Rectangular Section Spring Washers in Bright Zinc Plated (BZP) Steel

Spring washer designed to help prevent loosening of bolted joints under vibration. Also know as a Split Lock Washer and a Split Ring Washer. This type has a rectangular section and is manufactured to ASME B18.21.1-1999. Where even distribution of load on the mating surface is the primary requirement an alternative spring washer or a flat washer would be a more suitable solution. In addition Spring Washers do not offer protection for the material being fastened.
