Web23 iul. 2024 · According to the chart above, the recommended tightening torque for an M12 bolt with a 10.9 bolt grade would be 114.0 Nm. It’s important to note that higher bolt grades require a higher torque to get more clamping force. Bolt friction The final key factor is determining the maximum torque for your bolt is friction. WebDue to preload uncertainty, the actual preload applied to the bolt may be more or less than the nominal value. Due to preload relaxation, there will be some loss in the preload after the joint is installed. The maximum value of preload accounts for the preload uncertainty, and is calculated as: F PL.max = (1 + % uncrt ) · F PL.nom =.
