Thread Ring Gauge UNC GO, 1 1/4" x 7 – ANSI B1.1, 2A by Metav IndustryLine

A Thread Ring Gauge UNC GO, 1 1/4" x 7 designed for fast verification of external UNC threads to the ANSI/ASME B1.1 standard

• Hardened gauge steel construction
• ANSI B1.1 / B1.2 compliant
• GO ring for UNC 1 1/4" x 7 thread
• Tolerance class 2A for external threads

Reduce inspection time with a one-step GO acceptance check

The GO ring purpose is straightforward: permit only threads that meet dimensional acceptance into production. By using a dedicated GO ring, tolerance evaluation turns into a quick pass/fail operation, improving throughput in assembly and incoming inspection. The gauge cuts decision time on the shop floor, supplies reproducible results and minimises subjective judgement during thread acceptance, which is essential in high-volume or repetitive inspection tasks.

Built for longevity and repeatable performance

Constructed from hardened gauge steel, this ring gauge resists wear and maintains its form under frequent use. Heat treatment and precision finishing reduce the need for frequent replacement, supporting continuous production runs and lowering long-term tooling costs. The rugged material and careful manufacturing ensure that the gauge preserves its acceptance limits over many inspection cycles, so measurement integrity remains consistent across batches.

Conformance and traceability to support quality systems

Manufactured to ANSI/ASME B1.1/B1.2 and supplied as a GO gauge in tolerance class 2A, the product aligns with common engineering specifications for UNC threads. The clear specification facilitates documentation in quality records and supports traceability within audit trails. For organisations that rely on documented evidence of correct inspection methods, the gauge integrates simply into existing quality workflows and inspection plans.
