Torque bolts and nuts in a “CRISS-CROSS” sequence using a minimum of three torquing passes and the maximum bolt stress as defined. Tightening Torque Clamp Load (lbs.) Tightening Torque Clamp Load (lbs.) Once all pre-checks are completed. 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. Because of these existing variables, the only way to determine the correct torque is through experimentation under actual joint and assembly conditions. Clamp load calculated as 75% of the proof load when specified by the standard. Bolt circle is ANSI-B1 Torque Chart for ASTM A193 Grade B7 Studs in Ft./Lbs.
