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

I dont need a screw or nut coming loose on a $500 hobby grade helo or Drone, so I use this to lock it down, seems to work just fine for my application.

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.

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.

Does what it’s intended to do. I work as a technician and i prefer Loctite brand over Permatex due to the gel type consistency. It holds up in the bottle better over time in my opinion.

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

Did the job!

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

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!

This stuff is comically strong. Don’t put it on anything you ever want to remove again.
