UNF GO Thread Ring Gauge 1 1/4" x 12 (ANSI/ASME B1.1, 2A) — Metav IndustryLine

A UNF GO Thread Ring Gauge 1 1/4" x 12 (2A) designed for rapid verification of external UNF threads to ANSI/ASME tolerances in production and inspection environments

• GO ring gauge for UNF 1¼" x 12 threads
• Manufactured to ANSI/ASME B1.1/B1.2 standards
• Material: hardened gauge steel for durability
• Right-hand thread, tolerance class 2A

Fast, standards-based thread verification for production lines

The gauge enables immediate go/no‑go assessment of external UNF threads, providing a clear pass/fail decision without interpretation. Built to ANSI/ASME B1.1/B1.2 the tool ensures thread interchangeability across suppliers and assemblies, reducing the risk of mismatched fittings. Used as a frontline inspection tool, the GO ring removes ambiguity from routine checks and supports consistent output in batch production.

Durable build that keeps inspection cycles short

Constructed from hardened gauge steel, this ring is made for repeated use in workshop environments where wear resistance matters. The robust material and finished thread profile maintain dimensional stability, lowering the need for frequent replacement and keeping downtime to a minimum. The compact mass (approx. 0.7 kg) and right‑hand configuration simplify handling and storage while offering long service life under normal shop conditions.

Clear technical fit: UNF threads and 12 tpi explained

Designed for UNF 1 1/4" x 12 threads, the gauge checks the external thread against a 12 tpi standard pitch and tolerance class 2A, which is the customary fit for external fasteners requiring controlled clearance. The GO ring confirms whether an external thread falls within the permissible form and dimensions; a successful GO test indicates conformity to the specified limits without measuring every parameter, saving time during routine inspection.

Practical integration into quality workflows

As a simple and reliable inspection instrument, the GO ring is suited to in‑line sampling, receiving inspection and first‑off checks. Its adherence to recognised standards provides traceable confidence in acceptance decisions and supports documentation practices in quality systems. Supply via Metav IndustryLine benefits from a European quality filter and dependable logistics, helping workshops and small manufacturers maintain steady access to essential gauges.

FAQ

What standard does this gauge conform to?
The gauge is manufactured to ANSI/ASME B1.1/B1.2, ensuring compatibility with UNF thread form and dimensional requirements for the specified series.

Which thread size and pitch are covered by this ring?
This GO ring is for UNF 1 1/4" x 12 external threads, checking the standard 12 tpi pitch and external thread form to tolerance class 2A.

How does a GO ring gauge indicate acceptance?
A successful pass with the GO ring confirms the external thread meets the permitted form and dimensions for the specified limits; the tool gives a direct go/no‑go decision without full dimensional measurement.

What material is the ring made from and why is it important?
The ring is made from hardened gauge steel, chosen for wear resistance and dimensional stability to provide consistent inspection results over many cycles.

Can this gauge be used for production sampling and receiving inspection?
Yes, the GO ring from Metav IndustryLine is intended for shop‑floor sampling, incoming goods checks and routine first‑off inspections where fast, standards‑based decisions are required.
