WEBDue to many variables that affect the torque-tension relationship like human error, surface texture, and lubrication the only way to determine the correct torque is through experimentation under actual joint and assembly conditions.
SAE Bolt Torque Chart – Grade 2, Grade 5, Grade 8
WEBThe charts below show the ideal tightening torque for each bolt grade for a variety of sizes. The size column also includes the thread count. Identify the grade, size, and thread density of your bolts and refer to the tightening torque columns.
WEBU.S. Recommended Bolt Torque Table. ** Fine thread figures are for 1-14. Grade 2, 5, and 8 values are for plated bolts.
WEBTorque specifications, especially for critical joints, should be determined under actual assembly conditions due to the many variables involved which are difficult to predict and do affect the torque-tension relationship.
