ROK-IT gauges are truly spherical - part of a ball. They can be presented to the bore at any angle without struggling for alignment, and rocked over centre to check size.

When using a ROK-IT, there is no discernible friction, so you really can gauge 'size for size' - unlike conventional gauges where excessive friction can use a big chunk of the workpiece tolerance just to push the GO end into the bore. In other words, a conventional plug gauge can reject good components. ROK-IT doesn't.
