A mis-made NGT thread can be a product liability issue. Table 1, Column 9, Change tolerance on LPC from 0/–3 to 0/–3,18 Table 1, footnote (c), Replace –5 mm with 0/ –5 mm Figure 7 (b), Replace as shown [decrease groove depth from 6,4 (0.25) to 1,6 (0.062)] Note: This screw chart is not comprehensive of all available standard threads as provided by the standard. (ref) Do not use these values for standard metric internal thread design. These thread sizes and classes represent bolts and screws, as well, as other standard external threads. Thread Ring Gages also referred to as thread ring gauges are used to check the outside major diameter and pitch diameter limits on threaded parts. We specialized in the design, manufacture & supply of API product specification thread gages for inspection of oil & gas related industry product connections such as required by the API product specifications 5CT, 5B, 5D. Pitch Dia d2=D2 2. They can be produced to any specification up to 250mm diameter. (ref) pitch diameter go plug gage 6h tolerance pitch diameter not go plug gage 6h tolerance mm in.
