View full detailsThread gauges provide fast GO/NO-GO inspection of whether a thread is within tolerance. Plug gauges (male) check internal threads (nuts, holes); ring gauges (female) check external threads (bolts, shafts).
This collection covers metric (M, MF), inch (UNC, UNF, UNEF, BSP), trapezoidal (Tr) and specialty gas-cylinder threads (17E/25E, ISO 11363), in multiple tolerance classes. Solutions from Insize & Johs with hardened, wear-resistant surfaces.
Ideal for machine shops, CNC and QC departments where a quick pass/fail decision is needed 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.
