Maximum working loads have been astablished with a design factor of 5:1 using the maximum pin diameter, the resulting net area of the eye at the pin hole, and the expected ultimate tensile strength of C-1035 steel.
For any combination of tap size and pin diameter shown, the pin in double shear will develop the strength of the rod if both the rod and pin are made from steel having the same physical properties. The pin must be investigated for bending. If inadequate, a larger diameter pin must be selected.
If the pin is made from steel with physical properties lower in value than the steel used for the rod, the pin may not develop the strength of the rod and either shear or bend. A larger pin diameter would then be required.
