The JBO Thread Ring Gauge (GO) - Metric Fine - Right Hand - 6h - M12 x 1.25 is a precision Go gauge engineered to verify external thread diameters quickly and reliably. It’s designed for quality teams, machinists, and maintenance technicians who need to confirm that fasteners and threaded components conform to the M12 x 1.25 fine-pitch standard.

Crafted from hardened steel for lasting durability, this gauge maintains its accuracy through heavy daily use. Its true internal thread profile ensures consistent results, while the compact ring design makes insertion and withdrawal smooth for fast pass/fail decisions on the shop floor, in QA labs, or during in-process checks.

• Precise metric GO profile (M12 x 1.25, right-hand, 6h): Delivers reliable pass/fail verification for external threads, enabling you to confirm parts meet exact size and pitch without guesswork.
• Hardened steel construction for durability: Built to withstand daily use in busy environments, resisting wear and corrosion to preserve accuracy and calibration over time.
• Easy, intuitive go/no-go inspection: Ring design and internal threads allow quick alignment and clear results, reducing inspection time and training needs for new staff.

This gauge helps streamline quality control and assembly workflows by providing fast, trustworthy measurements that support consistent results. With the JBO Thread Ring Gauge, you can minimize rework, improve throughput, and maintain confidence that every M12 x 1.25 threaded component meets the required specification.
