Bolt proof load is defined as the maximum force that the material can support without experiencing permanent deformation. Although material properties vary, an approximate estimate of proof strength is .

The torque values can only be achieved if nut (or tapped hole) has a proof load greater than or equal to the bolt's minimum ultimate tensile strength. Clamp load calculated as 75% of the proof load when specified by the standard. ASTM A307 utilized 75% of 36,000 PSI. Torque values for 1/4 and 5/16-in series are in inch-pounds.
