Organization: ASME
Publication Date: 1 January 1984
Status: inactive
Page Count: 32
scope:

The purpose of this Standard is to establish uniform practices for standard screw threads with regard to the following:

(a) screw thread nomenclature, and

(b) letter symbols for designating features of screw threads for use on drawings, in tables of dimensions which set forth dimensional standards and in other records, and for expressing mathematical relationship.

This Standard consists of a glossary of terms, an illustrated table showing the application of symbols, and a table of thread series designations. Many of the terms and symbols specified in this Standard vary considerably from those of previous issues because ISO terms and symbols have been adopted where the intended definition is the same.
