Bought this to put on some bolts i installed on my Honda Rodgeline to add extra tie down strap points. I also use this stuff when I don’t have a nylon nut for a project I am doing. Helps secure the bolt better but can hand tool it back out when needed. Good value and works great

I can confidently say that this product is an excellent choice for anyone in need of a reliable and easy-to-use threadlocker solution.One of the things I love about this product is its medium strength. It provides just the right amount of locking strength for a wide range of applications, from automotive repairs to household projects. It's not too weak that it will come loose, but also not too strong that it will be difficult to disassemble in the future.The blue color of the threadlocker makes it easy to see where it has been applied, which is especially helpful for ensuring that all areas have been covered. I also appreciate the fact that it comes in a 6 ml bottle, which is a convenient size for both small and large projects.The application process of this threadlocker is very straightforward. Simply apply a small amount to the threads and let it dry. The threadlocker dries quickly, and I have never had any issues with it dripping or running.One of the things I appreciate the most about this product is its reliability. Once it is applied, I know that my threads will stay securely locked in place, even under high levels of stress or vibration. This provides me with peace of mind knowing that my repairs or projects will be sturdy and long-lasting.Overall, I would highly recommend this threadlock to anyone in need of a reliable and easy-to-use threadlocker solution. It provides just the right amount of locking strength, is easy to apply, and dries quickly. It's a must-have in any toolkit.

赤いロックタイトも持ってましたが、よく既製品に青い色のネジ止め剤が塗られていたのでこちらを購入してみました。強度はよくわかりませんが、塗り色は意外と薄い青色でした。
