Loctite Threadlocker 221 Purple Jewelry Adhesive

Loctite® Threadlocker Purple is designed to lock threaded fasteners closed to protect against them vibrating loose. Since the threadlocker creates a tight seal between the threaded fastener and the item, it also prevents leaks and the threads from rusting. The threaded parts can always be disassembled with your typical hand tools, ensuring that you will be able to continue to use the items you want threadlocked. It is a low strength threadlocker that is ideal for fasteners 1/4" (6 mm) or smaller.
