About Us

The J.I. Morris name has been recognized as a leader in the miniature fastener field for more than 70 years.  Originally founded in 1920, Morris pioneered methods for producing quality miniature fasteners and participated in writing miniature screw thread standards.

In September of 2017, Swissturn/USA purchased the miniature fastener line from J.I. Morris and moved production from Morris’s original home in Southbridge, MA to Swissturn’s world class facility in Oxford, MA.

With over 30 CNC Swiss-type screw machines, Swissturn manufactures millions of precision parts each year, including the J.I. Miniature Fastener line.

Swissturn is employee-owned and is ISO9001 registered.

Very few people have a comprehensive knowledge of miniature screw threads. You can become one of them by carefully studying the information available on our website Included is data from standards developed by several organizations (many of which our company helped to create) and information generated by us from applicable formulas, directives and experience. It is important to remember that many standard calculations, such as feeds and speeds, are not applicable to miniatures. Also, increments as small as .001" can make a big difference in the ability to produce a satisfactory result.
