These split spring washers are ideal for fastening applications where vibration is a major concern. These washers are constructed from stainless steel, which assures an excellent resistance to wear and tear, and makes it suitable even for use in marine-grade environments. The spiral design provides a spring force under the mating parts which ensure they are always in tension and don't come loose.
