Notes:

  1. Tolerance class 6H.
  2. Recommended minimum connecting hole application may require a different size.
  3. Tap drill depths given require use of a bottoming tap to produce the specified full thread lengths. Where standard taps are used increase tap drill depths accordingly.
  4. Preferred for diagnostic port applications.
  5. Preferred for cartridge valve applications.
