The production of Roman metal screw threads - extended version

Abstract

During the Roman period, small metal screw threads were used both as fastenings and to impart motion. This paper, which is an extended version of my previous article, will show that it is possible to produce metal screw threads using very simple technology. The tools and expertise to carry out this work is well within the skills of any competent metal worker. Small metal screw threads can be produced by semi- and unskilled labour, in a time frame that makes their production economically viable.
