GOST 13439-68 is a simple metal fastener that can withstand high impact loads and act as a stopper. The spring stainless washer has the form of a single coil of a flat spring. Failure-free operation of the part is ensured by 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.
