Relates to dies and die-nuts for cutting both parallel and taper pipe threads of Whitworth form in accordance with AS 1721, and in the following series and size ranges: G series from 1/16 to 2¼; RL series from 1/16 to 2; R series from 1/16 to 2. Covers terms and definitions, materials and properties, dimensions and tolerances, together with testing and marking requirements.

This standard specifies requirements for circular machine and hand screwing dies and die-nuts for cutting fastening and sealing pipe threads in accordance with AS 1722.NOTES:1. During the transition period of the ISO metric hexagon series, hexagon die-nuts may be supplied with general dimensions in accordance with Appendix A which represents current practices soft-converted into metric units. If the purchaser specifically requires die-nuts with ISO metric hexagons as given in Tables 2.3 and 3.3, he should indicate this in his enquiry or order.2. The designation of pipe threads comprises the series designation followed by the nominal size (bore) in inches. For further information, see AS 1722, Parts 1 and 2.
