Thread ring gauge UNC NOGO, 9/16-12 ANSI/ASME B1.1 / 2A — Metav IndustryLine

A Thread ring gauge UNC NOGO, 9/16-12 (2A) designed for rapid Go/No‑Go verification of external UNC threads in production and quality inspection.

• ANSI/ASME B1.1 compliant thread form
• Hardened gauge steel for wear resistance
• NOGO design for Go/No‑Go verification
• Tolerance class 2A for external threads

Rapid, reliable Go/No‑Go inspection for production

This NOGO ring is optimised for efficient thread checks on series parts, converting dimensional data into an immediate pass/fail decision. The 9/16-12 UNC geometry paired with ANSI/ASME B1.1 adherence provides a clear acceptance criterion, shortening inspection cycles and reducing rework. Using a defined 2A tolerance ensures compatibility with common external thread classes, so measurement decisions are consistent across operators and shifts.

Built for longevity and repeatable results

Manufactured from hardened gauge steel, the ring resists wear and maintains the original thread form through extended use, which prolongs service intervals and lowers lifetime costs. The NOGO function prevents oversized threads from being accepted by design: the ring should not fit an out-of-tolerance external thread, delivering an unambiguous control point for quality assurance. The compact mass and robust construction make the tool straightforward to handle while preserving dimensional integrity.

Suitable for workshop and production environments

Engineered for metalworking and inspection benches, this ring gauge fits into standard QC procedures and is appropriate for calibration cycles and incoming inspection. With a standard 12 tpi pitch and common UNC profile, it integrates into test plans for fasteners and assemblies in mechanical engineering and maintenance contexts. The nominal weight of 0.4 kg reflects a solid, portable tool that balances stability with ease of handling for repetitive checks.
