The JBO Thread Ring Gauge (GO) for Metric Coarse threads is a precision go/no-go gauge designed to verify M9 x 1.25 coarse-thread connections. With a right-hand orientation, it supports fast, reliable checks that quality teams, machinists, inspectors, and fabricators rely on to confirm parts meet exact specifications. Built from hardened steel with a knurled outer surface for a secure grip, it stands up to daily use in busy workshop environments.

• Precise M9 x 1.25 coarse-thread Go gauge: Quickly confirms parts meet the M9 x 1.25 coarse-thread standard, enabling immediate pass/fail decisions and reducing rework.
• Hardened steel construction: Delivers long life and wear resistance, maintaining accuracy even after repeated use in demanding shop conditions.
• Ergonomic knurled ring for easy handling: The textured outer surface provides a secure grip and fast setup in gloves or tight spaces, improving workflow and repeatable results.

By delivering fast, repeatable checks, the JBO Thread Ring Gauge keeps assemblies moving and minimizes delays. Its durable build and exact M9 x 1.25 tolerance enable consistent results across parts and operators, helping teams meet tight schedules and quality targets with confidence.
