Thread Plug Gauges

A thread plug gauge is a precision tool used to check the internal threads of a nut or a threaded hole in a workpiece for compliance with specific thread standards. It is an essential instrument in manufacturing, machining, and quality control to ensure the accurate and proper production of threaded components. Thread plug gauges are designed to verify the dimensions, pitch, and profile of internal threads. Using a thread plug gauge involves inserting the gauge into the threaded hole or nut and checking for proper engagement. The Go end should pass smoothly through the threads, while the No-Go end should not. If the No-Go end engages, it indicates that the internal threads are out of tolerance.

Thread plug gauges are critical in industries where threaded components are used, such as automotive, aerospace, and machinery manufacturing. They help ensure the interchangeability and proper functioning of threaded parts within specified standards
