Thread ring gauge UNEF GO 1 3/8 x 18 – hardened gauge steel, ANSI/ASME B1.1 (Metav IndustryLine)

A Thread ring gauge UNEF GO 1 3/8 x 18 2A for fast, repeatable GO inspection of external UNEF threads in manufacturing and quality control.

• Hardened gauge steel for long lifespan
• UNEF 1 3/8‑18 thread form and 2A tolerance
• Conforms to ANSI/ASME B1.1/B1.2 standards

Reliable construction for production use

The ring is made from hardened gauge steel, which gives high wear resistance and stable dimensional retention during repeated inspections. In practice this means fewer gauge changes and lower lifecycle costs for inspection routines. The go type gauge is designed to verify that external threads meet the maximum material condition specified by the 2A tolerance class, providing a quick accept criterion for throughput-driven production lines.

Standards-based verification to reduce rework

Compliance with ANSI/ASME B1.1/B1.2 guarantees that the thread form and pitch are checked against the recognised UNEF specification. The 1 3/8 × 18 tpi geometry confirms pitch and major diameter simultaneously, enabling clear go/no-go decisions and reducing scrap and rework. This standards-led approach translates into measurable efficiency gains in quality assurance and a documented basis for acceptance in supplier audits.

Practical handling and inspection benefits

Engineered as a GO ring gauge, the tool offers immediate feedback on external thread conformity without elaborate setup. Its compact, robust design supports handheld use at the machine or on the inspection bench while maintaining repeatability under routine conditions. The ring's right‑hand thread and hardened finish make it suitable for shop‑floor environments where traceable, repeatable checks are required as part of incoming goods inspection or final part verification.

FAQ

What is the purpose of this GO ring gauge?
The GO ring gauge checks whether external UNEF threads conform to the maximum material condition; the Thread ring gauge UNEF GO 1 3/8 x 18 2A provides a fast accept criterion for production and incoming inspections.

Which standard does the gauge follow?
The gauge is manufactured to ANSI/ASME B1.1/B1.2, ensuring compatibility with the UNEF thread form and industry inspection practices.

Is the ring suitable for continuous shop‑floor use?
Yes. The hardened gauge steel construction gives the ring resistance to wear and stable performance under frequent handling and routine checks.

Can the gauge verify pitch as well as diameter?
The 1 3/8 × 18 tpi form inherently verifies pitch and major diameter together when used as a GO ring gauge, enabling quick go/no-go decisions.

Who supplies this ring gauge and where can it be ordered?
This item is offered under the Metav IndustryLine range and can be ordered via Metav Werkzeuge; the product listing includes manufacturer details and article references.
