do not have the exact answer but just suggesting one thing that consider the fact that initial threads engaged are the ones which bear maximum load So you may want to focus on first few Screw Thread Design Fastenal Screw Thread Design Screw Thread Fundamentals A screw thread is defined as a ridge of uniform section in the form of a helix on either the external or internal surface of a cylinder Internal threads refer to those on nuts and tapped holes while external threads are those on bolts studs or screws The thread form is the configuration of the thread in an axial plane or Pull Out
