(a) Shear test performed on pins ground to pin test diameter. The shear values are based on a minimum
shear strength of 125 ksi and the stress area at the test diameter.
(b) The ultimate tensile strength values are calculated on the basic pitch diameter of the external thread
and a tensile strength of 220 ksi.
(c) Maximum fatigue load is based on 46% of the ultimate tensile strength. Minimum fatigue load is 10%
of maximum fatigue load.
