Threadlocker 271, Red High Strength Permanent Thread Lock Glue (0.33Fl oz/10ml) - Lock Tight Screw Glue for Nuts, Bolts & Seal Fasteners, Prevents Loosening, Rust & Corrosion

love this item does the job really good.

This stuff is the real deal! I used this glue to secure bolts on my car's running boards. They carry some weight and are exposed to debris, foot traffic, and car vibrations, but since applying CYAFIXED 271, those bolts are rock solid. No more rattling or loosening! Forget loose bolts and rattling machinery, it locks down threads like a fortress. If you need something to stay put, this threadlocker won't let you down. Highly recommend!

Product Reviewed: Threadlocker 271, Red High Strength Permanent Thread Lock Glue 50ml for $12TL;DR; Nozzle similar to Brand Name; 3/8 bolt & nut test Very strongI use thread locker in a mechanical shop for farm machinery and other repairs.I ran a test on a 3/8” nut and bolt in a vise without any special cleaning. I found the locking action amazingly strong and difficult to get apart. In this case moderate heat should separate such things as the hold was strong enough to make me fear for sheering the bolt.The nozzle on this one is pull off/ push on which opens the internal nozzle similar to brand name thread lockers.5 stars and quite economical.How I review:Reviews start with 5 stars and I subtract points.- 0 for value but I try to provide guidance-0.5 to -3 for product not matching description e.g. stainless steel is actually plated steel-0.5 to -3 for product missing badly on executionI select products carefully so low (1-3 scores) are rare but detailed comments and critiques almost always are in the review. Most of my reviews come out 4-5 range.If possible I dismantle or destroy items to examine inner workings.

I used this instead of the red Loctite 271 thread locker that requires heat to break the bond. When they say permanent, they mean it will be extremely hard to remove by force alone. With Threadlocker 271, I coated the threads and then torqued the bolt according to specifications. The next day, I applied more than twice the tightening torque, and it wouldn't budge. I then used a torch to heat the bolt and was able to remove it, although it still required more torque to loosen than I had used to tighten it. At less than half the price of the name brand, this is a good buy. My Loctite has been sitting in my toolbox for years since I don't use the high-strength version very often, and it still works. We'll see how well Threadlocker 271 lasts, but if you use it frequently, it's a good deal for the money.

The bottle is bigger than I expected it to be, and it does what it is supposed to do. Note that red is considered permanent. I have had to remove bolts that others used permanent thread lock glue on previously. Not fun. When used as intended, this stuff is magical.

I needed to secure some screws which were loose on a piece of furniture I bought and they couldn’t be tightened. This worked well for the intended purpose and I would buy it again.

This product was easy to apply and use once I figured out that the spout has to be pulled upward in order to unlock the bottle.I tested it on a bolt with a 9/16" nut. After setting for 24 hours, the nut was very firmly affixed and could not be removed with a nut driver. However, I was able to break it free using a wrench with a 9-inch handle providing a lot of torque.In short, this product would be fine for many applications requiring a very tight lock, and I intend to use it for such applications. However, the claim on the bottle that the only way to separate the parts is to heat them to 500 degrees is not necessarily true. The parts CAN be unscrewed with mechanical force if it is great enough.

Totally on me, but I ended up ordering the 50ml bottle, and it is massive. Apparently the size I normally get is the 10ml, so this is a lot more than I expected. More isn't always better, since this is labeled as having a 2-year shelf life. No way I'm using all of this in 2 years. Or maybe I'll just use permanent threadlock on everything now?This is not a long term review, so I'm not testing the long term holding power of the threadlock. What I did test was whether it applied the way I expect and holds firm the way I expect after curing. Curing is 24 hours for this. The answer to both questions is yes, it applied well and held on the test, even after just the first 10 minutes for the initial cure.

worked great for my needs
