Vibra-TITE11110 111 Low Strength Removable Anaerobic Threadlocker, 10ml Bottle, Purple

Better than regular threadlock, especially for a rifle scope, arrow broadhead/field points, and bow accessories.

Many small / delicate screws. Often other parts, hard to get to.Helps keep your sanity, knowing things don't vibrate loose.Not permanent, works as promised.

Really good thread locker

I bought this to be used on pocket knives. I already used it on several knives and doing a good job. It’s a lil bit messy to use on such small screws but I am used to it. I would suggest using the gel version or loctite blue stick if using it for very tiny screws as they are less messy. Again, poor packaging, the bottle was crushed during shipping as there was no protection for the bottle. The bottle is sturdy enough that no spill was seen but the white cap was off and plastic clear tip was bent - 1 star off.

First time I've used a thread locker. This was really easy to use. I was skeptical but it actually works. Very helpful. This isn't the permanent thread locker (obviously), it's cool that they make it in different strengths.

Works just like Loctite purple, at half the cost (or less). I used it to install a scope on a rifle, and later realized I hadn't left enough room for the recoil (just can't forget Newton's 3rd law). So I got a bandage for my eyebrow, and hoped I'd be able to remove the screws -- it was a snap. They were tight, but came loose with only slightly greater torque than without a thread-locker.Best of all, after reinstalling the scope (again with this stuff), I've put over 250 rounds through the rifle, and the scope is still tight as a tick.

A must for gun smithing.

I tried this out for locking the pivot screws on folding knives. Those are pretty small screws ( <1/4" ) so this would seem to be the appropriate product. But I found myself having to use a large amount in order to keep them from loosening up, far more than is practical. There is some shock and vibration but very little actual force acting on a pivot screw.To be honest I am kind of disappointed with Vibra-TITE products. I tried the VC-3 first and it also would not hold. Other people seem to have good luck with the stuff but for me it wasn't worth the trouble waiting for it to dry, the mess, etc. I decided to give them another shot with this low strength threadlocker, but in the end I'm just going back to my Harbor Freight blue threadlocker. It's cheap and it works.
