Thread Ring Gauge (UNC NOGO) 1 1/4" × 7, ANSI B1.1 / 2A — Metav IndustryLine

The Thread Ring Gauge UNC NOGO, 1 1/4" × 7, ANSI B1.1 / 2A is a go/no-go ring gauge designed for fast verification of external UNC threads in production and quality control environments.

• NOGO ring gauge for UNC 1 1/4" × 7
• Hardened gauge steel construction
• Conforms to ANSI/ASME B1.1/B1.2 standards
• Tolerance class 2A for form and pitch

Reliable thread verification that reduces rework

A dedicated NOGO ring gauge provides an immediate, objective decision at the production line. Manufactured from hardened gauge steel, this go/no-go instrument resists wear and preserves its contact geometry over repeated checks, which translates into stable limits and fewer false rejections. Conformance to ANSI/ASME B1.1 ensures that thread form, pitch and major diameter fall within the internationally recognised UNC specification, enabling consistent interchangeability of fasteners and avoiding costly rework cycles.

Robust design for repeatable measurements

The gauge’s geometry and 2A tolerance class are selected to match standard external thread requirements, offering clear acceptance criteria during rapid inspections. The compact, metal-ring construction concentrates load paths and minimises elastic deformation, so the limiting condition is reproducible from part to part. In practice, this means line operators and inspectors can record dependable pass/fail results without complex fixtures, improving throughput while maintaining documented quality control.

Practical fit into quality systems and traceability

As a simple tool for routine checks, the ring gauge integrates easily into incoming inspection, in-process control and final checks. The physical limit-test method complements dimensional measuring instruments by delivering a quick verification against the specification; this accelerates sorting and prevents non-conforming components reaching assembly. When documented traceability is required, the gauge’s SKU and serial details can be logged in inspection records to support audits and batch release procedures.

FAQ

What size and thread form does this gauge check?
The ring gauge checks external UNC threads at 1 1/4" × 7 tpi and is manufactured to the ANSI/ASME B1.1 specification for UNC form.

Is the gauge suitable for production-line checks?
Yes, the NOGO ring gauge is intended for rapid, repeatable pass/fail inspections in production and inspection areas and is constructed from hardened gauge steel for longevity.

What does tolerance class 2A mean for this gauge?
Tolerance class 2A specifies the acceptable form and pitch envelope for external UNC threads; the gauge is matched to that class so measured threads meet common industrial interchangeability requirements.

Can this ring gauge replace detailed dimensional measurement?
The gauge provides conclusive go/no-go verification and is ideal for routine control; it complements, rather than replaces, detailed measurement when full dimensional documentation or root-cause analysis is required.

How should inspection results be recorded for audits?
Record the gauge SKU (M315.992), inspection date, operator and part details in the quality log; this supports traceability and audit requirements.
