I have a screw loose...

[WMDShooter]

The front sight screw on my Ruger .22 Mark III Competition keeps working loose. Can anyone offer a tip on how to keep it tight, i.e. is there a recommended adhesive for handguns? Thank you for the help...

I was about to recommend a shrink,,,but like they said Loctite 242 or 243 should do it.

Take it to a high school welding class. They'll do it for free.

I've seen some of the beads that get laid in some HS classes, I'd take the duct tape first.

Blue loc-tite.

No way to fix it. Gun is trashed. I'll dispose of it for you.

I prefer Green for this application. Blue will work loose with moderate heat generated from firing.

I have tightened hundreds of MK Series Front AND Rear Sights. Green is where its at.

Red too much?

Red too much?

Red will work but it dosent work on loose dovetails as well as green does. I use the green on the Rear Sight because the Dovetails are often oversized. Many people dont want me to tighten the dovetail so I use this method.

My mechanic says I have a loose nut behind the wheel.

I would not recommend taking any firearm or part to a school... That could end up badly.

blue works...just make sure you use brake cleaner on the screw to clean off the grease/oil and let it dry before applying the loctite.

I used blue on my AK pinned muzzle break...hasnt come loose yet....thousands of rds fired through it...maybe i just got lucky with it...as it came loose when I first bought it...

I don't know what the loc-tite is going on, but I understand that Green is wicking. Designed to be placed on press fit pins and such. Blue is for small threads (removable) and red is not removable(requires heat)

Any comments, I am shooting off the top of my head.

The colour is very important. Red loctite is permanent - blue is very good hold but not permanent.

Actually fastner size plays a role in which loctite to use. Purple is low strength, and is used on small tiny screws (like scope mounts) it will come loose without heat-and just regular handtools. I prefer this for scope mounting -both rings and base. Too strong of a loctite - and the screws will strip the heads, unless you heat them first.

Blue is a low strength, and used for larger fasters , that do not require permanent locking. Fastners should loosen with just handtools, unless they are real small micro screws -then you may have a problem.

Red is intended for permanent locking. You WILL need heat to get a fastener loose with loctite red on it. Usally loctite red is used for critical engine parts, like connecting rod cap bolts.

There is also a loctite orange -which is a flange sealer. We used to use a monster sized tube of that stuff, for the air cooled Porsche 911 motors - they require it for the engine case halves, and the cam housings to all 6 cylinder heads. You apply it with a paint roller - literally.

Loctite green is penetrative/wicking -for use without disassembling the fastner.

There are probably a lot more loctites out there...

I've had the same trouble with my MKIII Target. Last time I went to the range I went to reload through the course of the day and found my sight 90 degrees from straight. Shot pretty well before that though...
