What color Loc-tite for sights?

aarondhgraham · November 28, 2011, 12:58 PM

I went to their website and it looks like the Blue is best for use on adjustable sight screws.

Is this correct?

Unless you want it there permanently, don't use red. Blue is the common choice to lock screws that will be removed with hand tools; green is similar to blue, but will penetrate and lock screws already installed.

Blue it is then.

Be sure you get Blue 242. I’ve been told, for what that’s worth, that there are different strength’s in blue. Haven’t seen it myself, but 242 is the one you need.

Sometimes confusing, my blue LocTite came in a red plastic bottle.

I use clear nail polish with great success.

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.

I use Loctite on scope mount screws.

242 comes in a red container, and the liquid is blue.

I don't like calling it "blue".
I can't see the color when I go to get it, just the container.

Cleaning mount male screws is easy.
Cleaning mount female threads in the receiver is hard, if they go all the way through to the greased up barrel threads.

I have a few hundred beat up old gun amateur gunsmithing projects.

When I go to the range, I have tools and help other guys with their problems.

Fully 50% of my problems and everyone else's problem is loose scope mount screws.

Look for two holes touching over here, followed by two holes touching way over there.

I know another old guy I helped move, and he has as many tons of guns stuff and I do. He has never had a loose scope mount screw, and does not use Loctite on his guns.

Maybe he is in denial. Maybe he is doing something right that I am doing wrong.

But with guns I will hunt with, I take off the barrel, so I can get those scope mount female threads squeaky clean before I put Loctite in there.

And I fixture and glass bed under the scope mounts.
