A class 1 is a looser fitting, general-purpose thread; a class 3 is the closer-toleranced aerospace standard thread. (The individual tolerances and sizes for the various classes are given in the SAE Handbook (ref 4).) Forming of Threads. Threads may be cut, hot rolled, or cold rolled. The most common manufacturing method is to cold form both ...
ISO 965-3:1980 ISO general purpose metric screw threads - Tolerances - Part 3: Deviations for constructional threads; ISO 1502:1996 ISO general-purpose metric screw threads - Gauges and gauging; Threads produced to this standard are interchangeable with threads produced to the metric standard ANSI/ASME B1.13M Metric Screw Threads: M Profile.
