Dưỡng kiểm ren ngoài GO chính xác (Tol. A) - G (BSP) 4" x 11

• Ring Gauge for functional inspection of threads in machining and maintenance environments.
• Incoming inspection and in process checks where fast pass or fail decisions are required.
• Verification of thread conformity without calculating pitch or diameter during production flow.
• Thread system context: use it on BSPP threads so the inspection matches the drawing callout.

Lưu ý Clean threads and tools before use, apply suitable lubrication for cutting operations, and stop if resistance rises sharply.

• Fast functional inspection without calculations or a full metrology setup.
• Supports consistent pass or fail decisions in incoming and in process checks.
• Helps prevent assembly issues caused by oversize or damaged threads.
• Useful for documenting repeatable quality checks in workshop routines.

• Does not provide a full dimensional report, only a functional limit check.
• Not suitable for high performance metrology tasks that require traceable calibration documentation.

1. Clean the thread and remove chips, dirt, and burrs before inspection.
2. Confirm the gauge type and tolerance class marking for the required check.
3. Apply the gauge gently by hand without forcing entry.
4. Stop if the gauge binds and clean the thread and gauge contact surfaces.
5. Evaluate entry behavior according to your inspection plan and record the result.
6. Apply light corrosion protection and store the gauge in its case.
