Thread Rings in standard sizes – Our standard thread ring gages (made in the USA) are adjustable and manufactured to an “X” tolerance per ANSIASME B1.2. These thread rings are used for checking male parts for quality. We offer these in UNC, UNF, & UNEF. Class 1A, 2A, & 3A. We keep many of these items in stock for fast delivery. We also offer an array of UNS specialty thread ring gages and standard metric ring gages with delivery time that rivals the industry! Custom threads, “Pre Plate Before Plate” , “W” tolerance thread gages are offered with little or no additional delivery time. We certify our gages to meet or exceed all published specifications and are traceable to the NIST (National Institute of Standards and Technology), and in compliance with (ISO) 10012-1 and ANSINCSL Z540-1. Uncertainties have been estimated at a 95% confidence level (K=2). Environmental controls are monitored to maintain 68 degree F and 50% maximum humidity. When necessary we offer ISO 17025, A2LA Calibrations through our 3rd party laboratories.

Application: Gaging internal threads. Our “Made in the USA” Class 2B & 3B Taperlock thread plug gages are manufactured to an “X” tolerance. Made of machine tool steel and traceable to NIST. 60 Degree Thread Types UNC – Unified National Coarse UNF – Unified National Fine UNEF – Unified National Extra Fine UNS – Unified National Special UNJ – for added tensile strength We certify our gages to meet or exceed all published specifications and are traceable to the NIST (National Institute of Standards and Technology), and in compliance with (ISO) 10012-1 and ANSINCSL Z540-1. Uncertainties have been estimated at a 95% confidence level (K=2). Environmental controls are monitored to maintain 68 degree F and 50% maximum humidity. When necessary we offer ISO 17025, A2LA Calibrations through our 3rd party laboratories.

Metric gages are tools for measuring and quality checks in metric dimensions. In addition to Unified Inch Screw Thread standards, we offer our full range of stock gages in sizes that conform to metric standards. We certify our gages to meet or exceed all published specifications and are traceable to the NIST (National Institute of Standards and Technology), and in compliance with (ISO) 10012-1 and ANSINCSL Z540-1. Uncertainties have been estimated at a 95% confidence level (K=2). Environmental controls are monitored to maintain 68 degree F and 50% maximum humidity. When necessary we offer ISO 17025, A2LA Calibrations through our 3rd party laboratories.

Standard Set Plugs – Our standard thread setting plugs (made in the USA) are truncated (unless otherwise requested) and are adjustable and manufactured to an “X” tolerance per ANSIASME B1.2. We also offer an array of UNS specialty thread set plugs and standard metric set plugs with delivery time that rivals the industry! Thread setting plugs serve the purpose of setting re-setting an adjustable thread ring gage to the proper size, as well as inspecting the ring for wear. Set plugs have a common pitch diameter for the full thread length of the GO or NOGO section. We certify our gages to meet or exceed all published specifications and are traceable to the NIST (National Institute of Standards and Technology), and in compliance with (ISO) 10012-1 and ANSINCSL Z540-1. Uncertainties have been estimated at a 95% confidence level (K=2). Environmental controls are monitored to maintain 68 degree F and 50% maximum humidity. When necessary we offer ISO 17025, A2LA Calibrations through our 3rd party laboratories.

Our Helicoil Taperlock Plug Gages, or Screw Thread Insert (STI) Gages (Made in the USA) are manufactured to an “X” tolerance, made of machine tool steel and traceable to NIST. Helicoil plug gages are used to inspect the hole prior to inserting a screw thread insert when repairing a threaded hole. We certify our gages to meet or exceed all published specifications and are traceable to the NIST (National Institute of Standards and Technology), and in compliance with (ISO) 10012-1 and ANSINCSL Z540-1. Uncertainties have been estimated at a 95% confidence level (K=2). Environmental controls are monitored to maintain 68 degree F and 50% maximum humidity.
