How to End a Barrel Clasp

Updated March 23, 2017

Clasps are connectors attached to the ends of jewellery which allow for easy removal and sizing. They come in a variety of styles and shapes to suit different applications. Some examples of clasp categories includes the box, hook-and-eye, toggle, lobster claw and barrel. Barrel clasps are cylindrical in shape and named for their visual similarity to barrels. There are two types of barrel clasps: screw-in and magnetic. Screw-in clasps feature a male and female pairing similar to a nut and bolt. Magnetic barrels have metal ends that rely on magnetism to hold the jewellery together.

Fold a piece of tape over the string at one end of your necklace or bracelet to hold the beads in place while you work.

Straighten the attachment loop on both ends of the barrel clasp with pliers.

Push the wire down into the barrel clasp. Remove it from the other end. Save for a future project.

Insert the loose end of string into the hole left by the wire so the open end of the clasp faces away from the strand.

Double-knot the string.

Slide the barrel up to encase the knot.

Apply a drop of jeweller's epoxy to the knot using a toothpick.

Remove the tape from the string and repeat the process.

Open a jump ring to form a "C."

Hook the jump ring over the end of the chain and the barrel clasp loop.

Close the ring. Flatten the ring with nylon-coated pliers, if necessary.


When working with beaded necklaces, be sure to adjust the beads to prevent gaps caused by poor knot positioning. Add additional jump rings to enlarge the piece for a custom fit.
