Frequently asked questions

What is the 50525 lock nut used for?
This is a 5/16 BSF self-locking nut fitted on the transmission parking-brake assembly. It retains the transmission (handbrake) brake drum, with its self-locking thread resisting loosening from drivetrain vibration and rotation.
Which Land Rover models use this lock nut?
It's listed for the Land Rover Series II and III. Confirm your parking brake setup uses the transmission-mounted drum brake before ordering, as later models moved away from this arrangement.
Can this lock nut be reused, or does it need replacing?
Self-locking nuts like this are typically single-use. Once removed, the locking thread has usually deformed and lost its resistance to loosening, so it's best practice to fit a new one whenever the drum is removed.
How many of these lock nuts are needed for the job?
Just one. It's the single retaining nut for the transmission handbrake drum, so no other lock nuts are needed for this specific job.
