Choosing Van Keuren threaded gages to ensure your part is within your specified limits will have a positive effect on your production costs. Go and Not Go Thread Gages are used in manufacturing applications to provide the user with a quick and accurate method of inspecting and verifying that their threaded product meets the required specification.
Van Keuren threaded gages are ground, precision lapped and then meticulously inspected to every thread element. We make our gages to X-tolerance and we stock class 2A/2B for general applications such as bolt, nut, screw and similar threaded fasteners and class 3A/3B for applications where closeness of fit and accuracy of lead and angle of thread are important. Metric Thread Gages are stocked in standard 6H and 6g Tolerance.

Thread Identification Designations and Terminology and much more can be found in the Van Keuren Precision Measuring Tools Handbook No. 37. (EDP No: VKHANDBOOK37)
