Thread Ring Gauge UNF GO No. 2 × 64, ANSI/ASME B1.1 / 2A — Metav IndustryLine, hardened gauge steel

The Thread Ring Gauge UNF GO No. 2 × 64 is a GO-type inspection gauge for fast verification of external UNF threads to ANSI/ASME B1.1 standards on production and inspection benches

• Hardened gauge steel construction
• ANSI/ASME B1.1 compliance
• Tolerance class 2A for accurate checks

Ensure threads meet specification with clear pass/fail decisions

This GO ring offers a straightforward, rational inspection method based on the go/no‑go principle. Manufactured to ANSI/ASME B1.1 and specified as 2A, the gauge verifies that external UNF threads of No. 2, 64 tpi are within the permissible major diameter and form limits. The fixed GO profile provides an immediate, unambiguous assessment in repeat inspections, reducing scrap and rework while accelerating throughput on the shop floor. The documentable nature of a GO check supports quality records and process control.

Durable materials that keep measurement uncertainty low

Made from hardened gauge steel, the ring is designed for long service life and wear resistance under frequent use. The material choice and hardening process maintain the gauge geometry, preserving the fit and therefore the measurement reliability over many inspection cycles. Lightweight at approximately 0.1 kg, the ring is easy to handle during serial checks, yet sufficiently robust to resist distortion; this balance improves repeatability and lowers the influence of handling on results.

Integrates into standard inspection routines and documentation

The GO ring simplifies routine checks in production, incoming inspection and maintenance work. Its single‑function design makes it ideal for quick acceptance testing of external UNF threads, supporting efficient assembly processes and minimising machine downtime. The product is provided with clear identification (SKU and GTIN) to ensure traceability within inventory and quality systems, assisting audits and part lot control while fitting seamlessly into existing inspection workflows.

FAQ

What does the ‘GO’ designation mean for this gauge?
The GO designation indicates the ring is a GO-type thread ring gauge used to check that external UNF threads (No. 2 × 64 tpi) are within the maximum material limit; the Thread Ring Gauge UNF GO No. 2 × 64 confirms a part will assemble when the ring passes.

Is this gauge compliant with recognised standards?
Yes, the ring is manufactured to ANSI/ASME B1.1/B1.2 requirements and specified as tolerance class 2A, ensuring compatibility with standard UNF thread specifications.

What materials is the ring suitable for checking?
The gauge is intended for inspection of external UNF threads irrespective of the parent material; its hardened gauge steel construction gives wear resistance suitable for repeated checks on metal components.

How should the ring be used in a production environment?
Use the ring as a quick pass/fail check on external UNF threads during production or incoming inspection; a positive GO result from the Metav IndustryLine ring indicates the thread meets the permitted maximum material profile.

Can the ring be traced for quality records?
Yes, the Thread Ring Gauge UNF GO No. 2 × 64 (SKU M315.942.F) can be recorded in traceability systems using its SKU and GTIN for inventory and audit purposes.
