UNF GO Thread Ring Gauge No. 0 × 80, ANSI/ASME B1.1 – Metav IndustryLine

A UNF GO thread ring gauge No. 0 × 80 designed for rapid verification of external unified fine (UNF) threads, manufactured to ANSI/ASME B1.1 tolerances for workshop and inspection use.

• Hardened gauge steel construction
• ANSI/ASME B1.1/B1.2 compliance
• Right‑hand thread, class 2A fit

Reliable pass/fail verification for production control

The primary role of this GO ring gauge is to provide an unambiguous pass/fail check during manufacturing and incoming inspection. Manufactured from hardened gauge steel, the gauge offers high wear resistance and maintains dimensional integrity over repeated cycles, which reduces rejects caused by gauge wear. Conformance with ANSI/ASME B1.1 ensures the ring checks the mating external thread to the specified nominal form and pitch (No. 0 × 80), delivering reproducible acceptance criteria for assembly or shipment.

Consistent fit assessment with a class 2A profile

Designed for the 2A tolerance class, the gauge reflects the intended maximum‑material condition for external threads, enabling efficient verification of mating parts without time‑consuming measurements. The right‑hand thread orientation and the 80 threads‑per‑inch specification match standard UNF geometry; the result is a simple, repeatable inspection step that integrates into production lines, quality stations and gauge blocks. This approach reduces measurement ambiguity and supports fast decision making on shop floors.

Durable design for workshop and inspection environments

Heat treatment and precise finishing deliver a robust tool that resists deformation under normal handling. At approximately 0.1 kg and with a compact No. 0 size, the ring is easy to handle and store while resisting surface damage that can compromise accuracy. The combination of material choice and finishing reduces maintenance intervals and supports a steady throughput in small‑part production or detailed batch inspection tasks.

Traceability and standards conformity for quality systems

Supplied to meet established thread standards, the gauge supports documented inspection regimes and audit trails. Its alignment with recognised norms simplifies inclusion in quality plans and calibration schedules. For customers seeking reliable gauges from an experienced supplier, the Metav IndustryLine offering is positioned as a workshop‑ready, standards‑compliant choice that complements broader metrology toolkits.

FAQ

What is the purpose of a GO ring gauge for UNF threads?
A GO ring gauge provides a clear pass/fail check for external UNF threads; the part must enter the UNF GO thread ring gauge No. 0 × 80 to be accepted against the specified form and pitch.

Is the gauge suitable for routine production inspection?
Yes, the hardened construction and ANSI/ASME conformity make the Metav IndustryLine GO ring gauge appropriate for regular workshop and incoming inspection tasks.

What does the 2A tolerance class indicate?
The 2A designation refers to the external thread tolerance band used for general engineering; the No. 0 × 80 GO ring gauge corresponds to that profile for consistent mating with 2B internal threads.

How should the gauge be stored to preserve accuracy?
Store the gauge in a clean, dry environment and keep it protected from knocks; the hardened surface resists wear but correct handling extends service life.

Can this gauge be used on left‑hand threads?
No, this item is manufactured as a right‑hand thread ring gauge and is intended for standard right‑hand UNF thread forms.
