SS Spring Washer
Stainless steel spring washers per DIN 127 Form B are split helical lock washers that create a spring force to maintain bolt tension under vibration. Available in A2 and A4 grades, they provide moderate vibration resistance for bolted joints with property class 5.8 or lower fasteners.

Benefits
#
Spring washers address the need for cost-effective vibration resistance in moderate-duty bolted joints. The split helical form creates a spring force that maintains bolt tension when external loads fluctuate, reducing the rate of self-loosening under vibration. The split ends bite into mating surfaces to generate additional frictional resistance against nut rotation. Compared to prevailing torque nuts, spring washers offer a simpler, lower-cost locking method that can be added to any standard hex nut assembly. Stainless steel A2 and A4 construction provides corrosion resistance in atmospheric, marine, and chemical environments. Spring washers are reusable across multiple installation cycles without significant loss of spring force.
Common Applications
#
