The JBO Thread Ring Gauge GO - Metric Fine, Right Hand, 6g, M12 x 1.25 is a precision tool designed to verify external thread sizes quickly and reliably. It’s ideal for engineers, machinists, quality inspectors, and shop staff who need to confirm that threaded components meet exact specifications in production, assembly, or maintenance tasks.

Crafted from hardened steel for durability, it resists wear in busy environments and maintains its accuracy over many inspections. The GO gauge is specifically tuned for metric fine M12 x 1.25 threads with a 6g tolerance, enabling fast visual verification that a part’s external thread is within spec and will assemble reliably with mating components.

• Metric fine GO gauge for M12 x 1.25: Provides fast, pass/fail checks of external threads, helping inspectors confirm conformance quickly and reduce rework.
• Hardened steel construction: Delivers long-lasting durability and wear resistance, maintaining precise measurements even with frequent use in harsh workshop conditions.
• Right-hand design with 6g tolerance: Ensures compatibility with standard right-hand threads and tight tolerance requirements, delivering consistent results across parts and suppliers.

Using this gauge in your quality control process streamlines inspections, speeds production, and improves confidence that threaded parts will fit correctly in final assemblies. The durable, precise tool minimizes downtime and scrap, supports standardization across teams, and helps you meet quality targets with repeatable, reliable results.
