investigate rather than forcing a nut that binds
- Tighten to the figure given in the workshop manual for your engine, using the correct washer and the specified tightening sequence where one applies
- Renew any split pin, tab washer, locking wire or lock washer that goes with the nut, and bend or fit the locking device properly once tightened
- On drive and underwater assemblies, keep dissimilar metals apart where the design intends it and refit any anti-corrosion or anti-seize treatment the manual specifies for that joint
