查询词典 pitch diameter of thread

Roundness tolerance of pitch diameter Roundness tolerance for a minimum of 345o circumferential arc of the pitch diameter shall not exceed .002 inch (0.051 mm) total, or one half the pitch diameter tolerance if the pitch diameter tolerance is less than .004 inch (0.102 mm); roundness tolerance of the remaining 15o maximum circumferential arc shall not exceed .004 inch (0.102) total, provided such tolerance does not result in excrescence on the thread flank.
