Precision NOGO Dưỡng kiểm ren trong Tol. 2B Unified STI-Thread - UN 2" x 8

• Plug 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 UN 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.

What is the difference between GO and NO GO in thread gauging?

GO checks that the thread accepts the functional size for assembly, while NO GO checks that the thread is not oversize beyond the limit. The gauge gives a fast pass or fail result.

How do you prepare the thread before gauging?

Clean the thread, remove chips and dirt, and remove burrs that could block entry. A clean thread is required for a meaningful check.

How much force should you use on a thread gauge?

Use light hand force only and avoid tools that add torque. If the gauge binds, stop and investigate contamination or thread damage.

Where do you find the matching catalog for additional variants and reference data?

Does a gauge replace measurement of diameter and pitch?

A GO and NO GO gauge checks functional fit, not every geometric parameter. Use metrology tools if you need a dimensional report.

How do you store and protect gauges between checks?

Keep the gauge clean, apply light corrosion protection, and store it in the case. Avoid impacts that could damage the measuring faces.
