Prevailing Torque "Stover" Nut?
Prevailing Torque "Stover" Nut?
(OP)
I am considering using a 1 1/4" nylon lock nut for my application, however, due to thread engagement limitation I would like to consider the Prevailing torque nut. I am unfamiliar with this style of nut. Can anyone provide input on how well it works?

A "Stover" nut is also known as a Top Lock. You can see an image here:

I figured that the stover nut did not require the same thickness than a nylock, since it did not have the 1/4" thick nylon portion on the top face...Do you know whether it has better or worse breaking torque than the nylock?
Are you suggesting that these type of nuts only be used for temporary installation?

These nuts can be used for permanent installation. The caveat is that the prevailing torque feature does not prevent joint preload loss, which is the main consideration for joint performance.
