A GUIDE TO TORQUE VALUES
It should be understood that the subject of torque tension loading is beyond the scope of this document. The
information here supplied is an acceptable guide for normal conditions; for critical applications, however,
further information and research will be necessary.
In preparing this guide to torque values, the following basic assumptions have been made:
(a) bolts and nuts are new, standard finish, uncoated and not lubricated*
(b) the load will be 90% of the bolt yield strength
(c) the coefficient of friction (μ) is 0.14
(d) the final tightening sequence is achieved smoothly and slowly, until the torque tool indicates full torque
has been obtained.
* If lubrication has been applied to the bolt and/or the nut (other than the normal protective oil film), multiply
the recommended torque by the appropriate factor
