Thread load calculation
http://steeljis.com/roymech/screws/thread_calcs.php WebMar 13, 2009 · From there it's p/a. Once you have the load at yield apply tolerance for lubrication, surface finish and variations in material and torque application. As a rule of thumb I apply 20%, but all of your factors should be considered. It seems what you are looking for is "failure by thread pullout."

WebAbstract. The distribution of load along the length of a nut is not uniform owing to the strains set up in the bolt and nut under load. These strains are analysed and the load distribution along the thread helix deduced. It is shown that the load may be taken as concentrated at mid-depth of the threads. In the normal bolt and nut case the ... WebBolted Joint Design - Fastenal
