External thread inspection can seem confusing and, in some cases, frustrating. There is a wide variety of inspection tools available for external threads. They may be inspected with functional thread ring gages as pass/ fail inspection. They may also require some type of actual measured value that would require pitch micrometers, thread measuring wires, tri-rolls, laser, or image based measuring systems. All of these measuring tools have various strengths and weaknesses. As with all measuring tools, knowing what you need to measure and the measuring device capabilities is critical to successful and accurate inspection of the product produced.
