ASME B1.1-2003 UNIFIED INCH SCREW THREADS (UN and UNR Thread Form)

Size: 1 MB | Format: PDF | Publisher: ASME | Year: 2003 | pages: 190

This Standard specifies the thread form, series, class, allowance, tolerance, and designation for unified screw threads. (In order to emphasize that unified screw threads are based on inch modules, they may be denoted unified inch screw threads.) Several variations in thread form have been developed for unified threads; however, this Standard covers only UN and UNR thread forms. For easy reference, a metric translation of this Standard has been incorporated as Nonmandatory Appendix C. Nonmandatory Appendices A through E contain useful information that is supplementary to the sections of this Standard.
