Thread Go Ring UNEF GO, 7/16 x 28 ANSI B1.1 / 2A — Thread verification ring (hardened gauge steel) from Metav IndustryLine

The Thread Go Ring UNEF GO, 7/16 x 28 ANSI B1.1 / 2A is a hardened gauge-steel verification ring for inspection of external UNEF threads, designed for production and quality-control environments to check conformity with ANSI/ASME standards.

• UNEF 7/16‑28, ANSI/ASME B1.1 compliance
• Hardened gauge steel construction
• Tolerance class 2A Go verification
• Right-hand thread geometry

Consistent thread verification for repeatable results

A Go ring in hardened gauge steel offers straightforward, fast verification of external thread form and major diameter; the UNEF 7/16‑28 dimension refers to a 7/16‑inch nominal diameter with 28 threads per inch (tpi). Using a Go ring simplifies go/no‑go decisions at the bench: the ring must assemble freely onto a correctly produced external thread, making the inspection task objective and rapid. Compliance with ANSI/ASME B1.1 ensures that the ring measures against recognised dimensional tolerances, which supports traceable acceptance criteria on the shop floor and during incoming inspection.

Durable design that supports production rhythms

Manufactured from hardened gauge steel, the verification ring resists wear and maintains its form under frequent use, extending service life and reducing replacement intervals. The tolerance class 2A Go condition provides a defined acceptance limit for external threads, suitable for many machining and assembly applications where fit and interchangeability are required. The right‑hand thread geometry matches standard production threads and keeps handling intuitive for operators, improving cycle times during batch inspection and assembly checks.

Practical handling and inspection benefits

The ring’s compact format and low mass make it easy to locate at inspection stations and incorporate into routine quality checks without additional fixtures. As a dedicated Go gauge, it supports efficient quality workflows by eliminating subjective measurement interpretation: pass/fail becomes tactile and immediate. For traceability and procurement, the gauge is identified by its SKU and GTIN for inventory control and reordering, making it simple to keep inspection tooling consistent across multiple workstations.

FAQ

What is the purpose of a Go ring for UNEF threads? A Go ring is used to verify that an external thread meets the minimum acceptance dimensions; the Thread Go Ring UNEF GO, 7/16 x 28 ANSI B1.1 / 2A confirms that a part will assemble to the specified 7/16‑28 UNEF form.

Which standard does this gauge reference? This verification ring is made to ANSI/ASME B1.1/B1.2 specifications, allowing inspections to be performed against widely recognised US thread standards.

What does tolerance class 2A indicate for external threads? Tolerance class 2A defines the acceptance limits for external threads; using the Go condition of this ring ensures manufactured threads fall within the permitted major‑diameter and form limits for general engineering fits.

Is the ring suitable for high‑volume shop use? Yes — constructed from hardened gauge steel, the ring is designed for repeated assembly checks in production environments where durability and repeatability are required.

How is the thread pitch represented for this gauge? The gauge dimension 7/16 x 28 denotes a 7/16‑inch nominal diameter with 28 threads per inch (tpi), the standard pitch for the UNEF size listed.
