LocTite won't hurt anything - but have several grades for various applications (I use #222, #242, and #272 as a general rule.)
If you're going to use never-seez, MAKE SURE TO LOWER INSTALLATION TORQUE BY HALF! If you don't, you actually run a risk of snapping the bolt, and you've got better than half chances of deforming it.
"Bolt Torque" is actually used (as an estimate) to measure preload, or "stretch" of a bolt on installation. This is measured by the resistance to turning that a bolt experiences as the threads get wedged together.
Decreasing the friction between the surfaces will actually INCREASE both compressive loads and bolt deformation on installation - and it may increase the bolt deformation beyond the "elastic limit" - the point at which the metal will recover its original shape. This results in permanent bolt deformation, and premature failure.
Now, if the torque spec calls for some sort of lubricant, USE THAT LUBRICANT. If it calls for "clean, dry" threads, here are the modification factors:
LocTite - None
Engine Oil - lower by a third
Never-Seez - lower by half
My apologies to anyone who already knows this, and I'm just trying to make sure those of you who DON'T know this already don't go breaking parts or hardware...
