Thread gauge ring UNF GO, 7/16 x 20 — hardened gauge steel, tolerance class 2A

The Thread gauge ring UNF GO, 7/16 x 20 is a GO ring gauge for quick verification of external UNF threads to ANSI/ASME B1.1 tolerances, suited to production control and incoming inspection of turned or threaded parts.

• GO gauge for 7/16 x 20 UNF threads
• Hardened gauge steel for high wear resistance
• Conforms to ANSI/ASME B1.1/B1.2 standards
• Precision class 2A for reliable pass/fail checks

Fast, norm‑compliant pass/fail verification that saves time

A GO ring gauge provides immediate, unambiguous pass/fail information for external threads; this reduces inspection time and prevents non‑conforming parts progressing through the process. The ring is manufactured to ANSI/ASME B1.1/B1.2, ensuring dimensional compatibility with standard UNF 7/16‑20 threads. Using a dedicated GO ring simplifies decision‑making at the machine or inspection bench and supports consistent production flow by eliminating interpretation of provisional measurements. The result is higher throughput and less scrap through early rejection of incorrect threads.

Durable construction for repeated shop‑floor use

Made from hardened gauge steel, the ring resists wear from repeated engagement with threaded components and maintains its form under routine handling. The robust material choice extends service life and reduces the frequency of replacement, which in turn lowers lifecycle costs. The lightweight construction (approx. 0.1 kg) makes the gauge easy to handle during rapid inspections, while the designation as a GO gauge means straightforward operation: part threads that enter the ring freely meet the specified 2A tolerance for external threads. A right‑hand thread configuration is indicated for use with standard right‑hand threaded components.

Integration into quality workflows and traceability

The ring gauge is supplied with clear identification (SKU: M315.953.F, GTIN: 4054469180243) to support inventory control and traceable inspection records. With a defined pitch of 20 tpi and classification for external thread verification, it fits into routine first‑article and production checks as a hands‑on, rapid method of ensuring conformity to standards. The compact tool is particularly effective where repeated, rapid checks are required at the lathe, turning centre or assembly station, complementing dimensional measuring equipment by offering a simple, robust go/no‑go decision step within a documented quality process.

FAQ

What is the primary purpose of this ring gauge?
The ring gauge is a GO gauge designed to verify that external threads meet the dimensional requirements for 7/16‑20 UNF in 2A tolerance, enabling rapid pass/fail checks.

Which standard does the gauge comply with?
This ring gauge is manufactured to ANSI/ASME B1.1/B1.2, ensuring compatibility with UNF thread specifications.

What material is the ring made from and why does it matter?
Manufactured from hardened gauge steel, the ring offers wear resistance and dimensional stability for repeated use in production and inspection.

Can this gauge be used for internal threads?
No; the product is a GO ring gauge specifically for external threads; internal thread checks require corresponding plug gauges.

How is the tool identified for traceability?
Identification is provided via SKU M315.953.F and GTIN 4054469180243 to support inventory and inspection record keeping.
