Here, Dr Bill Eccles, Bolt Science looks at the basic principles of screw threads, including their tolerances and allowances which are applied, as well as the problems associated with this. The basic profile is the theoretical profile of the thread. An essential principle is that the actual profiles of both the nut and bolt threads must never cross or transgress the theoretical profile. So, bol...
