WebAfter half a day or so, the release torque can be typically up 10% greater than the tightening torque. This is due to a number of effects including embedding of the contact surfaces and changes in temperature affecting the friction conditions. Such effects typically increase the friction and hence a greater release torque is required.

WebThe above chart provides reasonable tightening values, but they are not the optimum tightening values for every application. A far better way to establish a tightening torque for a particular application is by conducting a simple study. To determine the ideal tightening torque for any particular application joint, do the following: 1. WebApproximately 90% of the applied torque is employed in overcoming friction, 50% at the bearing face of the nut and 40% between the mating threads. It can therefore be seen that only something in the order of 10% effort is employed inducing axial load in the bolt.
