Nuts Nuts according to GOST 9064-75, etc.

When using threaded fasteners, where the nut is its element, a number of conditions must be observed for the proper use of nuts. Nuts with large threads are used where static or insignificant variable loads act on the elements of the fastened structures. Nuts with large threads are used, for example, when assembling frames of industrial installations, supports of high-voltage power lines, when assembling various pavilions. When the devices are operating under vibration conditions, significant alternating loads, as well as with significant temperature differences, the small thread of the fastener works better compared to the large one. Therefore, in such cases, nuts with fine threads are used. They resist self-unscrewing more reliably. They are used in engines and other mechanisms that create vibration and shocks during operation.
