1.1.1This product is suitable for applications requiring extensive machining before such cold-forming operations as swaging, flaring, severe knurling, or thread rolling.

Note 1:Refer to Appendix X1 for additional applications information.

1.1.2Typically, product made to this specification is furnished as straight lengths. Sizes ¹/₂in. [12 mm] and under may be furnished as wire in coils or on reels when requested.

1.2The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

Note 2:Refer to Specifications B16/B16M and B140/B140M for copper-zinc-lead (leaded-brass) rod and bar for screw machine applications.

1.3This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
