ASME Y14 pdf download SCREW THREAD REPRESENTATION
1 GENERAL
1.1 Scope
This Standard establishes requirements for pictorialrepresentation, specification,and dimensioning of screwthreads on drawings; it is not concerned with standardsfor dimensional control of screw threads. Informationhelpful in the design and selection of screw threadsto meet specific requirements is included in the B1series of the ASME Standards for Screw Threads (seepara. 1.3).
1.2 Application
Straight Unified inch (UN/UNR/UNJ form) and met-ric (M/MJform) screw threads are cmphasized in thisStandard in consideration of their wide use and generalpurpose applications.Thc same drafting practices applyto straight and taper threads，Acme，Stub Acme,But-tress，thread insert,and interference fit threads exceptfor differences noted.
