      At = tensile stress area of bolt thread. D = basic major diameter of the thread. n = number of threads per inch. For steels of over 100,000 psi ultimate tensile strength, where: Esmin = minimum pitch diameter of external thread . The shear area of the external thread (bolt), which depends principally on the minor diameter of the tapped hole where:

      If the thread does not use the normal "coarse pitch" (e.g., 1.25 mm in the case of M8), then the pitch in millimeters is also appended with a multiplication sign, e.g. "M8×1" if the screw thread has an outer diameter of 8 mm and advances by 1 mm per 360° rotation.
