Thread Ring Gauge UNC GO No. 1 x 64 — Go Ring Gauge by Metav IndustryLine

A Thread Ring Gauge UNC GO No. 1 x 64 for quick, repeatable acceptance testing of external UNC threads to ANSI/ASME B1.1 tolerances.

• Hardened gauge steel construction
• Conforms to ANSI/ASME B1.1 2A
• Precision Go ring for UNC No. 1 x 64
• Compact, easy-to-store format

Fast, reliable pass/fail control that keeps production moving

A compact Go ring gauge provides an immediate pass/fail result for externally threaded parts, reducing inspection time compared with full metrological measurement. Manufactured to ANSI/ASME B1.1/B1.2, this ring is specified for the common UNC thread form and the 2A tolerance class, which ensures interchangeability across suppliers and machines. The result is a measurable reduction in rework and scrap rates, plus predictable acceptance criteria that integrate cleanly into statistical process control routines.

Robust materials and machining for long service life

Made from hardened gauge steel, the ring is designed for wear resistance under repetitive use. Heat treatment and precision finishing preserve thread profiles and minimise wear‑related drift, so inspection intervals can be scheduled rather than reactive. The construction supports stable inspection behaviour even in workshop environments, making the tool a cost‑effective component of a long‑term quality assurance strategy.

Simple to use and integrate within inspection workflows

The ring’s compact size and low weight support rapid handling on the shop floor and easy storage in inspection kits. As a GO gauge, it is intended to engage the external thread under controlled fit; a correct part should screw on without play that would indicate undersize. The device is suitable for fast inline checks at incoming inspection, assembly stations or final inspection, enabling technicians to make consistent decisions with minimal training. Traceability is supported through the clear article designation M315.941 and GTIN for inventory management.

FAQ

What does "Go" mean for this ring gauge?
A Go ring gauge permits a correctly produced external thread to pass; the supplied Thread Ring Gauge UNC GO No. 1 x 64 confirms that the thread form and major diameter meet the acceptance limits for a Go condition.

Is this gauge suitable for production line checks?
Yes. The Metav IndustryLine Go ring gauge (SKU M315.941) is intended for fast, repeatable pass/fail checks at incoming inspection or on the production line due to its compact format and robust construction.

Which standard does the gauge comply with?
The ring is manufactured to ANSI/ASME B1.1/B1.2, ensuring compatibility with UNC thread specifications and the specified 2A tolerance class.

How does the material affect performance?
Manufactured from hardened gauge steel, the gauge resists wear and preserves the thread profile, extending service life and supporting consistent inspection results.

Can this gauge be used to check internal threads?
No. This product is a Go ring gauge designed exclusively for verifying external UNC threads; internal threads require the corresponding plug gauge.
