The JBO Thread Ring Gauge (GO) - Metric Fine is a precision inspection tool for verifying external threads on fasteners, bolts, and machined components. It is designed for metric fine threads, specifically M30 x 0.75, with a 6e right-hand thread profile, enabling reliable GO checks during quality control and dimensional inspection.

Constructed from high-quality hardened steel, the gauge offers exceptional durability and wear resistance to withstand repeated use in busy workshops, manufacturing lines, and laboratories. Its straightforward design makes it easy to identify properly conforming threaded components, supporting efficient QC workflows and precise engineering decisions.

• Precise GO/No-Go metric verification (M30 x 0.75, 6e, Right Hand): Confirms external thread diameter quickly and accurately, helping you determine whether a component meets the exact standard without guesswork.
• Hardened steel construction for durability: Built to resist wear and maintain accuracy in demanding environments, ensuring long tool life and consistent performance over many inspections.
• User-friendly inspection tool for fast QC: Designed to simplify identification of conforming threads, speeding up checks and reducing downtime in production or quality-control processes.

With the JBO Thread Ring Gauge (GO), you gain a reliable, repeatable method to verify threads, streamline quality control, and help ensure every threaded part meets your specifications. This leads to fewer reworks, faster inspections, and greater confidence across your manufacturing or repair workflows.
