Drive shaft nut thread size

[HandyBob]

Hi all,
New here and would appreciate any help I can get.
The nut on my offside driveshaft somehow came loose over time and has cost me a new wheel bearing kit, to prevent this from happening again I want to replace both of the existing "standard" nuts with nyloc nuts, I've searched high and low to find the spec for the thread but I can't find it anywhere, is anyone able to shed some light on this for me please.
Thanks in advance.

If it's torqued up and split pinned it'll never come loose. It mustn't have been fully torqued up.

I have them come loose due to the action of the diff. I found that a Nissan Note 1.4 driveshaft nut fits just fine, and has nyloc.
