What Stands Out
High Temperature Resistance
LOCTITE 242 withstands extreme temperatures, ensuring secure bonds on automotive components even in challenging conditions, making it a reliable choice for high-performance applications.
Medium-Strength Formula
Designed for removable applications, this medium-strength threadlocker allows for easy disassembly, catering to both professional mechanics and DIY enthusiasts who require versatile fastening solutions.
Anaerobic Technology
This advanced anaerobic formula cures in the absence of air, providing reliability and durability for metal parts, enhancing performance over traditional products, and reducing the risk of loosening under vibration.

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.
