Thread plug gauges are used for fast GO/NO-GO inspection of internal threads, verifying that pitch and diameter stay within tolerance. Available in metric (M, MF) and inch (UNC, UNF, BSP and more) threads, they are essential metrology tools for reliable quality control in machining and production.

Offered in GO/NO-GO configurations, multiple tolerance classes, and hardened wear-resistant options for long service life. Choose solutions from Insize & Johs for consistent repeatability and standards compliance.

Well suited for machine shops, turning and CNC operations, and QC departments where quick acceptance decisions are required without time-consuming measurement.

Thread Gauges

The thread gauges (thread gauges) are standard verification tools used to check the accuracy and compatibility of threads on screws and nuts. They are based on the "Go / No-Go" method, ensuring that the thread is within the specified tolerance limits for correct assembly and operation of the components.

Types: They are classified into standard rings (ring gauges) for external threads and standard plugs (plug gauges) for internal threads.
Applications: Essential in mass production, precision machining, and quality control of fastening components.
Standards: Manufactured according to international systems such as Metric (M), Whitworth (BSP) or Unified (UNC/UNF), from hardened high-strength steel.
