1 1/8" Thread Go/No-Go Ring Gauge UNC 7 TPI, ANSI B1.1/B1.2, Hardened Gauge Steel - Metav IndustryLine

Reliable shop‑floor thread control is achieved by combining a clear No‑Go decision function with ANSI/ASME B1.1 conformity and a hardened gauge steel construction; this prevents oversized UNC 1 1/8" x 7 parts entering assembly and supports consistent quality throughput.

Thread Ring Gauge UNC NOGO 1 1/8" x 7 (ANSI/ASME B1.1) — 2A, hardened gauge steel (Metav IndustryLine)

Thread Ring Gauge UNC NOGO 1 1/8" x 7 2A — a compact, production‑grade No‑Go ring for quick verification of external UNC threads to ANSI/ASME B1.1 tolerances.

• No‑Go check for UNC threads
• Complies with ANSI/ASME B1.1
• Hardened gauge steel for durability
• Tolerance class 2A for dimensional control

Fast, standards‑compliant thread inspection on the shop floor

A dedicated No‑Go ring provides an unequivocal pass/fail result for external UNC threads, speeding up in‑process inspection and reducing subjective interpretation. The supplied ring is sized 1 1/8" x 7 (7 tpi) and manufactured to meet ANSI/ASME B1.1 requirements; as a result, it integrates seamlessly into existing quality control routines that rely on standardised gauging. Using a dedicated ring for the No‑Go condition prevents oversized components reaching subsequent operations, thereby lowering rework rates and protecting assembly integrity.

Built to remain accurate under daily use

The measuring body is made from hardened gauge steel, which resists wear and preserves the critical thread profile over many cycles, ensuring long‑term repeatability. At approximately 0.6 kg the gauge is compact enough for frequent handling yet substantial enough to feel robust in use. The simple, binary inspection method removes interpretation errors common to visual checks, while the material choice reduces thermal and mechanical degradation compared with untreated steels — a direct advantage for production environments where downtime and instrument replacement are cost drivers.

Suited to production control and traceability workflows

A No‑Go ring in tolerance class 2A is designed for the dimensional control of external threads where fit and assembly reliability are essential. The 7 tpi pitch is clearly identified on the gauge and supports quick operator recognition during batch inspection. This ring complements Go gauges and micrometric checks: use the ring for fast sorting and the calibrated measuring equipment for documentary traceability when required. Metav’s distribution and quality filter ensure consistent supply and conformity to standards, which supports robust inspection plans and audit readiness.

FAQ

What is the purpose of a No‑Go ring gauge?
A No‑Go ring gauge rejects external threads that exceed the upper size limit; the supplied Thread Ring Gauge UNC NOGO 1 1/8" x 7 2A ensures oversized parts are identified before assembly, preventing fit issues.

How is this gauge used in a production line?
The gauge is presented to the external thread; a fail (does not go on) indicates compliance with the No‑Go condition. It is intended for rapid sorting and in‑process checks alongside Go gauges and documentary measuring equipment.

What does tolerance class 2A mean for external threads?
Tolerance class 2A defines the dimensional limits for external UNC threads under ANSI/ASME B1.1; it balances manufacturability and fit, making it suitable for general engineering and production applications.

Can the gauge withstand daily handling and repeated use?
Yes; constructed from hardened gauge steel, the ring resists wear and maintains the critical thread form over many inspection cycles, supporting consistent results and reducing replacement frequency.

Is the gauge compatible with quality audits and traceability systems?
The ring serves as a quick verification tool in quality workflows; for formal traceability, pair it with calibrated measuring instruments and documented procedures as required by the quality system.
