The JBO Thread Ring Gauge (GO) – Metric Fine, Right Hand, 6g, M150 x 2 is a precision inspection tool designed to verify external thread diameters with consistent accuracy. It helps engineering, manufacturing, and quality teams quickly confirm that threaded components meet the required GO standard before assembly or further processing.

Built from hardened steel for durability, this ring gauge is ready for busy workshops, inspection benches, and production lines. Its metric fine sizing, right-hand orientation, and 6g tolerance provide stable, repeatable readings across batches, promoting reliable quality control across multiple parts and suppliers.

• Fast, go/no-go thread verification: Quickly confirm whether the external thread of a component meets the GO limit, reducing inspection time and rework while supporting traceable quality control.
• Durable hardened steel construction: Built to withstand daily wear, resist corrosion, and maintain accuracy even in demanding workshop conditions.
• Metric Fine, right-hand, M150 x 2 specification: Precisely calibrated for metric fine threads with a right-hand thread, delivering consistent measurements across parts and batches for reliable QA records.

Using the JBO Thread Ring Gauge GO as part of your standard inspection process helps you speed up throughput, minimize misfits, and improve overall thread quality. The tool's robust construction and precise sizing reduce downtime, support compliant reporting, and give you confidence that threaded components will assemble correctly in the final product.
