Thread ring gauge UNF GO 1 1/2" x 12, ANSI B1.1 – Metav IndustryLine

A Thread ring gauge UNF GO 1 1/2" x 12 for quick verification of external UNF threads in production and inspection workflows

• UNF GO gauge for 1 1/2" x 12 threads
• Conforms to ANSI/ASME B1.1/B1.2 standard
• Hardened gauge steel construction
• Tolerance class 2A for external threads

Fast and reliable thread verification for production lines

A dedicated GO thread ring gauge speeds up acceptance checks on turned and machined shafts by providing a single, unequivocal pass criterion. Sized for 1 1/2" x 12 UNF threads with a 12 tpi pitch and 2A tolerance class, this gauge is designed to check external UNF threads against the ANSI/ASME B1.1 profile quickly and repeatedly. Using a GO-only ring eliminates ambiguity during rapid throughput inspections: a fit confirms the thread meets minimum material and form requirements, which supports faster in-process decisions and reduces the time spent at the inspection stage.

Built for durability and consistent results in the workshop

Constructed from hardened gauge steel, the ring offers high wear resistance and dimensional stability, which helps maintain repeatability across many cycles. The right-hand thread orientation matches standard production threads and the robust build minimises deformation under normal handling, so the ring remains a reliable pass gauge over extended use. The compact, single-gauge format simplifies storage and handling on the shop floor while delivering the mechanical resilience expected in machining and quality-control environments.

Seamless integration into quality control routines

Conformity to ANSI/ASME B1.1/B1.2 makes the ring gauge a straightforward choice for firms aligning with international thread standards. The gauge supports standardised inspection procedures, shortens cycle times for thread verification and contributes to reduced scrap and rework by detecting out-of-spec parts early. Its clear pass/fail logic complements digital data collection or manual logging in existing workflows, enhancing traceability and process discipline without complex setup.

FAQ

What is the primary use of this ring gauge?
The Thread ring gauge UNF GO 1 1/2" x 12 is used to verify acceptance of external UNF threads to the ANSI/ASME B1.1 profile; a pass indicates the thread meets minimum form and size criteria.

Does this gauge check against international standards?
Yes — the ring is manufactured to conform with ANSI/ASME B1.1/B1.2, ensuring compatibility with common UNF thread specifications.

Is this a GO or NO-GO gauge?
This item is a GO ring gauge only; it confirms whether a shaft or external thread is within the lower and nominal tolerances required for acceptance.

What material is the gauge made from and how durable is it?
The ring is made from hardened gauge steel, offering enhanced wear resistance and long-term dimensional stability suitable for regular shop-floor use.

Can this gauge be used for left-hand threads?
No — this ring is produced with a right-hand thread; left-hand threads require a dedicated left-hand ring.
