http://portal.ku.edu.tr/~cbasdogan/Courses/MDesign/course_notes/ScrewStresses.pdf WebbScrew threads are a clever bit of engineering. If you straighten one out you will find that it is a simple taper varying between about 4° (smallest screws) to about 2° (larger screws). It is no coincidence that Stephen Morse's 'self-holding' taper has an included angle of about 3°.
