This paper was prepared to support supersession of MIL-S-8879C with Screw Thread Conformity Task Force selected industry standard AS8879C, published by the Society of Automotive Engineers (SAE). Other documentation changes will be covered by separate papers. Separate papers are anticipated for thread gaging issues, and thread gage calibration procedures. The STC-TF decided that the thread design standard needed to be completed before thread gage definition could be addressed. Thread gage definition has to be known before calibration procedures can be addressed.

This SAE Aerospace Standard (MA) provides recommended dimensional data for screw thread undercuts for straight “MJ” metric screw threads in accordance with MA1370.
The purpose of this SAE Aerospace Information Report (AIR) is to provide the aerospace propulsion industry with recommended assembly torque limits for commonly used aircraft propulsion system threaded fasteners when a common torque value per size is the objective.
