Thread ring gauge UNC GO, 9/16" x 12, ANSI/ASME B1.1 – 2A (Metav IndustryLine)

The Thread ring gauge UNC GO, 9/16" x 12 – 2A is a precision inspection gauge designed to verify external UNC threads to ANSI/ASME tolerances in production and incoming‑inspection environments.

*Hardened gauge steel for durable inspection
*ANSI/ASME B1.1 compliant 9/16" x 12 thread check
*Tolerance class 2A for GO verification accuracy
*Compact 0.2 kg mass for easy handling

Consistent compliance for faster quality decisions

The GO ring is manufactured to meet ANSI/ASME B1.1 requirements and the 2A tolerance class, providing a clear, objective pass criterion for external UNC threads. Using a dedicated GO gauge reduces subjective judgement during manual checks and accelerates decision making on the shop floor. The result is fewer rework loops and more reliable throughput, because the inspection outcome is defined by an accepted standard rather than visual estimation.

Built for workshop durability and simple handling

Made from hardened gauge steel, the tool resists wear and keeps the measuring form stable over many inspection cycles, which lowers total cost of ownership. Its compact mass (0.2 kg) and hand‑friendly profile support quick, repeatable checks at the machining centre or assembly bench. The robust construction translates directly into predictable service intervals and less downtime for gauge maintenance.

Practical use in production and quality control

This GO ring gauge is suitable for routine production sampling and incoming part verification where UNC threads 9/16" x 12 are specified. The gauge provides a single, unambiguous GO test for external threads; when the thread enters the gauge smoothly, the part conforms to the specified 2A tolerance envelope. Integration into a standard inspection routine is straightforward and supports traceable quality records when combined with internal process documentation.

FAQ

What thread size does this gauge check?
The ring verifies external 9/16" x 12 UNC threads in accordance with the ANSI/ASME B1.1 standard.

Is the gauge suitable for production sampling?
Yes, the GO ring gauge is designed for routine production and incoming‑inspection sampling to confirm parts meet the 2A tolerance class.

What material is the gauge made from?
The gauge is manufactured from hardened gauge steel, ensuring wear resistance and long‑term dimensional stability.

How does the GO gauge indicate conformity?
Conformity is determined by a pass/fail check: if the external thread enters the GO ring freely, the part meets the specified 2A limits.
