Checking torque on screws that have thread locker?

[KRN123060]

So if I use Loctite or similar on the optic mounted on my pistol will checking that by applying torque (like using an allen wrench) wreck the bond? Is it best to leave as is until it is noticeably loose or will just a bit of pressure be ok? I think I have things torqued to spec but I don't want my optic flying off my 10mm. LOL.

It would seem like if you originally torqued them to 15 inch pounds with the locker acting as lube, when the locker hardens 15 lbs wouldn’t break loose. On the other hand I’m not sure why you would need to check them if you used the proper lock.

Leave 'em be. The breakaway torque is higher than the persistent torque of cured threadlocker.

If you doubt the fasteners' clamping force... remove, clean thoroughly (physically & chemically), and reinstall.
If they came loose re-tightening won't keep 'em there, so same advice.

Mark the fastener so you can see if it moves... but do a better job than the person that did this.

Drill them and safety wire them.

Or put the optic in a vise, and use a sledge and chisel and punch the sides of the optic in to stake the screws.

ETA why won’t anyone buy my guns?

Torque 'em to spec and don't worry about it.

Break the already dried thread locker?

Guess I was pretty close. Although as proficient as they seem to be with snatching open carry I would have thought they would be more proficient?

Must have been faster than me! I could never beat a car when I tried racing one.
