How To Measure Hex Holes With Go & No Go Gages

go & no go gages

During a manufacturing process, it is often a challenge to measure hexagonal (hex) holes. Hex holes are even harder to measure if they are internal (inside a compartment or object) because of varying reasons such as getting the right tools. This is the reason why Go & No Go gages are so useful in such processes. Typically, to make hex holes, a pilot hole is first done and then the sides are cut out to create the hex shape. The first stage usually presents few problems as a pilot hole is relatively easy to gage (such as with an air gage for example). The harder part comes when you are doing the sides as these usually determine how well the hex hole will fit into its intended part.
