ISO 1502:1996 is an International Standard that provides detailed information on the manufacturing and use of gauges for checking ISO general-purpose metric screw threads. It specifies the recommended features of gauges for both external and internal threads, and provides methods to distinguish between threads that comply with size limits and those that do not. The standard's purpose is to ensure interchangeability of screw threads and to help prevent disputes between manufacturers and purchasers.
