Precision Dưỡng kiểm ren trong Tol. 3B Unified coarse STI-Thread - UNC số 12 x 24
Use this plug gauge to verify that an ren trong is within tolerance before assembly. It is typically used in quality control, incoming inspection, and process monitoring.
Use it as a comparative check; if the thread feels abnormal, investigate burrs, plating, or deformation before rejecting parts. UNC indicates a Unified inch thread with a coarse pitch series.
- Inspect ren trong 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: cắt ren, taro lại ren, and làm sạch ren depending on condition
Lưu ý For consistent results, deburr the entry and keep the cutting area clean during use.
- Fast pass fail decision without complex measurement equipment
- Supports stable process control in serial production and incoming inspection
- Helps identify handling damage such as burrs, dents, or thread pull out
- Reduces assembly issues by filtering non conforming threads early
Hạn chế
- Not suitable for determining the exact deviation of thread geometry; it is a limit check.
- Requires clean threads and careful hand feel; forcing can damage the gauge and the part.
- Clean the threaded hole and remove oil, chips, and burrs from the entry.
- Visually check the thread for dents, plating build up, or deformation.
- Identify the GO and NO GO sides when the gauge has separate ends.
- Insert the GO side by hand and turn with light finger force until it seats or stops.
- Try the NO GO side by hand and stop as soon as resistance increases.
- If the feel is inconsistent, clean again and repeat the check with the same handling.
- Record the result and protect the gauge with a light corrosion protection film after use.

- Type: Dưỡng kiểm ren trong for ren trong
- Tolerance: 3B
- Thread system: UNC
- 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 UNC số 12 x 24 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 3B 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.
- Where can you find catalog information for this product family?
- Use the product catalog for overview tables and selection context. VG 23 catalog as PDF
- 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.
