The torque required for a 3/4" dry steel bolt with 0% lubrication to achieve this tension can be calculated as, Tdry = (0.2) (20000 lb) (0.75 in) (1/12 ft/in) (1 - (0%) / (100%)), The proof load for a M30 metric bolt grad 8.8 is 337000 N. The torque required to achieve this tension with a dry bolt with 0% lubrication can be calculated as, Tdry = (0.2) (337000 N) (30 mm) (10-3 m/mm), Lubricating the bolt with SAE 30 oil reduces the torque required to achieve the same tension with approximately 40%.
