Notes
  • The thread conforms to ASME B1. 20.1 NTP threads.(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
