This International Standard specifies the form and dimensions of ends of parts with external ISO metric screw thread (e.g. bolt, screw and stud ends) recommended for use. They apply to standardized or nonstandardized threaded parts.
For each end type, a symbol is specified and it is intended that these symbols be used when specifying one of the ends for threaded fasteners.
