Title:Areas for Calculating Stress Or Load Values for Metric Mj Externally Threaded Fasteners
Issuing Committee:E-25 General Standards For Aerospace And Propulsion Systems
Scope: This standard specifies the areas to be used in calculating stress or load values for use in metric externally threaded fastener procurement specifications and for information of designers. Areas for the standard metric series of thread diameter-pitch combinations for aerospace externally threaded fasteners are established for the following conditions: area for ultimate shear stress or load in unthreaded shank; area for ultimate tensile stress or load in thread; area for stress durability test load in thread; area for stress-rupture test load at elevated temperature; and area for tension-tension fatigue test load.
