ASME B1.5-1997 ASME Screw Threads

An American National Standard. The American Society of Mechanical Engineers (ASME). Revision of ASME/ANSI B1.5-1988. Date of Issuance: December 6, 1999. 121 p. This Standard provides for two general applications of Acme threads: namely, general purpose and centralizing.
The limits and tolerances in this Standard relate to single-start Acme threads and may be used, if considered suitable, for multiple-start Acme threads. The latter threads are used to provide relatively fast traversing motion when necessary.
