In general the proper torque spec is usually around % of the failure. Tightening torque for stud bolts in cold service ASTM A Grade L7 standard. The torque tables are built on specific assumptions regarding bolt and nut. Maximum Tightening Torques ; M8, Nm, Nm, Nm, Nm ; M10, Nm, Nm, Nm, Nm. The bolting standard will define whether the torque value is for a dry or lubricated stud/bolt thread. If a bolt is torqued rather than the nut, then the torque.

Tightening the screws with low rpm's without interruptions. Impact wrenches are not recommended for torquing series stainless steel fasteners. The. Torque Values Stainless Steel Bolt Table Chart ; , , , , ; 1/, , , , If a screw is lubricated, the friction in the threads and under the head is decreased and the relation between tightening torque and clamping force is changed.
