A barrel screw clasp is a popular jewelry fastener shaped like a small barrel or cylinder. It consists of two interlocking halves that screw together, forming a secure closure. These clasps are often used for necklaces, bracelets, and anklets because they combine reliability with a discreet, streamlined look.

How It Works
Each half of the clasp is threaded on the inside. To close, you align the two halves and twist them together until they’re tightly secured, much like screwing a cap onto a bottle. To open, simply twist in the opposite direction. This screw-action mechanism ensures that the clasp won’t come undone accidentally, making it especially useful for everyday wear.
