Thread ring gauge UNF GO No. 5 x 44 – Ring gauge (ANSI/ASME B1.1, 2A) by Metav IndustryLine

The Thread ring gauge UNF GO No. 5 x 44 is a precision GO gauge designed for verification of external UNF No. 5 threads at 44 TPI, suitable for workshop and inspection environments and built to ANSI/ASME B1.1 requirements

• GO ring gauge No. 5 UNF
• ANSI/ASME B1.1 compliant
• Hardened gauge steel construction
• 44 TPI for fine UNF threads

Consistent pass/fail assessment with industry standards

A dedicated GO ring gauge provides a straightforward, objective check of external thread form. The GO gauge confirms that a thread lies within the allowable maximum material condition defined by ANSI/ASME B1.1, while the 2A tolerance denotes the intended fit class for external threads. In routine quality control this reduces ambiguity: an item that passes the GO gauge meets the defined thread size envelope for acceptance. The simplicity of the GO check shortens inspection cycles and supports repeatable results across operators.

Robust build for repeated workshop use

Manufactured from hardened gauge steel, the ring is engineered for dimensional stability and wear resistance during frequent use. The hardened material maintains contact geometry under mechanical loading, which preserves the gauge form and extends service life in busy production settings. The device’s right‑hand thread orientation suits standard UNF thread direction, and the compact mass facilitates handling and storage without unnecessary bulk. The construction choices reduce maintenance needs and help sustain measurement confidence over long production runs.

Practical integration into quality processes

A precision ring such as this simplifies go/no‑go decisions at incoming inspection, final assembly checks and in‑process control. Its defined thread pitch of 44 TPI makes it a precise tool for fine UNF threads commonly found in small fasteners and threaded components. Traceable identification via the supplied SKU and GTIN supports inventory management and audit trails, while the clear normative reference streamlines documentation for quality systems. Using a purpose‑made gauge speeds throughput and creates a verifiable basis for acceptance that complements dimensional measurement instruments.

FAQ

What does the GO designation mean for this ring gauge?
The GO designation indicates the ring verifies that an external thread falls within the maximum material limits set by the standard; the Thread ring gauge UNF GO No. 5 x 44 confirms acceptability according to ANSI/ASME B1.1.

Which standard governs the dimensions of this gauge?
This ring gauge is manufactured to the dimensional requirements of ANSI/ASME B1.1, ensuring compatibility with UNF thread definitions and acceptance criteria.

Is the gauge suitable for fine UNF threads at 44 TPI?
Yes, the gauge is specifically produced for No. 5 UNF threads with a 44 TPI pitch and is intended for verification of such fine‑pitch external threads.

What material is used for the ring and why?
The gauge is made from hardened gauge steel to maintain form under repetitive contact, offering wear resistance and dimensional stability during inspection cycles.

How should this ring gauge be used in a quality workflow?
Use the ring as a GO check during incoming inspection, in‑process control or final acceptance; passing the GO ring confirms the external thread meets the specified acceptance envelope for the relevant batch or component.
