They should only be torqued "snug". Do not try to get them "real tight". Screws vibrate loose. The Loctite keeps them from vibrating loose. DO NOT USE RED LOCTITE. USE THE BLUE LOCTITE. If you use the red Loctite, you'll have the devil of a time ever removing them. Red is basically a permanent epoxy. Blue is for studs, bolts, etc. to keep them from vibrating loose. Too many garage gunsmiths think you need to crank the snot out of the screws to keep them from coming loose. You don't. Remember, snug and blue loctite. I've never had one come loose yet and I've done hundreds of scope mounts over the years (I'm really old). Have fun.
