Abstract
A method for achieving a target joint preload includes identifying a thread pitch of a first fastener element used to secure two components together. The first fastener element is passed through the two components and a second fastener element is threaded onto the first fastener element. A tightening torque is applied to the second fastener element, which is measured as the trial tightening torque. A loosening torque is applied to the second fastener element, which is measured as the trial removal torque. A required tightening torque that is required to be applied to the second fastener element to achieve the target joint preload is calculated using only the thread pitch, the trial tightening torque, the trial removal torque, and the target joint preload.
