WebIn tightening a bolt stress is induced as a result of the bolt tension and bolt torque.. The combined resulting shear stress is calculated as follows F Bolt Tension (N) T f = Thread torque (N.m) A r = Thread Root Area (m 2) d r = Thread Root diameter This formula is relatively conservative. http://steeljis.com/roymech/keyways/key_strength.php
