Ring Gages

Ring gages are used to evaluate the outside diameter of cylindrical workpieces. Ring gages are often used in pairs as go-no go gages. Rings with various forms, such as threads or splines are available.

Ring gages can be made with unilateral or bilateral tolerances. See Plug, Pin and Ring Gages.

Go-No Go Ring Gages

Ring gages may be called setting rings or setting ring gage when a master ring gage is used to calibrate instruments designed to measure bore diameters.
