Review
A spring washer in accordance with GOST 3057-90 is a simple metal fastener that can withstand high impact loads and act as a stopper. The spring washer looks like a single coil of a flat spring. Failure-free operation of the part is ensured due to the fact that the gap of the part diverges in the opposite direction from the direction of rotation of the nut, which prevents it from spontaneously unwinding.
