Spring bars are used to connect your watch band to your watch or connect a watch buckle or clasp to your watch band. The ends of the pins are double flanged and have a spring at the end of the bar that allows for easy removal and installation. Our spring bar pins are made in stainless steel. Most watches use 1.5 mm thickness. Sizes available from 6 to 28 mm. Manufactured by NE Watchbands exclusively for North East Watch Bands.
