Areas for the standard metric series of thread diameter-pitch combinations for aerospace externally threaded fasteners are established for the following conditions:
- a Area for ultimate shear stress or load in unthreaded shank.
- b Area for ultimate tensile stress or load in thread.
- c Area for stress durability test load in thread.
- d Area for stress-rupture test load at elevated temperature.
- e Area for tension-tension fatigue test load.
