The only problem it solved was one of the ones I am having. I have a 1.2" bull barrel taken from a 700 action. I threaded it for a Savage and installed it. Problem is, I can't get a normal wrench over and down the barrel, so the nut is only hand tight with a strap wrench. I was gonna cut 60% of my nut wrench away, so I could slide it over, but this nut solves the problem.

David; the joke you are missing is that torque is measured in foot pounds or newton meters, not psi.
Sorry I ruined that for ya Phil :-)
