Blue Loctite on grip screws? Good idea or bad?

Hello all. I've got a Sig P220. I love it. I have added a set of Hogue grips and today at the range one of the grip screws came out. I put it back and tonight while I was cleaning it I noticed that all the Hogue (allen head) grip screws were a bit loose.

So, I was wondering if it would be a good idea to put a little blue loctite (the removable kind) on these? I figure that with the forces and torque exerted on these very small fasteners, it might be a good idea to use a little threadlocker on them so as not to lose them.

I know that over-torquing them can strip the threads so I don't want to tighten them too tight. So can anyone think of a reason not to use the loctite?

Go for it. The blue is good to use and can be removed. I put a little on scope mount screws to keep things tight.

If they are coming loose, then the blue stuff will work just fine - just don't go overboard

I use LocTite Purple on small screws on all my weapons. (scope mounts, bases, grips.etc.) Lower break point than Blue. Good on aluminum parts too.

I use it on my grip screws.

A tiny amount will be good. I use a toothpick to apply loctite to some screws.
Loctite is much better than torquing the screws harder because you could strip the threads in the aluminum frame.

Loctite 242 (blue) is probably the most widely used and is considered "removable" for threaded fasteners. Use it sparingly on small screws and you'll be fine. Good stuff.

My gunsmith's advice is to first touch the screw head with a soldering iron to warm-up the blue loctite before removing the screw.

Huh? It only "sets up" in the absence of air....it will remain liquid for days if just put on the screw without installing it.

Do you guys first clean with the Permatex Surface Prep activator?

The package for the purple threadlocker suggests doing so...but am wondering if this is really essential?

twofifty, I don't. I actually use the blue that is a paste. It comes in a large "chapstick" type set up.

Used blue Loctite on the grip screws on a Beretta M92---used a "bit" too much and glued the magazine into the pistol. The excess extruded into the mag well and.....could not figure out why the darn mag wouldn't drop as it was a couple of weeks between the gluing and the next time I used the pistol. Had to drive the magazine out with a dowell through the ejection port.
Pretty dumb but didn't even make my personal top ten list.

I have used blue loctite on my guns for 30+ years. If you control the amount you use, there shouldn't be a problem. It can prevent a lot of headaches when you are outside shooting someplace. Those little screws can be a real hassle to find in grass or dirt.

Unless they've changed since I tried them a few years ago, Hogue screws are made of too soft a metal IMO. I like TJ's screws better. They are harder and take a larger size of hex key. In combination with LocTite you may strip the heads out.

Right you are. Loctite is an anareobic adhesive.
