GO thread ring gauge UNF 1" x 12 — GO, 2A (Metav IndustryLine)

A GO thread ring gauge UNF 1" x 12 for fast verification of external UNF threads to ANSI B1.1 standards, designed for workshop and laboratory quality control

• ANSI B1.1 / B1.2 compliant gauge
• Hardened gauge steel construction
• Tolerance class 2A for GO verification
• Right-hand thread configuration

Reliable verification for external UNF threads

The M315.960.F GO thread ring gauge is engineered for straightforward acceptance testing of external threads: conformity to ANSI B1.1/B1.2 and a defined 2A tolerance class ensure that every pass/fail decision rests on established standards. Built as a GO gauge, it confirms that the external thread does not exceed maximum material limits, reducing false rejections and speeding up throughput. This decision-focused approach supports consistent quality control in both workshop and production environments while keeping inspection easy to interpret for operators and inspectors.

Robust construction for long-term use

Made from hardened gauge steel, the ring is specified for durability and dimensional stability under regular handling. The material choice minimises wear at the thread flanks, so the gauge preserves its reference geometry over many cycles; this supports lower lifecycle costs and reduced recalibration frequency. With a nominal mass of 0.6 kg and a thread pitch 12, the design balances handling comfort and sufficient mass for stable seating during inspection, which is particularly relevant where repetitive checks are required.

Practical integration into measurement routines

As a dedicated inspection tool for UNF threads, this ring gauge fits directly into established quality routines: it is intended for use on finished parts to confirm thread acceptability prior to assembly or shipment. The clear GO-only function streamlines decision-making and shortens inspection time compared with multi-function gauges, improving line efficiency. Traceability is supported by the visible GTIN 4054469180434 and the manufacturer SKU M315.960.F, enabling simple recording in quality logs and inventory systems.

Confidence backed by the Metav supply chain

Supplied under the Metav IndustryLine, the gauge benefits from Metav’s role as a quality filter for the European market: consistent stock, transparent order processing and a wide product range for complementary inspection tooling. This provenance provides a reliable procurement route for workshops and inspection labs that require steady availability and documented product specification. The combination of standard conformity, hardened material and clear marking supports both operational reliability and purchasing confidence.
