  • Dimensional Conformance. Direct tension indicators shall have the following characteristics inspected to ASME B18.18.2, page M-11, to the inspection levels shown:
    Characteristic
    Inside Diameter - B (Inspection Level)
    Protrusion tangential diameter - B (Inspection Level)
    Visual - C (Inspection Level)
    If verifiable in-process inspection is used
  • Nominal direct tension indicator sizes are intended for use with fasteners of the same nominal diameter.
