View full detailsThread ring gauges are precision inspection tools used to verify external threads on bolts, shafts, and machined components. Available in metric (M, MF) and inch (UNC, UNF, BSP and more), they provide a fast pass/fail check against the standard, ensuring thread interchangeability without profile measurement.
This collection includes GO/NO-GO ring gauges in a range of pitches and tolerance classes for production and metrology. Options from Insize and Johs feature robust construction, high hardness for wear resistance, and dimensional stability for consistent repeatability.
Used by CNC machining shops, QC/QA departments, fastener manufacturers, and industrial maintenance teams for in-process inspection, incoming quality control, and final verification prior to assembly.

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.
