243 Blue 50ml | Medium-strength Threadlocker (M6-M20) | Prevention of loosening | Secure bonding for machinery, engine & vehicles | Thixotropic | High temperature performance | Oil tolerance

Very good product it prevent bolt loosening must use in vehicle some bike bolt become loose over the time and just use 1 slim verticle line on threads straight it is enough amazing product

This is 50ml bottle and has a expiry of 18 months and will the effectiveness reduce after that? I don't know but a chemical like this how can there be an expiry. Get the 6ml tube if you don't have use for the full bottle of it. All it takes is a drop or two even for longer screws. The product itself works and keeps the nuts and bolts together pretty well.

My recent purchase of this is very good. Most of the users need to know that this product ships with a 100ml bottle and users feel they are cheated but due to the propertied of the liquid it is shipped in 100 ml specially made plastic bottle which is breathable type and hence solution will not solidify. When you use it within threads due to lack of air, solution will start working and will form a weld like hard. Really happy with the trader as the shelf life was well over 10 months. I hardly rate any product 5 and this and the seller definitely deserve it. Keep it up. Finally thanks to Amazon team for onboarding such good seller and bringing good products to customers. Hip hip hurray !

Good product. Works great and does what it says.

Edit: Shake well before every use. Bought the product to fix loose screws and nuts of utensils. It seals those nuts which gets loosened automatically after consecutive tightenings. Apply a drop in the nut and screw it properly using proper screwdriver/hex tool. The screw/nut does not get loosened by itself. make sure the screw/nut to be proper clean (no oil no grease no rust). The price is on the higher side but the product is too good. One will get local product for 40-60 Rs that works (so so quality).

Product arrived at 7pm. Instead of morning.

Screws are tight af! Infact, screws are so tight that I am unable unscrew it now! One item I locked with Loctite, I had locked with the intention to never unscrew it again, but the universe had other plans and an inner component broke, so to have it replaced I need to open it, right? *sigh* so now for the life of me, this thing won't unscrew! Probably will need to use heat therapy to weaken the bond. On the bright side, this item is legit and just a teeeny-tiny drop is enough to lock screws that can open with applying say, grizzly strength, or a few drops are enough if you never ever want it to unscrew unless you use some nuclear powered industrial strength tools.

Okay but I am looking a hard and better.
