Go ring gauge UNF, 1 3/8" x 12, ANSI B1.1 — Metav IndustryLine

The Go ring gauge UNF 1 3/8" x 12, tolerance 2A, designed for fast external-thread acceptance testing in production and incoming inspection.

• UNF 1 3/8" x 12, ANSI B1.1
• Hardened gauge steel, wear resistant
• Tolerance class 2A for external threads
• Right-hand thread for standard fasteners

Faster pass/fail decisions to keep production moving

A dedicated Go ring gauge streamlines thread acceptance by providing an immediate pass/fail result for external threads, reducing measurement time compared with full metrological checks. The combination of ANSI B1.1 standard geometry and tolerance class 2A ensures that a correct fit with mating internal threads can be judged reliably; this supports consistent assembly quality and helps to avoid downstream rework. For repetitive quality control tasks, the gauge reduces operator decision time and improves throughput without replacing calibrated measurement equipment.

Standardised compatibility for industrial applications

The gauge matches the UNF thread form and the 1 3/8" x 12 pitch commonly used in heavy‑duty fastenings, making it suitable for maintenance, fabrication and component inspection across automotive and machinery sectors. Conformity to ANSI/ASME B1.1/B1.2 means interchangeability with standard threaded parts and easy integration into existing inspection routines. The right‑hand thread configuration supports verification of typical production items and fastenings without additional adapters.

Durable construction for workshop and shop‑floor use

Manufactured from hardened gauge steel, the ring is built to resist wear from frequent use, maintaining reliable go/no‑go function over a long service life. The compact diameter and balanced mass (~0.7 kg) provide comfortable handling while the robust treatment of the working faces minimises profile distortion. These attributes make the gauge practical for bench inspection and incoming goods checks where repeated engagement with threads is routine.

Simple specification and traceable identification

The tool is supplied with clear identification for traceability: size 1 3/8" x 12, pitch 12 TPI, and the article reference M315.964.F aid inventory management and documentation. Compliance with the ANSI geometry gives technicians an unambiguous reference when recording inspection outcomes, and the straightforward design keeps operator training needs minimal while preserving measurement integrity.

FAQ

What does a Go ring gauge check, and how is it used? A Go ring gauge verifies whether an external thread meets the acceptance limit; the gauge fits the part when the thread is within the 2A tolerance, providing an immediate pass indication for the Go condition.

Is the UNF 1 3/8" x 12 gauge suitable for production inspection? Yes, the UNF 1 3/8" x 12 Go ring gauge is suitable for repetitive production and incoming inspection where quick, standardised pass/fail assessments are required.

How does the tolerance class 2A affect acceptance criteria? Tolerance class 2A defines the external thread limits for a standard Unified thread; the Go ring gauge is manufactured to that class so it confirms if a threaded external part meets the specified fit band.

What are the handling and storage recommendations to preserve the gauge? Store the gauge in a clean, dry environment and avoid impacts; the hardened gauge steel resists wear, but careful handling prolongs the accurate Go/No‑Go function.

Can this gauge be used with non-standard or left‑hand threads? The listed gauge is a right‑hand Go ring for UNF threads; non‑standard or left‑hand threads require a specifically matched gauge.
