Abstract

Specifies requirements for gauges for single start parallel general purpose metric screw threads manufactured to either AS 1721 or AS 1275. It covers types of gauges, inspection of screw threads, design features of screw gauges, material and hardness requirements, and limits and tolerances of gauging elements, and is technically identical with ISO 1502, ISO General Purpose Metric Screw Threads - Gauging. Appendices give notes on the function, use and checking of gauges, the bases for the gauge deviations and tolerances, and detailed examples of deriving specific gauge limits.

Scope

This standard specifies requirements for gauges for single start parallel general purpose metric screw threads.
The standard covers types of gauges, inspection of screw threads, design features of screw gauges, material and hardness requirements, and limits and tolerances of gauging elements.
The standard also gives information on symbols for screw threads and screw thread gauge parameters. Appendices are included giving notes on the function, use and checking of gauges (Appendix A), the bases for the gauge deviations and tolerances (Appendix B), and detailed examples of deriving specific gauge limits (Appendix C).
