Learn more about ring gages' primary functions- inderect and direct gaging.
In the high-precision world of industrial manufacturing, machinists implement a broad range of measuring tools. One of the most vast and versatile is the handheld gage. Handheld gages range from the familiar digital micrometer to tools as basic as a ruler, and everything in between. A member of the handheld family, the ring gage is a cylindrical measuring device with a precision lapped, nearly perfect geometry and a precisely determined internal diameter. Ring gages have two primary functions in manufacturing: a point of reference for setting other measuring instruments, or indirect gaging, and checking the size and roundness of manufactured parts, or direct gaging.
