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

After reading some reviews and with the recommendation of a couple of g-nsmiths, I decided to try this. I've yet to use it on a fire arm or optics, but I've used it on some outdoor power tools and on a wood chipper/shredder where the manufacturer recommended "blue" thread locker. This seems to work better. There is a delay since you'll have to wait for the product to dry before assembly. Then it somewhat feels like you're using nylon lock nuts when you're threading the nuts on. There's definitely resistance there. So far it seems to hold the nuts and bolts in place. There hasn't been a change in torque values (for the fasteners that have such requirements).

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 have used every kind of thread locker over the past 30 years, as a master race engine builder, machinist, and gunsmith. For many purposes I would use this over anything else without question! Not as messy as the other top brands, it can put it on fasteners and let it sit and install later, it can be applied to fasteners that will be taken out and reinstalled multiple times and still work great!

I use this for my collection of (cheap) reading glasses, which have tiny screws holding the arms in, which screws keep wanting to loosen themselves, fall out, and disappear; unless I tighten the screws, constantly.The Vibra-TITE 213 VC-3 Threadmate Threadlocker product does the job. Put this stuff on, and stop "screwing around".Next time I'll want to try some other packaging other than this little tube I ordered; as I get more of the goop on my fingers than on the little screws; but as regards the product itself, it WORKS.

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.

This stuff is great. It works much better than the blue stuff in my opinion. Leaves a polymer like coating. Easy removal but stays out. It can also be reused unlike the loctite.

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 great
