NOTE Slotted round nuts are usually lathe parts made of stainless steel or non-ferrous steel finding versatile application, in the e
7、lectrical industry for instance. Slotted round nuts can be fixed with wrenches for slotted lock rings as specified in ISO 1703. The main function of slotted round nuts is to fix parts without requiring any specific preload force or resistance to stripping. 2 Normative references The following docume
