An allen screw was loose on the handle of my kitchen faucet. Tightening with a few turns of the allen key was sufficient to keep it secure for about a day or two. I pulled the handle off, thoroughly cleaned all of the threads and applied a drop of Loctite 242 to both the male and female surfaces. It has been a week since I repaired the threads in this way and there is no hint of the allen screw from loosening.

Pros: High Strength: Provides a strong bond for heavy-duty applications. Permanent Adhesive: Ideal for critical fasteners that will not need to be disassembled. Excellent Resistance: Withstands high temperatures and various chemicals. Versatile Use: Suitable for both automotive and industrial applications. Cons: Permanent Nature: Difficult to remove once cured, which may not be ideal for all users. Curing Time: Requires some time to fully cure, which may delay projects. Price Point: Slightly higher than other threadlockers on the market. Detailed Review: Performance: Loctite Threadlocker Red 271 excels in holding heavy-duty fasteners securely in place. Once applied, the bond strength is impressively robust, ensuring that nuts, bolts, and fasteners remain locked under stress and vibration. Ease of Use: The product is straightforward to apply. A small dot is sufficient for most applications, and the precision nozzle helps prevent over-application. The drying time is acceptable, but users should plan for a full curing time of up to 24 hours to achieve maximum strength. Features: Temperature Resistance: Can withstand temperatures from -65°F to 300°F (-54°C to 148°C). Chemical Resistance: Resistant to gasoline, oil, and various solvents. Application Versatility: Suitable for metal surfaces, which makes it versatile for use in various industries. Quality: Loctite is a well-known brand in the adhesive industry, and Threadlocker Red 271 lives up to its reputation. The consistency and strength of the adhesive ensure that it performs reliably in demanding applications. Value for Money: While it may be priced higher than other alternatives, the strength and longevity of the bond can save money in the long run by reducing the need for maintenance and reapplication. For critical applications, the investment is often worth it. Experience Using the Product: Personally, I have used Loctite Threadlocker Red 271 for securing bolts on automotive parts and for machinery that undergoes frequent vibrations. The results have been consistently reliable, with no loosening or need for re-tightening after applying it. The peace of mind that comes with knowing fasteners are secure is invaluable. Recommendation: For anyone dealing with high-stress applications or where permanent fastening is required, I highly recommend Loctite Threadlocker Red 271. It provides exceptional bond strength and reliability, making it a go-to for professionals and DIY enthusiasts alike. Conclusion: In conclusion, Loctite Threadlocker Red 271 stands out as a top-tier product in the realm of threadlockers. Its performance, quality, and ease of use make it a valuable tool in anyone's arsenal. While its permanent nature may not be suitable for every user, for those seeking a high-strength solution for nuts, bolts, and fasteners, this product delivers on its promises.

I've been using Loctite's "blue" threadlocker on just about every nut and bolt that I don't want to come loose on it's own for many years and it's faithfully held them tight, but is still removable with basic tools. I've tried several brands and Loctite has just been the most consistent whether it's indoor bolts holding things together or for automotive use where high temperature and humidity fluctuations seem to negatively effect competitors products.

Easy to use. Exactly what it shows on the box. The glue is strong and works as advertised.

Must have product for small screws and moving parts that you dont want to lose. Especially useful with firearms for installing sights and other items that need the small screws and what not retained. It is extremely useful and definitely worth the price. It is easy to apply with the dripper style tube. Does not take much especially of the red so this tube should last quite a bit for most people as I bought a tube years ago, use it quite often and still have some left that will last me a long while
