Thread Ring Gauge No. 6 × 40 UNF GO — ANSI B1.1 / 2A by Metav IndustryLine

Thread Ring Gauge No. 6 × 40 UNF GO — ANSI B1.1 / 2A is a GO ring for inspecting external UNF threads in accordance with ANSI/ASME standards

• GO ring for external UNF threads
• No. 6 × 40 UNF, ANSI B1.1
• Hardened gauge steel construction
• Tolerance class 2A for precision

Ensure repeatable pass/fail checking on the shop floor

The GO ring is designed for quick verification of manufactured external threads and reduces inspection time during batch control. With a compact No. 6 × 40 UNF profile and tolerance class 2A, this ring gauge confirms that external threads meet the acceptance limits defined in ANSI B1.1. Inspectors benefit from the unambiguous pass/fail result that helps maintain production throughput and minimises rework, supporting efficient quality routines in small-batch and series production alike.

Robust construction for long-term reliability

Manufactured from hardened gauge steel, the ring offers durable resistance to wear and maintains gauge integrity under frequent use. The right-hand thread form ensures direct compatibility with standard UNF male threads. The solid construction delivers stable contact conditions, which contributes to consistent inspection outcomes and fewer measurement-related uncertainties — an important factor for workshops demanding dependable gauges for daily use.

Standards compliance and traceable identification

Conformity with ANSI/ASME B1.1/B1.2 provides clear interoperability with international thread specifications and facilitates communication across engineering teams and suppliers. The ring is supplied under SKU M315.946.F and carries GTIN 4054469180076, making inventory and traceability straightforward in procurement and inspection records. Use this gauge where a concise, standards-backed verification step is required to secure product conformity before assembly or dispatch.
