Capped nuts are used
- prevent overtightening due to the threaded portion being restricted by the cap.
- to provide a dry torque joint.
- to stop leaks.
Explanation
A capped (acorn/dome) nut has a closed top that seals the thread end, so it is used to stop fluid leaking past the exposed thread and to protect the protruding bolt end. It does not provide a dry-torque joint or assure dry bolting.
