Thread Check's three wire thread measuring system can be used in a wide range of applications including certifying thread plug gages and set plugs and monitoring and controlling pitch diameter during thread fabrication. Thread Check’s holders are precision made to predetermined thread pitches. Thread measuring holders may be purchased with or without wires for companies that have existing wires. Wires are easily installed into the holders. Thread measuring holders are available in a wide range of inch, metric, and Acme sizes. Thread Check’s engineering department can design wire holders for multiple start threads, helical gears, worms, and other special thread measurement applications.
