JBO Thread Ring Gauge (NoGo) - Metric Fine - Right Hand - 4h - M78 x 1.5 is a precision tool used to verify external thread diameters on fasteners and components. Designed for engineers, inspectors, and machinists, it provides quick, reliable go/no-go checks to confirm parts meet the M78 x 1.5 metric fine thread specification and 4h tolerance. Crafted from hardened steel, it delivers long-lasting wear resistance in demanding workshop environments.

• Fast go/no-go verification: Swiftly identify non-conforming parts with a clear pass/fail indication on external threads, reducing inspection time and preventing downstream rework.
• Durable hardened steel construction: Built to endure daily use, this ring gauge resists wear, maintains dimensional stability, and delivers long service life in tough workshop conditions.
• Metric Fine, right-hand M78 x 1.5 with 4h tolerance: Precisely sized for this common external-thread specification, ensuring reliable measurements and consistent qualification of threaded components.

With its precise sizing and rugged construction, this gauge helps standardize thread inspection across jobs, speeds up QA checks, and reduces downtime caused by out-of-spec parts. By clearly indicating non-conforming pieces, it supports reliable assembly, consistent results, and confident decision-making for buyers, engineers, and shop floor technicians alike.
