Land Rover Defender: Screw Threads
- Damaged nuts, bolts and screws must always be discarded. Attempting to
recut or repair damaged threads with a
tap or die impairs the strength and fit of the threads and is not
recommended.
- Unless stated otherwise, self-locking nuts once removed must be
discarded and new nuts of the same type
strength grade installed.
NOTE:
During certain repair operations, it may be necessary to remove traces of thread
locking agents using a tap.
Where this is necessary, the instruction to do so will appear in the relevant
operation and it is essential that a
tap of the correct size and thread is used.
Where it is stated that bolts and screws may be re-used, the following
procedures must be carried out:
- Check that threads are undamaged.
- Remove all traces of locking agent from the threads.
CAUTION:
DO NOT use a wire brush; take care that threads are not damaged.
- make sure that threads are clean and free from oil or grease.
- Apply the specified locking agent to the bolt threads.
