One of the Best ThreadLocker Ever
Jus today Received the Product on 20May Monday Around 3:30 pm, Jus Loved the Packaging completely Wrapped with Bubble Wrapping and Kept in the Perfect sized Box and Sended Me, Jus Curious about the Quantity as it’s a 50ML Bottle, but when I opened the Bottle Cap I Saw the Bottle was Half Empty, AS ITS 50ML WRITTEN on the Bottle, MAYBE IT COMES THE SAME WAY Which Is Half Bottle or Maybe It’s Tampered before the Packaging at the Shop it self Maybe Emptied the Bottle in Half and Only HALF QUANTITY WAS SENDED TO ME, The MRP IS something Around 1449/- written on the Bottle, On Amazon it’s Written 1099/- and then After Discount on Amazon u get it for 549/- but due to the half price the bottle is empty or I don’t know what’s wrong but the Quality is Amazing, the smell of the Adhesive is Fresh n Neat, which makes it more stronger when applied to a certain threadLocker or a Bolt, even the Packaging from the shop till my home was amazingly perfect n clean but m only concerned with the QUANTITY I Got after paying 549/- if I get a Half Bottle it’s Pathetic Then, Extremely sorry to say this but yes this is the Fact that Happend with me Today, Rest Everything is Cool n Good, U ALL PEOPLES CAN BUY THE PRODUCT BUT JUS MAKE SURE ABOUT THE QUANTITY YOU RECIVE WITH IT IS UP TO THE MARK OR NO… THANKYOU, HAVE A GREAT DAY❤️🙏🏻

Loctite is no f* joke!
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.

Threadlocker at its best.
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).

Get the smaller one
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.
