Notes
  • The thread conforms to ASME B1. 20.1 NTP threads as described in Section 10. (The only exceptions are small male and female plain face threaded flanges which use NPSL locknut threads)
  • Class 300 and higher threaded flanges are counter-bored. Threads are chamfered to the counterbore at an angle of 450 (approx)
  • Weights are based on manufacturer's data and are approximate
