Liquidorange, My friend I hope you're kidding about using Red LocTite #262.If you did you won't turn it no matter what you use.That is some powerful stuff.You should have used the Blue LT #242 if you were going to use any.Not being smart I wish you luck trying to adjust that sight. A screw that small with Red LT is vertually impossible to remove.I use the LT's at work. I've seen first hand how that stuff works.Red's so strong it's scary.About the only way to break it loose is apply quite a bit of heat. I doubt that would even work on a tiny screw.
