The JBO Thread Ring Gauge (GO) for Metric Fine threads is a precision go/no-go tool designed to verify external thread diameters. Specifically built for M24 x 1.25 metric fine threads and right-hand orientation, it helps quality teams, machinists, and inspectors confirm that parts meet the correct standard before assembly or production continues. It weighs about 6 g, making it easy to handle in busy workshops.

Crafted from hardened steel for durability, this GO gauge resists wear in repeated use and challenging work environments, delivering consistent performance over time. Its user-friendly design makes it easy to identify which threaded components conform to the specification, speeding up inspections without sacrificing accuracy.

• Precise GO thread verification: Quickly determines if external threads match the M24 x 1.25 metric fine standard, enabling reliable pass/fail decisions without guesswork.
• Durable hardened steel construction: Built to last under daily use, offering wear resistance and long service life in demanding environments.
• Right-hand orientation for consistent checks: Aligns with standard threading conventions to ensure uniform results across operators and tools.

Used in quality control workflows, this gauge helps reduce inspection time, minimizes rework, and supports reliable assembly outcomes. With its precise dimensions and rugged construction, it enables repeatable measurements across shifts and teams, boosting confidence in every threaded component.
