Review: Works good! - 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!
Review: A great product with a history of working well in difficult applications! - 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.

## Questions & Answers

**Q: Can i use this on metal set screws going into a plastic housing??**
A: No, this is for metal-to-metal applications. Loctite 425 is recommended for plastic-to-plastic and plastic-to-metal applications.

**Q: Is this product ideal for locking my camera strap screw in place?**
A: Yes, I'm using blue Loctite for a BlackRapid strap in a DSLR tripod screw hole. I've also used it for securing Arca-Swiss tripod plates to camera bodies.

**Q: Is this good for Conceal Carry holster screws?**
A: To tell you the truth, I don't have any issues with my Conceal Carry holster screws coming loose. But if I did, Loctite 242 is the first place I would go because the idea of losing all of the screws in my Conceal Carry holster is unconscionable.

**Q: Does it interfere when using a torque wench?**
A: I always heat up the hardware with a heat gun. This softens the bonding, reducing strain of removals.

### ⭐⭐⭐⭐⭐ The perfect thread locker to stop screws, nuts and bolts from coming off accidentally
*by A***Z on April 13, 2015*

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.
