WebThe 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) = 2024 (Nm) Lubricating the bolt with SAE 30 oil reduces the torque required to achieve the same tension with approximately 40%.
