Vibra-TITE 213 VC-3 Threadmate Threadlocker, -65 to 165 Degree F, 5mL Tube, Red

Way better than blue loctite. Clean your fasteners before use. Apply to threads. Let cure for 30 minutes prior to installation. We use on all out club firearms and air guns, as well as archery equipment.

Was having trouble with stuff backing out with blue lot tite and this is pretty commonly recommended for handgun optics. So far I have had zero issues and all is great. Easy to use.

Strong stuff works as advertised Note, avoid putting on bolts that your use hand tools to tighten, because it really increases difficulty of tightening fasteners Better suited in conjunction with pneumatic or battery operating tools

Awesome stuff. Always have this around when using a normal threadlocker isnt a option. Great for guns, RC cars, very small screws etc.. Not for high temp environments but good fod everything else. Been buying this fod years and will continue to do so.

Worked well on my pistol optic and shotgun stock screw. Before Vibratite, I was using the usual loctite blue but that did not stand the vibrations and jolts caused by a 10mm pistol and 12 gauge high brass shotgun loads. So my optic came slightly loose and lost its zero and my semi automatic shotgun had its stock loosen after 100+ shells shot. I then tried out the vibratite on both my firearms and went back to the range at least three times to confirm that it works and is better than loctite blue. It is confirmed. 10mm pistol optic holding zero perfectly now with no evidence that the thread locker is failing. Same with the shotgun, with the stock being firmly set and secure with no evidence of it coming loose. So, vibratite is good for firearm purposes

Great threadlocker , this brand is what you need for good results for sealing threads

I love my Smith & Wesson SW22 Victory .22 pistol, but from day one I was unable to keep the takedown screw from loosening after 50-100 rounds. That screw is a major design flaw in the Victory, and I had resigned myself to stopping after every 50 rounds to tighten it. Then I came across a suggestion on the S&W forum to try this Vibra-TITE thread locker, so I ordered a tube here on Amazon. This is truly the answer to the Victory's takedown screw. I covered about half the screw's threads with this stuff, waited 15 minutes, then put the gun back together. I went to the range and ran 200 rounds through it and that takedown screw never moved. Here's the problem with the Victory's takedown screw as I see it. When you insert that screw and begin tightening it, it offers no resistance whatsoever until it reaches its final 1/8th turn or so. Because of that lack of early resistance during the tightening process, if it loosens even a tiny bit during a shooting session there is no resistance to keep it from unscrewing itself. Enter the Vibra-TITE thread locker. With this stuff on the threads, there is instant resistance when you go to tighten the screw. You can feel the resistance, and you just know that screw is not going to easily come loose. And just one application is good for several shooting and cleaning sessions; you don't have to reapply it after every removal of the screw. It is the perfect fix for the SW22 Victory's poorly-designed takedown screw, and I highly recommend it for that purpose.

This product is good for my pistol red dot optic. It does not harden like the lock tite does. It does keep the screws from backing out from the impacts of the slide. I still check them but have not had them back out since using this product.

It's good

Small quantities, only air in the tube

This product makes bolts & nuts secure from loosening against vibrations. It is easy to put appart and reuse not more than twice.

Pricey but good stuff

Works well for screws on things like snowboard bindings because it keeps them tight and doesn't react with gear like loctite does.
