Morris Miniature Fastener line, the company is well-positioned to serve medical device manufacturers, research laboratories, hobbyists, and many other industries that demand high precision miniature fasteners.

The J.I. Morris Miniature Fastener Division of Swissturn/USA stocks over 10 million screws, nuts, and washers from 0000-160 to 2-56 and Unified Miniature thread sizes from 0.5 UNM to 1.2 UNM. Included in our standard line are screws made to a variety of National Aerospace Standards. NAS721 (Miniature Fillister Head), NAS722 (Miniature Pan Head), NAS723 (100° Flat Head), and NAS724 (Miniature Binding Head) screws are usually available from stock. Flat head, flat fillister, oval fillister, and hex head screws are available off the shelf in brass and 303 stainless steel materials. Stainless steel nuts are available in thread sizes 0000-160 (say “quadruple-aught-one sixty”), 000-120 (say “triple-aught one twenty”), 00-90 (“double-aught ninety”), 0-80 (“aught eighty”), 1-72, and 2-56.
