The JBO Thread Ring Gauge GO, Metric Coarse, Right Hand, 6g, M30 x 3.5, is a precision inspection tool used to verify external threads. It lets technicians quickly confirm that threaded components match the exact metric coarse standard, helping ensure proper fit and reliable performance in assemblies.

Built from hardened steel for lasting wear resistance, this gauge is designed for everyday quality checks in manufacturing, engineering labs, and workshop environments. Its straightforward GO measurement supports accurate, consistent results that align with industry standards.

• Precise metric coarse-thread GO gauge: Quick, reliable verification of external thread diameters for M30 x 3.5 right-hand threads, ensuring components meet the exact spec and fit correctly.
• Durable hardened steel construction: Built to withstand daily use, resist wear, and provide long tool life in QA labs and workshop environments.
• Right-hand thread design with 6g tolerance: Optimized for standard metric coarse threads, delivering consistent, repeatable measurements across production runs and audits.

Using this gauge in your inspection workflow helps you confirm thread compatibility early, reducing assembly issues and returns. The durable construction lowers replacement costs and downtime, while the simple GO check speeds up QC, enabling your team to maintain tighter tolerances and higher-quality results with confidence.
