Screw Thread Representation
|Publication Date:||1 January 1978|
This document establishes standards for pictorial representation, specification, and dimensioning of screw threads on drawings; it is not concerned with standards for dimensional control of screw threads. Information helpful in the design and selection of screw threads to meet specific requirements is included in the B1 and B2 series of the American National Standards for Screw Threads (see Appendix A). Only certain metric thread references are shown in this standard.
