Thread ring gauge UNC NOGO, 3/4 x 10 ANSI B1.1 / 2A — Metav IndustryLine NOGO thread ring gauge, hardened gauge steel

The Thread ring gauge UNC NOGO, 3/4 x 10 ANSI B1.1 / 2A is a NOGO ring gauge for verifying external UNC threads according to ANSI/ASME standards, intended for workshop and quality‑control inspections.

• Hardened gauge steel construction
• Complies with ANSI/ASME B1.1/B1.2
• Tolerance class 2A for accurate inspection
• NOGO ring for fast thread rejection

Ensure fast, standards-based thread verification for production quality

A NOGO ring gauge such as this provides a straightforward, pass/fail check that integrates seamlessly into incoming inspection and shop‑floor routines. The device is manufactured from hardened gauge steel, which preserves thread geometry under repeated use and reduces wear‑related drift. Conformity with ANSI/ASME B1.1 ensures the thread form and pitch are assessed against the recognised UNC specification, while the 3/4-10 UNC designation clarifies the nominal size and 10 tpi pitch for rapid identification. Using a NOGO ring eliminates subjective judgements during inspection: if the gauge does not enter, the thread meets the maximum material condition defined by the standard. This delivers measurable time savings during routine checks and supports consistent quality documentation in production environments.

Durable design that supports repeatable rejection decisions and traceability

Built to the practical demands of workshop metrology, the gauge’s tolerance class 2A gives inspectors a clear acceptance reference for external threads. The modest mass (0.4 kg) and compact geometry make handling simple, while the hardened material resists deformation, sustaining reliability over many inspection cycles. As a dedicated NOGO ring, the tool is optimised for quick identification of oversize or incomplete threads without the need for additional measurement steps, reducing cycle time in both manual and semi‑automated processes. The ring is suitable for use alongside calipers, optical comparators or recording systems when traceability is required; its plain, standards‑driven function is easy to document in inspection records and quality plans, reinforcing process capability and reducing rework rates.
