1 1/8" Thread Ring Gauge UNC 7 TPI Go ANSI B1.1 / 2A - Metav IndustryLine

Take advantage of the combination of ANSI/ASME B1.1 compliance, hardened gauge steel construction and a clear tolerance class 2A specification for fast, reliable thread inspection; order the gauge directly via Metav Werkzeuge or consult our specialists for application advice.

Thread ring gauge UNC GO, 1 1/8" x 7, ANSI/ASME B1.1, 2A — Metav IndustryLine GO ring gauge

The Thread ring gauge UNC GO, 1 1/8" x 7, 2A is a GO ring for rapid verification of external UNC threads to ANSI/ASME B1.1 tolerances, intended for production and incoming inspection in machine shops and quality departments.

• Hardened gauge steel construction
• ANSI/ASME B1.1 compliant
• Tolerance class 2A for GO verification
• Size 1 1/8" x 7 UNC thread

Quick, standards-based thread verification for production control

A GO ring gauge provides an immediate pass result when an external thread meets the required form; this specimen is manufactured to ANSI/ASME B1.1 and marked as tolerance class 2A, so inspection decisions are based on recognised industry references. The use of a GO-only ring speeds up sorting and first-article checks, reducing cycle time at the inspection desk and enabling consistent in-process control. Because the gauge checks basic form and pitch compliance, it is particularly useful where fast, repeatable Go/No‑Go checks are needed rather than full dimensional analysis.

Durable construction that preserves accuracy over many checks

Made from hardened gauge steel, the ring offers wear resistance and dimensional stability under normal workshop conditions. Hardened tool steel provides a hard contact surface that resists abrasion from repeated engagement with threaded parts, which helps maintain repeatability during high-volume sampling. The compact, single-piece design minimises handling errors and ensures the functional face remains true; this lowers the risk of false rejects and supports reliable quality control routines across production batches.

Practical integration into quality workflows and traceability

This ring is sized for a 1 1/8" x 7 UNC pitch and labelled for straightforward identification in a standards-compliant inspection environment. The gauge is suitable for shop-floor verification, incoming inspection and use in assembly jigs where a quick GO check is sufficient to confirm acceptability. The product is supplied with a GTIN for inventory control and is listed under Metav IndustryLine for procurement traceability, helping quality managers keep audit trails tidy and stock records accurate.

FAQ

What is the primary purpose of this ring gauge?
The ring gauge is designed as a GO check for external UNC threads; the Thread ring gauge UNC GO, 1 1/8" x 7, 2A confirms whether a threaded part meets the specified form and pitch according to ANSI/ASME B1.1

Which materials can be checked with this gauge?
Any manufactured external thread of compatible size and pitch can be checked; the gauge itself is made from hardened gauge steel to withstand engagement with common workshop materials without rapid wear.

How does tolerance class 2A affect inspection?
Tolerance class 2A specifies the allowed geometric limits for an external UNC thread; using this GO ring gauge gives a practical and standards-linked pass criterion suitable for general production and assembly checks.

How is the product identified for stock and traceability?
The gauge is listed under Metav IndustryLine and carries GTIN 4054469180441 and SKU M315.961 for straightforward inventory control.
