18K Yellow Open Top Spring Rings 5mm, 5.5mm & 6mm

Spring rings are the most popular type of clasp used for chains worn around the neck as they are secure and easy to use. 18K Yellow Spring ring clasps are round hollow tubes with a tiny coil spring inside and a jump ring attached for connecting to one end of a chain.  A movable spring tensioned “bolt” has a lever attached. Use your fingernail to push the bolt back to open the spring ring. The bolt is held firmly closed by that same tiny internal spring inside the tubing. It takes 2 hands to open and close a spring ring. These 18K Yellow spring ring clasps have an open top jump ring on top, for easily attaching to one end of the chain.  Often times the jump ring is simply twisted to a closed position when attaching, but that open jump ring is not secure. You cannot use the heat from a torch to solder the jump ring closed as the internal spring will be damaged by the heat. The proper way to close the ring is to laser weld or tack weld the jump ring. These 18K Yellow spring ring clasps are sold by the piece. Choose from 3 sizes: 36C-401  5.0mm 36C-402  5.5mm 36C-403  6.0mm
