Loctite 243 threadlocker is a medium-strength, removable adhesive specifically formulated for locking and sealing threaded fasteners that require disassembly with standard tools. This 6ml version is perfect for maintenance professionals, manufacturers, and DIYers needing precise application in limited quantities.

This threadlocker is ideal for applications where fasteners might need future maintenance or adjustment. It’s commonly used in:
Automotive maintenance (e.g., valve covers, water pumps)
Industrial machinery
