Loctite - Yes or No???

Post by Macross » 18 Nov 2019, 8:28 pm

I have a couple of screws that hold the rear sight plate on my optic ready shadow 2 that have been backing out during range sessions. This causes the rear sight plate to wiggle a bit. I have hand tightened to a point that im not wanting to go further for fear of stripping the threads out. but given a few range trips, they start to back out again and aim starts to wander with wiggly rear sight.

Is this something that requires a few drops of Loctite. Or is that not recommended. I have asked a few people and currently the count seems pretty evenly split between the yea and nay. Any thoughts or suggestions... If Loctite, is it just a few drops of the Blue thread locker????

Yes, I am in the blue camp.
Virtually all sight screws on my handguns are done with blue loctite.

I have used Loctite 243 for rings etc, which I believe is about midrange as far as strength goes. Although it takes a little more effort, screws can still be undone if needed. I am still unsure if there is any advantage to it mate. I know plenty of people who don’t use it and haven’t had any issues.

Another option is to do up your screws as tight as you are game then put a little dab of clear nail polish on them. I believe that this process is often used with eye glasses to stop screws coming loose and losing them.

Easy to remove with acetone/nail polish remover

Yes from me. I degrease the threads best I can, then put a small amount on.
