Product description

Color:Blue | Size Name:0.2 Fl. Oz (Pack of 1)

Product Description

Threadlocker Blue 242 is designed to lock and seal threaded fasteners that require normal disassembly with standard hand tools. Its advanced formula cures when it's confined in the absence of air between close-fitting metal surfaces to prevent the loosening of metal fasteners caused by vibrations. Plus, it protects threads from rust and corrosion to keep them working properly for longer. Threadlocker Blue 242 is particularly suited for applications on less active substrates such as stainless steel and plated surfaces, where disassembly is required for servicing.

From the Manufacturer

Loctite Threadlocker Blue 242 locks threaded metal fasteners against loosening from machine vibration. It prevents leaks and rusting of metal threads for 1/4- to 3/4-Inch (6 mm to 20 mm) nuts and bolts. Metal parts can be removed with hand tools for easy disassembly if necessary. Sets in 20 minutes and cures in 24 hours. Especially useful for small motors, mowers and many types of power equipment.

Same old good product. But, it loses a star for the tube color. YES, that means something to me, in use. The tube for blue threadlocker used to be BLUE. Now, it's red -- same color as the tube for red threadlocker. I can no longer reach into my tub of tubes and easily pull out the one I need. I have to have my reading glasses on, and give it a close look.

I may not be able to hold a relationship together, but thanks to Loctite I can hold my motorcycle together.

Reviewed in the United States on November 29, 2016

Color: BlueSize Name: 0.2 Fl. Oz (Pack of 1)Verified Purchase

I've noticed something. Most manly and enjoyable things tend to vibrate and rattle, especially while making noise. My Harley Davidson caused my vision to blur with images of Americana every time I opened the throttle. While lost in one such reverie, I lost a foot peg because the sound of America had loosened screws and bolts all across my bike.

I experienced this problem repeatedly _until_ I was introduced to this fantastic substance. Just a dab of it along the threads provides the necessary grip to discourage screws from loosening. All of your parts will still be there when you arrive at your destination. This works for everything that has screws and experiences vibration. Bicycle fender? Put some of this on the screws and the bike will rust into a hulk or get stolen before you have to worry about those screws coming out. Lawn blowers. Fans. It's quite versatile.

It's important to stress that this is a worthwhile product. Simply put, it's a watery colored glue. My first thought was "Can't I just use something else?". Sure you can, but it won't work as well. If you use anything stronger than this, that screw may never turn again. The necessary forces can just shear off the head of the screw. Less than ideal. Too thick and it won't follow the threads without applying it with a brush. If it doesn't follow the threads, it will come off and surround the screw head. Loctite Blue is in that 'Goldilocks' zone where it's just right.

Bad Batch?

Reviewed in the United States on April 14, 2017

Color: BlueSize Name: 0.2 Fl. Oz (Pack of 1)Verified Purchase

I feel torn leaving this review, because from all my previous experience with Loctite, it has always been an excellent product, worthy of 5 stars - but the product I received this time had the consistency of water, and was effectively useless; it came out of the tube in a big puddle, dripped everywhere, and refused to stay in the threads. What little did remain in the threads after several attempts did nothing to lock them - I was able to remove the nut with bare hands. And I've seen several other reviews from customers with the same experience, all from this month.

So I'm not sure what rating to give this: the product I received literally deserves a negative star-rating, as it did not work, and I was forced to spend quite some time cleaning up the mess it made. I would have been better off without it. But at the same time, I know that Loctite, in general, is an excellent product, and I don't want to negatively affect its review score too much based on what may simply be a bad batch. I'll leave it at 3 stars for now, as a rough average.

I noticed my .45 Sig Sauer P220 was missing 2 screws, I bought the replacement screws and to make sure they stay put I used this. So far so good 😊 not messy, just squeeze the quantity that you need, cap seals pretty good so product stays fresh. I’m glad I bought this brand.

Blue for Semi-Permanent Installations

Reviewed in the United States on September 2, 2015

Color: BlueSize Name: 0.2 Fl. Oz (Pack of 1)Verified Purchase

If you're buying this you likely know what it is, but in case your not sure, this stuff is used to add some extra grip and fastening power on screws and nuts to keep them tight over time. There are different versions, mainly red and blue. Red forms a more permanent bond. This listing is for the blue loctite and is for scenarios where you may want to loosen or remove the screw or nut you are securing from time to time.

The stuff really works. I use it mainly for making sure my gun sights, mounts, scope mounts, etc., are fastened securely and will not come loose from the vibrations and recoil when shooting. It has been doing an excellent job.

Great stuff, but the tube doesn't seem to be very well thought out.

Reviewed in the United States on July 26, 2020

Color: BlueSize Name: 0.2 Fl. Oz (Pack of 1)Verified Purchase

Obviously from the other reviews you can tell that this stuff is great at doing what it is supposed to do. These new tubes are horrible though. There used to be a 'poker' in the caps that would barely open the tube and let you use whatever you wanted. That is not present on the tube I received. No problem, I'll just poke a hole. Well, no. Apparently the cavity doesn't extend out to anywhere near the end of the tip so thumbtack and push pin just wouldn't penetrate. Switching to a knife, after 4 or 5 small cuts to remove the end material it pretty much exploded on me and I lost a quarter of the bottle. Should have thought it over more or been more patient but I wanted to get my project done and didn't anticipate having to futz with the Loctite.

In the future I'll probably just take a pin and poke a hole in the side of the tube down from the tip. That may end up letting out more than I want but will save the hassle.

TL;DR - The cap doesn't have a self opening function. Be patient in opening with tack or knife or it will explode on you.

Did not work for my application. Where is the old loctite that worked like glue?

Reviewed in the United States on October 29, 2019

Color: BlueSize Name: 0.2 Fl. Oz (Pack of 1)Verified Purchase

I found this product worthless for my application. Many years ago I used loctite to hold the screws tight when my sons and I would race RC cars. I could put it on the nuts and bolts and secure them from the brutal environment of RC car racing. It worked like glue but was easy to remove when I had to do maintenance after crashes. That product seems to be no longer made. This product which claims to do the same thing, requires that is be spread on the threads of a screw and then screwed into a threaded object. It works by the lack of air on the threads. It does not cure in air and leaves a mess if too much loctite is used. For my application the nut would not have enough surface area to provide a good bond. So I just threw to product away. Maybe it may work for some applications but it did not work for mine. I would love to find that old loctite; it worked great no matter what the size of the screw and nut that was used.

Almost lowered a star for being so good.

Plain and simple this product is amazing. This blue version should be removable but I'm having a hard time doing so. I just need to readjust the position of something I glued in place. Anyway that would be my own fault if I cant remove it. I use the product that I glued daily. My product hits the road every day with bumps of the road but I am very confident with Loctite that it'll stay in its place, and it has now for over 2 months. I cant recommend this product enough. Just be sure that what you are gluing is exactly where u want it.

Great product prevents loose fasteners but allows later adjustments.

I have used this for years as an industrial mechanic. Now retired, I find it useful around the house and for mechanical devices at home and at the cottage. It prevents fasteners from loosening by themselves, but allows them to be later unscrewed when you need to make changes. - as opposed to the "Red Loctite", which is a permanent fused thread locker.

Good stuff

Reviewed in Canada on December 14, 2017

Color: BlueSize Name: 0.2 Fl. Oz (Pack of 1)Verified Purchase

Use this stuff mainly on my car and electronics. So far it's worked amazingly. I would say that it is a little overkill for electronics but it's perfect for use on my car. I've used it on a few nuts and bolts holding together my exhaust system and so far they have not failed or come undone. At the price point, it's also good value considering how much threadlocker is actually inside the small tube. All in all, must buy if you need it.
