RS PRO Spring Washers A2 Stainless Steel - Metric


From the trusted RS PRO brand, these spring washers are ideal for fastening applications where vibration is a concern. These washers are constructed from A2 stainless steel, which assures an excellent resistance to wear and tear. To avoid the loosening of bolts and fasteners over time, spring washers are ideal.

Features and Benefits


• Durable and high-quality spring washers

• A2 stainless steel construction, type 304

Applications


Spring washers are designed to be fitted between a bolt, nut or other washer and the surface panel. Their unique construction allows them to absorb vibration from the bearing surface that might loosen fasteners over time. As such, they are ideal for use in machinery where high-levels of vibration are prevalent, from industrial machinery to domestic appliances such as washing machines.
