Crystal rivets connect your metal pieces together and will add a splash of color and elegance to your designs. These rivets snap into each other making riveting a cinch. They fit in a 5/32" diameter hole, which can be made with the ImpressArt large hole punch. To close the rivets, simply snap the crystal head into the end piece, place on a rubber block, and hammer the end piece until the connection is tight and secure. Includes 5 crystal rivets per pack.
