1 = Bolt material grades 8.8 (metric) and ASTM A193 B7 (Imperial) or similar2 = AF size is based on heavy series nuts3 = Bolt tension equates to a bolt stress of 60% of the minimum yield strength4 = Torque figures detailed are based on 60% of the minimum bolt yield stress

For grade 10.9 bolts, please add 47% to value stated for grade 8.8 boltsFor grade 12.9 bolts, please add 72% to value stated for grade 8.8 bolts

RECOMMENDED TORQUE VALUE CHART Use this chart as a guideline for the correct torque to be applied to standard size metric and imperial bolts in grades 8.8 (metric) and ASTM A193 grade B7 (imperial) or similar. The torque figures are calculated in both metric (Nm) and imperial (lbf.ft) values using a choice of three commonly used bolt thread lubricants. Always consider the coefficient of friction applicable for the chosen bolt lubricant. For grade 10.9 bolts add 47% and grade 12.9 bolts add 72% to the figure detailed against the relevant A193 B7 or 8.8 grade stud bolt size. Remember these torque values are for guidance purposes only! Always check the equipment/bolt manufacturer for the actual torque required and specified for bolted components within the particular equipment design.
