Loctite
Having used about a one half pint of Red Loctite and a pint of Blue Loctite in my 40 yrs of working before I retired. I can probably give you some tips.
First degrease everything, CLEAN the threads of the hole and the screw threads, then check them make sure there is no grease in the threads. Brake cleaner is good, then let everything dry, dry holes with q-tip. Put your loctite on the screw and run in the hole, then remove the screw, adjust everything, then assemble. Double check adjustment. Wipe off any exess around screw heads. If you have to remove a screw that has been BLUE loctited, take a screwdriver that fits the screw head, heat with a cigarette lighter, put into the slot for 30 seconds, remove and use a proper screw driver to remove the screw while warm. Clean out the old loctite from hole and screw threads before trying to reinstall.
If you use red loctite get yourself a propane torch, heat a screwdriver VERY hot but not red hot, put it into the slot for 30 seconds then use the correct screwdriver to remove.
Warming the screws after everything is installed and adjusted will make it set up quicker. Loctite sets up in the absence of air, so make sure you are properly adjusted the first time, the second time is a clean up job and start from scratch you won't like. Let the loctite set for about 12 hours after assembly before handling. Just an old fart's two cents worth.
