B1.22M - Gages and Gaging for MJ Series Metric ScrewThreads

This standard is being maintained under Stabilized Maintenance. Stabilized maintenance is an option for maintenance of a standard that requires status review every 10 years rather than revision or reaffirmation every 5 years. The Standards Committee shall consider all requests and recommendations for change to standards maintained under the stabilized maintenance option from any materially affected and interested party. The request shall be made in writing and should include the rationale for the particular request in order to facilitate review by the Committee.

This Standard provides essential specifications and dimensions for the gages used on MJ series metric screw threads, and covers the specifications and dimensions for the thread gages and measuring equipment listed in Tables 1 and 2. The basic purpose and use of each gage are also described. For easy reference, customary conversion of metric tables has been incorporated in Appendix D. The Appendices contain useful information that is supplementary to the sections of this Standard.
