DIN 137 B curved spring washers are single-wave spring washers designed to provide elastic compensation in bolted connections. They effectively absorb shocks and vibrations, preventing loosening of fasteners. Compared with DIN 137 A, Type B washers have a larger curvature, suitable for applications requiring greater elastic deflection.
