Nettet12. sep. 2006 · New formulas are developed for the torque-tension relationship, various torque components, and breakaway torque values in threaded fastener applications. The three-dimensional aspects of the lead helix and thread profile angles and the kinetic and static friction coefficients are all taken into account. Two scenarios of the contact … NettetUsing a previously used K-factor linear equation, we calculated a 49.8% variation between torque-tension. To yield lower variations in the future, we recommended a Motosh …
