Thread ring gauge UNC GO, No. 3 × 48 ANSI/ASME B1.1 / 2A — Metav IndustryLine, hardened gauge steel

The Thread ring gauge UNC GO, No. 3 × 48 ANSI/ASME B1.1 / 2A is a hardened inspection gauge designed to verify external UNC threads to ANSI/ASME standards for production and incoming‑inspection use

• Hardened gauge steel construction
• Conforms to ANSI/ASME B1.1 standard
• Tolerance class 2A for external threads
• No. 3 × 48 pitch UNC specification

Standards-driven inspection for consistent pass/fail decisions

The ring is specified for external UNC threads according to ANSI/ASME B1.1, providing a straightforward GO/NO‑GO method that reduces subjective judgement on the shop floor. As a GO gauge, it confirms whether an external thread falls within the allowed limits of tolerance class 2A, enabling rapid acceptance in assembly or before coating. The direct benefit is a measurable reduction in sorting time and scrap, because thread conformity can be decided at the point of production without complex measurements.

Robust material and geometry for repeatable measurements

Manufactured from hardened gauge steel, the gauge resists wear in daily inspection cycles and preserves the mating profile over repeated use. The compact No. 3 × 48 geometry is optimised for UNC small‑thread applications, delivering stable engagement and minimal flex during checking. Repeatability is supported by the material choice and precise machining; this yields reproducible results batch after batch and extends the service life of the inspection tool, lowering total cost of ownership.

Workflow integration and traceable identification

The gauge is supplied with clear identifiers—SKU M315.943 and GTIN 4054469180007—for inventory control and traceability within quality management systems. Its simple GO verification complements visual inspection and torque testing stages, making it suitable for incoming goods checks, in‑process inspection and final acceptance. Using a purpose-made thread ring speeds throughput while maintaining documented conformity to the applicable standard.
