I purchased this Loctite primarily to secure the optic on my home defense firearm, and it has performed flawlessly. After multiple range sessions and hundreds of rounds fired, my optic hasn't shown even the slightest bit of movement - exactly what I needed for a critical application where reliability is paramount.The product proved so effective that I started using it for household repairs too. Those annoying, constantly-loosening ceiling fan screws that created a shaky noise? Completely silenced after application. The medium-strength formula seems perfect - strong enough to keep things secure, but still allows for disassembly when needed with standard tools.Application was simple with the precise nozzle, and a little goes a long way. I appreciate that it dries clear and doesn't leave messy residue. For anyone needing to secure screws in firearms, machinery, or household items, this Loctite delivers professional-grade results.For those using it for firearm related screws: Always follow manufacturer instructions for firearm applications and allow proper cure time before use.

The Loctite Threadlocker Blue 242 performed effectively, securing the threaded components as promised. However, I found its consistency to be quite thin, which caused it to drip excessively while I was applying it. This watery texture made it a bit challenging to manage, resulting in some unwanted spillage that required extra cleanup afterward. Overall, while the product delivered on its intended purpose, the messiness during application was a drawback.

Dries Quickly. Seals well. Sticks the bolts down. Easy to use and doesn't make a mess. Heat Resistant.

Worked well to secure screws on scope rings. Quick arrival and good value on Amazon.

Just need a few drops to keep bolts from loosening. Resolved a few ongoing headaches with bicycle parts that would loosen after every ride and avoided potentially costly repairs.
