Randy, that's a good tip that I'm going to expound on a little. Blue Loc-tite is good stuff! However, you need to remember you generally put it on a steel thread going into aluminum. It's a good idea to use a steel nut of the appropriate size to "chase the threads" and clean the old hardened or cured Loc-tite off before you replace the screw or bolt. It's alot easier to do this than it is to get a hole that stripped out heli-arced, drilled and re-tapped.
