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.
