Measurement Question

This is a question that can likely be answered outside of the world of drums, but I know I'll get the right answer from y'all.

When measuring the length of a tension rod, should you measure the entire length of the rod? From under the head to the end of the shaft? Or just the threaded portion?

I'm replacing some Pearl tension rods and want to make sure my rods are uniform.

Not sure about drum tension rods specifically, but in general a bolt is measured from under the head to the end.
