Green 680

Works great. No complaints. Price was much better than certain other brands. And quality and function is exactly the same.

Bought this for a watch repair and ended up using it on my wife’s purse too. So far, every screw has stayed exactly where it’s supposed to. Strong enough to stop things from loosening, but still removable when needed. Basically couples therapy for nuts and bolts.

Great thread locker and excellent price! I prefer this to Loctite brand because this has remained a gel consistency and is easy to apply. The name brand is usually like water and runs out the bottle too fast and doesn't stay put on a bolt.

Performs as advertised. What I like most is the bottling, it is excellent for the use of this product.

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.

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.

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.
