The set screw that holds the drift adjustable sight on my newly purchased Kimber handgun is locktighted and won't budge. I've tried heat (transferred via a cut off hex wrench) but no go. Am soaking with Kroil overnight. Problem is it's a very small screw and I worry about stripping out the socked so can't apply much tork. And advice as to what next is appreciated.
It's probably going to take more heat that what you were able to transfer through the hex wrench. Unless the sight is plastic, tritium, or, something fragile, apply a propane torch directly to the sight and get it warm. Use a jewelers screw driver and a pair of pliers if needed to break the grip of the loctite. Usually though, the propane is enough to "git 'r done".

Direct heat from a soldering iron would probably be the way to go. I've never needed a soldering iron to remove any screws but if the occasion ever called for it, I would certainly give it a shot.
Tried heat, small torch and soldering iron, (truitium sight prevents excessive heat) penetrating oil, fingernail polish remover and swearing. Nada. Back to Kimber with note to remove and return sans loctight.

Unfortunately, sometimes the only thing that will break the locktite is the heat from a drill bit.
