General

This standard covers the dimensional specifications for American Standard Screw Threads applicable to bolts, machine screws, nuts, tapped holes, and other threaded parts. It is a revision of the original American Standard approved in May, 1924, by the American Standards Association. The changes and additions included are based on the requirements of industry as reflected by comments received since the release of the 1924 publication and also upon the information obtained through and extensive survey of American industrial screw thread practice conducted in 1931 by the Sectional Committee on Standardization and Unification of Screw Threads with the cooperation of the National Bureau of Standards.
