For inspecting larger diameters and excessively long depths, the IT-6000 and the PD-6000 are limited. Use an IT-6001 for inspecting taper on tapered threads with greater than 9″ diameters. For diameters greater than 6″, a PD-6001 will inspect pitch diameter on straight threads and seal grooves. By stacking extension rods, these gages will inspect diameters up to 36″ and are not limited by depth.
