Thread gauge M8x1.25 6H Mt 60deg

The internal thread gauge is designed to measure the quality assurance and acceptance criteria for internal threads, such as machined holes. It is suitable for situations where you want to ensure that the thread is manufactured to the correct dimensions and meets standard tolerances.

Technical specifications & features

- Thread: M8 × 1.25 (nominal diameter 8 mm, thread pitch 1.25 mm)
- Tolerance class: 6H - standard ISO/DIN for metric threads
- Standard(s) conformance: ISO/DIN 13 (metric threads)
- GO / NO-GO measurement: The tool tests both that the thread is at least at the minimum dimension (GO) and that it does not exceed the maximum permissible dimensions (NO-GO). If the GO end screws in easily but the NO-GO end does not, the thread is in compliance with the standard.
- Material: Hardened tool steel
- Purpose: Internal thread inspection - to ensure that the thread of the hole or groove meets M8×1.25 specifications before assembly or mass production.
