- Inspect internal threads during setup, in process checks, or final inspection.
- Use it for acceptance decisions on threaded holes before assembly or coating steps.
- Apply the gauge by hand to evaluate fit and detect damage such as burrs or dents.
- Process: manual driving or assisted driving depending on your holder and machine setup
- Use: thread cutting, re tapping, and thread cleaning depending on condition
Note For consistent results, deburr the entry and keep the cutting area clean during use.
How do you use this gauge without damaging the thread?
Clean the thread first and apply the gauge by hand only. Stop at first abnormal resistance and investigate contamination or burrs before you decide on acceptance.
What does the designation M 29 x 1.5 tell you?
It states the exact thread form and size that the gauge is made for, including pitch information when it is part of the designation. Use only on matching thread designations.
What does tolerance 6H mean in practice?
It indicates the tolerance zone that the gauge is manufactured for. Use the gauge together with the correct drawing and standard so the acceptance decision matches your specification.

How do you handle borderline results?
Repeat the check after cleaning and keep handling consistent. If the feel changes between checks, inspect the thread for damage, plating build up, or deformation.
How do you store and protect the gauge?
Keep it clean and lightly protected against corrosion. Store it in a protective case and avoid contact with other hardened tools to prevent nicks.
