Default Screws with pre-applied loctite ... HELP!

How do you get this stuff off the screw?

I have some torx screws with some factory pre-applied gummy yellow loctite like material them. I know that this is supposed to make the screw less likely to back out. However, all it does is make it hard to insert the screw in the mount.

Anyone know how to clean the screw and get this stuff off?

Wire brush or wire wheel. You could run it through something else then install in what you really want to.
Even a razor knife around the treads would work.

Careful with fire if high strength bolt- easy to overheat small part and mess up temper. Acetone and brass brush is best. Don't use ss brush if its an ss screw. Easily may gall when you screw it in

You could chase the threads with a razor blade and pick off as much as you can.

If you want to do it proper then Loctite 76820 solvent is what you want.

Soak or wipe using acetone?
Loctite will soften with a soak, but not just wipe away.

A hot knife with an X-Acto blade will cut through enough of it.

you could try slowly easing it into the threads... screw it in a little bit, then back it out a bit, then in a little more and back out again, etc...

what are the screws for?

Agreed
This is why we keep extra screws around. You can get batches of "gun smithing" screws from Brownies/Midway on line gun parts retailer du jour.

Just chase them with a nut of the same size, or just screw them in and out of the mounting plate without what ever you are mounting. Should clean them right up.

It's ok that it's hard to install.
If you don't have tools/skills enough to install the screws with the thread adhesive on them, you probably should not be messing with them at all.

Why don't you want to use it?

It's suppose to be more difficult than bare threads to install....that's What keeps it from backing out when recoil occurs.

I love the "just burn it off" or "use a torch" suggestions. Scope screws are already low strength without making them worse. So now you have burnt, hardened material stuck on the screw and for sure won't be able to screw them in without damage.

Order a new set from mfr.

As funny as this may sound I believe the majority of those compounds are actually there for two reasons, One is to aid in the screw not backing out and two it keeps the screw from galling when you install it. Removing it would be the last thing you should do. You have to remember a lot of these screws go into different metals and when dissimilar metals make contact corrosion happens between the parts and creates issues as well. I have had much better luck leaving that stuff on than using screws without it.

Impact gun will help get it in. Make sure the optic is mounted exactly where you want, kink the screw about 15 degrees off angle, and pin that trigger back and enjoy the show.

No, please don't do that. You should be able to thread the screw on with a slight amount of effort. Just make sure you aren't cross threading it.
