In some special cases, a little gaging time can be saved by putting the Go and NoGo diameters on a single gage member. A progressive plug, for example, is suitable for checking a short hole, which is open at both ends. Obviously, the hole cannot be deeper than the Go section of the plug.
Progressive style gages are usually in the taperlock style, but any of the designs can be made progressive.
