Thread ring gauge UNC GO — 1 3/8" x 6, ANSI/ASME B1.1, 2A (Metav IndustryLine)

A Thread ring gauge UNC GO, 1 3/8" x 6, 2A designed for reliable go/no-go inspection of external UNC threads in workshop and production quality control

• Hardened gauge steel for long service life
• Conforms to ANSI/ASME B1.1 thread standards
• Tolerance class 2A for precise acceptance control
• Size 1 3/8" x 6 UNC for common industrial threads

Faster acceptance checks with consistent pass criteria

A GO ring is the quickest way to verify whether an externally threaded part meets the specified form and major diameter limits; the GO gauge presented here confirms that a thread is within tolerance class 2A, allowing immediate acceptance for assembly or onward processing. The item measures a standard coarse UNC series with a pitch of 6 threads per inch, which makes it suitable for common fastener inspections in maintenance, fabrication and incoming goods. Using a dedicated ring for the “go” condition reduces decision time on the shop floor and avoids ambiguous measurement sequences, thereby improving throughput without sacrificing traceability.

Built to withstand repetitive use in industrial environments

Manufactured from hardened gauge steel, the ring offers robust wear resistance and dimensional stability under frequent handling. The heat-treated material minimises profile wear, so the gauge retains its acceptance limits over many inspection cycles and requires less frequent replacement. With a mass of 0.7 kg, the tool is easy to handle yet solid enough to avoid accidental distortion during use. The compact footprint of the ring supports quick fixture checks and portable inspection routines, while the hardened finish simplifies storage and reduces the risk of surface damage that could affect fit.

Standards, traceability and procurement-ready identifiers

Compliance with ANSI/ASME B1.1/B1.2 ensures compatibility with established thread forms and allows integration into formal quality systems and inspection plans. Identification details such as SKU M315.964 and GTIN 4054469180519 support clear inventory control and traceable procurement, while the tariff number 90173000 facilitates customs and logistics documentation. For quality managers, the combination of standard conformity and robust material choice supports documented acceptance criteria and supplier qualification processes, simplifying audits and repeat orders for production or maintenance needs.
