The JBO Thread Ring Gauge (GO) – Metric Fine – Right Hand – 6h – M38 x 1.5 is a precision go/no-go tool designed to verify external thread diameters quickly and reliably. Its ring design makes it easy for inspectors, engineers, and machinists to confirm that a threaded component meets the required maximum diameter and pitch before assembly or fitting.

Crafted from hardened steel for lasting durability, this gauge resists wear in busy workshops and maintains stable accuracy through thousands of inspections. The metric fine specification (M38 x 1.5) and 6h standard align with common industry practices, making it a dependable choice for quality control across machining, manufacturing, automotive, and maintenance environments.

• Precise GO verification for M38 x 1.5 (metric fine): Quickly confirm that external threads meet the intended maximum diameter and pitch, reducing guesswork during fitting and inspection.
• Hardened steel construction for durability: Built to withstand repeated use in busy environments, resisting wear so accuracy stays stable over time.
• Ergonomic, knurled outer edge for secure handling: The textured ring grip enables fast, repeatable testing, even with gloves, supporting efficient workflows.

This gauge helps you streamline quality checks, speed up setup, and improve consistency across parts and operators. With reliable materials and precise dimensions, you can trust measurements to guide decisions, minimize rework, and uphold tight quality standards in production, maintenance, and inspection tasks.
