The JBO Thread Ring Gauge (NoGo) - Metric Coarse - Right Hand - 6h - M30 x 3.5 is a precision external thread gauge designed to verify metric coarse threads with speed and consistency. Built for quality control professionals, engineers, and workshop technicians, it helps ensure threaded components meet exact diameter tolerances before they enter assembly or production lines.

• NoGo quick-pass/fail verification: Provides a clear, quick indication of non-conforming parts by confirming that the minimum-thread condition is within spec, speeding up inspections and reducing rework.
• Durable hardened steel construction: Resists wear and deformation on busy shop floors, maintaining measurement accuracy over many uses and through routine cleaning.
• Metric coarse thread, M30 x 3.5, Right Hand: Precisely calibrated for the M30 x 3.5 coarse thread with a right-hand orientation, ensuring reliable checks and easy integration with standard fasteners.

Using this gauge in your inspection process helps you quickly validate thread integrity, reduces assembly delays, and promotes consistent quality across parts. Its rugged construction and precise sizing mean you can rely on repeatable results, minimize rework, and maintain traceability in your quality system.
