Vibra-Tite VC-3 Threadmate, Removable, Thread locking,Sealing 30cc Bottle 21330 supplier:suncoastprecisiontoolsoutlet

This is the best product for keeping scope ring screws or any bolt or screw from backing out from vibration. the only draw back I found is if the bottle is left on the shelf for any length of time it tends to go bad once the cap has been open even if you seal the cap tight .So once you open it use it up or it might not be good the next time you got to use it.

Good product, terrible bottle. The lid crumbles upon loosening due to locking compound on threads. The applicator is also quite large and imprecise. I transfer it to a cheap nail polish bottle, much less issues.

Once you open the bottle, better use it all, gets hard in the bottle

I use this almost exclusively especially on small fastners in things like firearms. Think of it as an in between thread locker red and blue. More hold than blue but you can still break the fastner loose without heat. That said buy the small tube unless you are doing 100's of fastener a day. The larger glass container will break long before you use it all. Also the brush makes it difficult to apply precisely which also leads to the above issue. The VC-3 you will eventually get it on the threads of the cap to the glass container locking it to the container and its almost guaranteed you crack the cap getting it off. This means its no longer air tight and when you go to use it next time everything in the container has set.
