Three different sets of threading gauges. The uppermost gauge is an ISO metric pitch gauge, the larger gauge in the center is for measuring the Acme thread form, and the lower gauge is for Whitworth screws.
A thread gauge,[1] also known as a screw gauge[2] or pitch gauge,[3] is used to measure the pitch or lead of a screw thread.
Thread pitch gauges are used as a reference tool in determining the pitch of a thread that is on a screw or in a tapped hole. This tool is not used as a precision measuring instrument, rather it allows the user to determine the profile of the given thread and quickly categorize the thread by shape and pitch. This device also saves time, in that it removes the need for the user to measure and calculate the pitch of the threaded item.
