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

Stopped ebike pedal crank arm from coming loose

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

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

Great product... although my purchase was tainted by the photo of the bottle that is currently being used on the product page... the bottle in the photo says 50ml/1.69 oz. BEWARE, the bottle that you are purchasing is 10ml/.34 oz.. Makes the purchase confusing. It would be nice if the seller would change the photo to reflect the actual product!

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.

Good for us on aluminum rivnut inserts

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

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