The JBO Thread Ring Gauge (GO) - Metric Coarse - Right Hand - 6g - M5 x 0.8 is a precision inspection tool designed to verify external metric coarse threads. It’s ideal for engineers, machinists, quality teams, and maintenance staff who need quick, reliable confirmation that threaded components meet the intended size and fit.

Crafted from hardened steel for durability, this GO gauge resists wear and maintains tight tolerances through repeated use. Its straightforward GO design supports fast, reliable go/no-go checks in standard QA workflows across manufacturing, assembly lines, and service environments.

• Exact M5 x 0.8 coarse-thread sizing: Provides accurate GO measurement for external M5 x 0.8 coarse threads, helping ensure parts meet spec and reduce rework.
• Hardened steel construction: Delivers long tool life and wear resistance in busy shop environments, maintaining accuracy over many cycles.
• Go gauge for fast pass/fail checks: Enables quick, confident inspection decisions on the shop floor, speeding quality checks and reducing downtime.

Using this GO gauge ensures quick, repeatable verification of M5 x 0.8 coarse-thread connections, helping you prevent misfits, cut rework, and keep production on schedule. The hardened steel construction stands up to daily use, preserving accuracy across shifts, while the simple GO-style check makes inspections faster and more confident for operators, inspectors, and quality teams alike.
