Loctite Thread Lock Editorial Review

The Loctite 487229 Threadlocker 242 is a blue medium-strength threadlocker that is suitable for metal-to-metal locking applications. Customers have used it on a variety of items, including camera straps, tripod plates, Conceal Carry holster screws, and scope mounting brackets on rifles, with great success. It should not be used on plastic-to-metal or plastic-to-plastic applications, and it should not be used for anti seize purposes. The product is easy to install and comes in a convenient size for smaller tasks. The only warning is that it can leave a blue mark if too much is used, and it will drip if not applied carefully. Overall, customers have found the Loctite 487229 Threadlocker 242 to be a great and dependable product that works as intended and helps them get their jobs done.
