Notes:

  1. Refer to ANSI/ASME B16.5 for notes, pressures, and minimum design requirements.
  2. Any column with "-" relate to a note in the standard or is not be covered in the standard.
  3. Data columns from the reference standard may have been omitted.
  4. US units are inches, Metric Units are millimeters.
  5. Studs are measured parallel to the axis (L) from the first to the thread without the chamfers (points).
  6. Hex bolts are measured from under the head to the top of the bolt.
