Purple 222

Great product that is indistinguishable from the brand name stuff. You get a huge quantity by comparison for a much better price. Used it for screws on red dot optic mounts and nothing has worked loose after being used in service.

Bought the 222 purple for use on a knife I use frequently with a screw that kept backing itself out. So far it's worked perfectly. The thread locker is pretty thick so it's easy to apply even to tiny screws like in a knife. Zero complaints, great value compared to the other name brand.

work great fast dryine time and very easy to use

Service technician by trade and this is best thread locker I have ever used! I love the bottle dispenser lock! Makes use so easy. As for the price, you can’t beat it! FABULOUS PRODUCT.

This thread locker seems to work, however I found it a little tricky and did not see any info on how to actually open the bottle ... first there's the main cap, ok just pop that off it is tight at first but simple enough right? well yes and no, as with most you have to pierce the nozzle to get the liquid to flow so I did that and it still was not dispensing any liquid. NOTE: Just in case others are unsure and have the same issue I did then the following info is for you. Then I noticed there's a spot that sticks out lower on the nozzle this is a secondary seal that you must pull up on to unlock it (See Pic), while this is great it would be nice if the info to open the bottle was included in the package. So unless I somehow missed it I did not see any ... Anyway with all that sorted the product works as it should and seems to hold tight and sets quickly, but because of the lack of proper instructions I am docking a star. O and yes as others have mentioned the bottle is half full. I checked the weight of the product and it is around 50g minus the weight of the bottle, so you are getting what they say your getting, its just in a large one size fits all bottle that they must use for all there products which in my opin is just ridiculous and one of the reasons for many bad reviews, they should really just use a smaller bottle for a smaller amount, but because you only use a drop or 2 at a time this amount is still quite a lot, and should still last a very long time. Yes I can recommend this product, as it does seem like a decent value, just know it will come in an oversize bottle, but they are not shorting you on the actual product.

I always have a bottle of 243 and 680 on hand and use them all the time on all sorts of stuff that needs attention. Yes, the bottle is supposed to be "half full" , the air space is to prevent it from hardening in the bottle. It is sold by weight, not volume and hardens in the absence of oxygen. The application nozzle is opened by pulling up on the white ring at the base, and useful for preventing accidental spills. Not much fun finding the tipped over bottle somewhere with half the liquid hardened underneath it IFYKYK.... Slightly more viscous than the name brand which I think is nice, so I get a better chance of installing the fastener in difficult locations without it dripping off. Works the same, looks the same, smells the same, and hardens the same, at a fraction of the cost.

Good stuff mix it with a little titebond wood glue for driving screws, bolts, etc, works really good

Accept no substitutes! This stuff works. Use it on my auto repairs and have never had a bolt vibrate loose
