I have given 3 methods of checking torque. I don't see you offering a method to check torque

I have not offered one because there is no way to check torque short of being there while it is being done. [Linked Image]

Method 1:
He marks the position of the fastener, and using the proper tool applies torque to the lower limit.

If the fastener moves, he fails the job.

This does not check torque, this only ensure torque has been reached, it does not tell us if torque has been exceeded.

Quote
Method 2:

He requires a special inspection at the time of the installation.

I agree with Method 2

Quote
Method 3:

He requires a fastener where the head breaks off at the proper torque.

I agree this will work but the application is limited and it will be a problem if a you have disconnect and reconnect a conductor.
