Loctite 277 442-21434 10ml High Strength Threadlocker, Red Color

Works well. Just wish that it was available in a small quantity. Just needed it for one special, large, bolt.

Product worked as intended. Would buy again, good price. Thanks

Works good on large fasteners

This would get a 5 star if they made a better bottle, first bottle i thought it was my fault for leading it upside down but somehow this thing still leaks i think its pressure related/with the tip but once you turn it upside down and squeeze some onto your threads if you put the cap back on and sit it properly upwards youd think gravity makes the fluid go back down into the bottle but for some reason it keeps pouring upwards and ends up leaking through the cap no matter how hard you tighten it I needed this specific strength and im not cheap so i ordered it again regardless most bottles are one use for me anyways but if you plan on keeping this for a long time i wouldnt bother the bottle/pour design is junk

Purchased this for various projects around the garage. Something that should be in ever toolbox is red and blue loctite.

The item pictured is what I received. It’s .34 and not .8 ounces as stated in the description. This product only works in the lack of oxygen. It’s not like super glue and will stay wet when exposed to oxygen. Basically it’s apply to the threads, lock down tight, and forget. The bottle won’t leak if you just snip off the nib. The .2 ounce tubes work the same. Just needs a small hole to press the liquid through. Especially helpful for scope base mount screws! I always keep some on hand.

Note to buyers: if you buy this stuff. Test before you trust it to hold anything critical. I have used this product at work, and it is typically great stuff and holds solid. But either I got a counterfeit product or it is seriously past its expiration date (the use by date on the bottle states Jan 2019). The liquid was more like a gel. It was very very viscous and difficult to get out of the bottle. Also it doesnt ever seem to fully cure. I tested some since I was uncertain about it because of the high viscosity. I put two nuts on a piece of threaded rod, and tightened them together. Both had loctite applied. After 3 days at room temperature to cure, I tried to remove the nuts. After breaking them loose with a pair of cresent wrenches, I was able to spin the nuts off by hand. There was some resistance, about the same as typical for dirty/greasy threads. but for high strength thread locker, I should think I should not be able to spin them by hand, and with no heat applied either. Also, after a I removed the nuts, I checked the residual threadlocker on the thread rod. It was still semi-liquid. even after 3 days it wasnt cured. I repeated my test and let it sit for a full week (7 days). exactly the same results.

What I needed and saved running around looking at auto parts stores who may or may not have had it!
