Designed for precision‑focused inspection of external threads, the JBO Thread Ring Gauge (GO) — Metric Fine (M17 x 1, right‑hand, 4H) helps technicians quickly verify that components conform to exact standards. Built for demanding environments, its hardened steel body resists wear and maintains accuracy over time.

• High-precision metric fine Go gauge: Delivers reliable GO checks for metric fine threads, enabling fast, at‑a‑glance conformance verification during setup, inspection, and quality control.
• Hardened steel construction for durability: Withstands daily use and repeated handling, resisting wear to maintain long‑lasting accuracy in busy workshops.
• Right‑hand 4H compatibility for M17 x 1 threads: Specifically sized for common right‑hand metric fine threads with 4H tolerance, ensuring consistent pass/fail results and fewer rechecks.

This gauge streamlines quality control by providing quick, repeatable thread verification, reducing inspection time and rework. Its durable construction and precise GO design help maintain consistent results across batches, supporting reliable assembly and precise engineering in manufacturing, automotive, and industrial maintenance contexts.
