Committee Listing: For a listing of ASME Codes and Standards Development Committees and their charters, visit the Codes and Standards Web site at http://cstools.

Conformity Assessment: For a listing and description of ASME Conformity Assessment (accreditation, registration, and certification) programs, visit the Codes and Standards Web site at www.

Staff Contacts: To obtain the ASME staff contact information for a Codes and Standards Development Committee or a Conformity Assessment program, visit the Codes and Standards Web site at

Schedule of Meetings: Meetings of Codes and Standards Development Committees are held periodically to consider the development of new standards and the maintenance of existing standards. To search for scheduled meetings of Codes and Standards Development Committees, by date or by keyword, visit the Codes and Standards Web site at


An important element of ASME's accredited standards development procedures is the requirement that all proposed standards actions (i.e., new codes and standards, revisions to existing codes and standards, and reaffirmations of existing codes and standards) be made available for public review and comment. The proposed standards actions currently available for public review are announced on ASME's Web site, located at http:// Reviewpage.cfm.

The Web site announcements will provide information on the scope of the proposed standards action, the price to order a hard copy of the proposal, the deadline for submittal of public comments, and the ASME staff contact to whom any comments should be provided. Some proposed standards actions may be available directly from the Web site; hard copies of any proposed standards action may be obtained from:

New Edition! ASME B1.1-2003 Unified Inch Screw Threads

(UN and UNR Thread Form). This standard specifies the thread form, series, class, allowance, tolerance, and designation for unified screw threads.

The world literally hangs by a thread whether it be for automotive, aerospace, off-road equipment, or any other application that requires the joining of parts together. Although this concept is not new, the latest issue of the standard that governs inch screw threads is ASME B1.1. This standard specifies the thread form, series, class, allowance, tolerance, and designation for unified screw threads. This standard only covers UN and UNR threads forms. This new edition contains revisions to some of the listed values for "Limits of Size for Standard Series of Threads" and "Limits of Size of Special Series of Threads." These changes are the result of the application of the revised rounding rules established in ASME B1.30-2002 and some corrections for calculation errors. With this revision, all parties calculating both standard and special series threads will derive precisely the same values. Additionally, the effects of coating on threads have been explained in more depth.

For easy reference, a metric translation of this standard has been incorporated as Appendix C. Appendices A through E contain useful information that is supplementary to the sections of this standard.
