Thread Check, Inc. offers library sets of the three wire thread measuring system for fast and accurate thread measurement on a variety of measuring instruments. Thread Check's specially designed holders and wires make thread measurement fast and accurate. Our thread measuring holders are fitted with certified full length thread measuring wires that meet or exceed the requirements of ASME B89.1.17‐2001, ANSI/ASMEI B1.2 and ANSI/ASME B1.16M as well as Federal Spec. GGG‐W‐366B. All wire holder sets include the actual wire size, NIST traceable number and constant required to determine the correct pitch diameter. Standard holder and wire library sets are available in a full library set that includes 5 to 80 TPI sizes**. The partial library set includes 6 ‐ 36 TPI sizes**. Both library sets are supplied in wooden cases for convenient access. Optional ISO 17025 calibration is available.
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. Custom library sets are priced on request.
