Type:

This standard covers the gaging practice and gage requirements for aerospace metric screw thread, MJ profile in accordance with MA1370.

Purpose:

To establish the gaging system in accordance with ANSI/ASME B1.3M for final assessment of dimensional acceptability of the product complete thread (excluding the incomplete lead or runout thread).

Application:

The gaging practice established in this standard applies to the referee inspection of MJ screw threads, and it is not the intent of this standard to preclude the use of other gaging systems or dimensional control systems provided they are properly correlated, by the user, and yield comparable results with respect to conformance with the dimensional requirements of MA1370.
