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

works as well or better than loc-tite.

They used this were I used worked at the US Naval Ship Yard as an alternative to Loctite type products or Teflon Pipe Tape. I worked in he Diesel Shop and what had been happening is that when Pipe Tape was used on Screwed in Plugs on the Engines bits of the Pipe Tape sometimes would come off and end up some place in the Engine; in particular the Fuel System and cause grief. They started using this stuff to idiot proof the Job. Also Loctite type Products work but can sometimes be difficult to take apart. you spread it into the Threads and let it dry and it dries to a rubbery coating that seals and keeps stuff from coming loose. Once the Threads are coated you could put the un-used item on the shelf and come back years later and use it. Many Auto Part screwed in Plugs and Sensors come pre-coated with similar stuff. What ever you assemble with it will also dissemble easily later and the claim is you do not need to re-coat (you get a bout 3 uses without recoating). I have never tried that claim. But you can see the usefulness of that if you have a Mountain Bike or Skateboard that you need to take apart and re-assemble on the Road somewhere. The stuff is more expensive then Loctite type Products and not easy to find locally and then only at some exorbitant price. So that while it could entirely replace Loctite type Products I horde the tiny Bottle and use it only for special applications where Loctite is less likely to do a good job. This is a mundane example but I have an Electric Frying Pan that the Screws Vibrate that in use the handle Screws Vibrate out of. The Pan gets too hot for Loctite but the Vibri-tight works.

Easy to apply and will definitely keep your firearm screws and such from backing out. Would recommend over locktite as it doesn't dry brittle.

I've tossed two of the big bottle in the trash...learned my lesson. As others have stated, no matter how careful you are, be prepared to use pliers to open the jar on subsequent uses. You think you're going to screw the cap on very lightly....bad plan....that just lets more air in and ensures it'll go bad even sooner. It seems every time you open the jar you use up one of its lives. After about three lives, it's done the next time you open it, regardless of how much time has passed between usages (I've had it last months, only to try up within a week after being opened just one more time). I'm now using the 5ml tubes. much easier to stomach tossing one of those. Paying extra for them sucks, but it's literally the only way to use the product. Only buy the large bottle if you need to apply to fasteners in bulk in one sitting; if you intend to keep it on hand for multiple uses, the 5ml tubes are your best bet!

Absolutely love this stuff for screws on all of my firearms gear. I find this works so much better than blue loctite, so anything that has screws gets this. Accessories, optic mounts, flashlight mounts, anything. As long as you clean the threads after use and before you cap it back, I haven't had much issue with mess. You can cut the tip to be as small and precise as you want, and for my use of firearms equipment, it's enough to last for a while.

Saves on worms.used one all day .never lost one ..excellent item

Works better than LocTite on flipper knife pivots, you have to follow the directions to the letter, it's a little fiddley to work with but works wonders.

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.

Works good

It's good

This works exactly as it should. Those bolts never came loose again.

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.
