Because there are many variables that affect the torque-tension relationship, the only way to determine the correct torque is through experimentation under actual joint and assembly conditions. Bolt torque chart reference guides include Grade 2, B7, A307, A325, Grade 8, A490, and Grade 5.
10 Ιαν 2016 · Bolt tightening procedures are typically specific to the application and the type of bolt being used. Use the correct torque specifications provided by the manufacturer for the particular bolt and application. Lubricate the threads and the contact surface of the bolt and nut with an appropriate lubricant. Tighten the bolts in a star pattern, ...
