LOCTITE 242 Threadlocker for Automotive: High-Temp, Medium-Strength, Anaerobic | Blue, 6mL Tube (PN: 37418 - 487229)

Affordable, and happy it came in a small size as I didn't need a lot. Seems to hold well, easy to use, and with the cap you can seal it right back up and use it for later. Will be buying more. Hope this helps!

I started using Loctite products over 45 years ago and I learned how well it performed while assembling aluminum parts for instrumentation. I now use it on my guns as I assemble them to prevent parts from coming loose from shock and vibration. I just put together a new AR15 build and I used it all over the gun for the accessory parts. I installed a new Magpul MIAD pistol grip, a Magpul vertical rail grip, a tactical flashlight, a Magpul front and rear MBUS set of sights, a Vortex 3X flip up scope and a Daniels Defense Omega Free floating hand guard quad rail. All of the screws and Allen head screws had Loctite applied as I did the assembly. I even applied it to the mounting screws on the Aimpoint Pro red dot sight. I like the blue Loctite as it helps to hold the screws more securely in place and helps to prevent corrosion which is important on a rifle or gun. The blue formulation locks the parts in place but you can still take the gun apart when you need to. I recommend that you not use the red Loctite on gun assembly and it is very difficult to take apart as it has a much stronger holding power. This is a great product with a proven history of working in difficult applications. I rated it at 5 stars and I recommend it to you.

Don't want screws to come out or nuts to fall off? Get Loctite. I've ben using this stuff for years, most recently to stop a screw in a office chair from falling out. Loctite holds things securely, but can be deliberately "broken" with a sharp twist of a screwdriver or wrench. I'd call this a "medium duty" thread locker -- great for chairs, eyeglasses, gun parts, and just about anything threaded not subject to intense vibration. For example, I would use Loctite Blue on interior parts of a car, but not on screws related to the drivetrain. I find Loctite Blue to work well with metal and strong, stiff plastics. It does not make a good bond with porous materials like wood, sheetrock or concrete, or on very bendable plastics. It handles weather quite well, so you can use it for outdoor applications. I have never had a piece secured by Loctite Blue come apart accidentally, and I've also never had problems "breaking" the Loctite to get the screw, nut or bolt out. By the way, there is an industrial strength version, Loctite Red. However, it is extremely difficult to remove Loctite Red, so only use it in situations where you don't plan to ever remove the screw, nut or bolt.

Worked great on my mini bike muffler that was loosening off the straight pipe.

While the description says "red", this product is Loctite 242, which is the blue threadlocker. Learn from my mistake, and go by the Loctite number, not by the title. If you need blue loctite, this is all good. If you wanted red loctite, you are in for a disappointment.

Does what it says. Lock tight brand. What do you expect. Shipping was fast and reliable.

Standard blue loctite. Does what it's supposed to do.

ok

I needed this because the screws on my computer had a nasty habit of getting loose and falling out. So far it has been incredibly useful in many other loose-screw related situation around the house, so I'd totally recommend this.

Hay aplicaciones que requieren, o al menos es muy recomendable, utilizar un fijador de rosca. Para eso está toda la línea de estos productos Loctite que resaltan por su calidad. Este producto lo utilizo al ensamblar piezas en mi moto, y va a ser igual de útil en el carro. Esto es dónde la vibración puede hacer que se afloje algo.

Efectivo

Anything with the Loctite brand is going to be of quality. The threadlock works fine on steel and titanium bits and creates a strong bond to the pieces.

I own a Benchmade 52 'Morpho' Balisong and a Benchmade 'Contego' Axis-lock, and coincidentally, they both needed Loctite 'Threadlocker' 242 to keep the pivot screw from loosening. The Balisong needed threadlocker on every screw, which I only realized when one of the tiny zen-pin screws went flying amidst the flipping. If you own knives, this is the stuff you want. If you have no idea what the f*** I'm babbling about, this still might be the stuff you're looking for. It locks screws up solid, but not so solid you can't break the grip with a driver. It won't mess things up irrevocably if you apply it then realize you forgot a washer, for example. But as far as hard use, preventing screws from loosening due to vibration and shock, it's excellent.
