The JBO Thread Ring Gauge (NoGo) — Metric Fine, Left Hand, 6g, M26 x 1 — is a precision inspection tool designed to quickly verify external thread diameters. Ideal for machinists, quality inspectors, and maintenance technicians, it helps confirm that threaded parts meet exact size and fit requirements using the familiar go/no-go method.

Crafted from hardened steel for durability, this gauge is built to withstand busy workshop environments. Its left-hand orientation supports inspection of left-handed threads with consistent, repeatable readings, while the metric fine specification and 6g tolerance ensure reliable performance across multiple checks.

• Precision metric NoGo gauge for M26 x 1 threads: Quickly verify external thread size against the M26 x 1 standard, enabling fast go/no-go decisions and reducing rework.
• Left-hand orientation for left-handed threads: Specifically built to inspect left-handed threaded components with consistent results, preventing misreads in critical assemblies.
• Hardened steel construction with 6g tolerance: Delivers long life in demanding environments and maintains accuracy through heavy use.

With the JBO NoGo gauge in your QA toolkit, you can speed up inspections, reduce rework, and improve first-pass assembly success. The robust construction stays reliable through daily use, helping you make confident decisions about parts before they move into production or maintenance workflows.
