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

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

You have to watch were you use this very strong.

This works exactly like and exactly as well as the 10x expensive Loctite brand. I'm VERY pleased. I fixed a high load idler shaft on a commercial mower with it, gluing in the two bearings, in a bore they could be slid in and out of by hand. There was NO mechanical locking method. The arm has now withstood many hours of mowing with no movement of the bearings in their sleeve.

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
