Double Locking Nuts? - Structural engineering general ...

Silly question.....say you have a threaded rod hanger connection in which a threaded rod is supported by a glulam beam. The glulam beam would have a vertical hole drilled thru the CL of the beam width, the rod would be passed through and then hung with a nut and washer on top of the beam, (and probably a nut and washer below the beam to prevent upwards movement).

To prevent the rod from working itself loose, I was going to call up a double nut above and below the glulam. This would "lock" the connection right? I seem to recall that when you thread a single nut onto a threaded rod, tighten it to make the connection and then put a second nut and tighten it up snug to the first nut, the second nut would prevent the first nut from coming loose since they would tighten against each other???? I can't really visualize it in my head...maybe I should try it out for real!
