The JBO Thread Plug Gauge (NoGo) – Metric Fine, Left Hand, M48 x 2, 6H is a precision tool designed to verify metric fine threaded holes. It’s built for engineers, machinists, inspectors, and quality teams who need quick, reliable NoGo checks on left-hand threads.

• Metric Fine precision for accurate hole checks: Precisely machined for metric fine threads (M48 x 2) with 6H tolerance, enabling repeatable NoGo verification of threaded holes.
• Left-hand thread design for correct testing: Specifically built to test left-handed threads, reducing misreadings and ensuring you verify the actual production geometry.
• Hardened steel construction for durability: Made from hardened steel, delivering wear resistance and long service life in busy shops, with stable measurements over time.

Used as part of a robust inspection routine, this NoGo gauge helps you quickly confirm thread acceptance, streamline quality checks, and maintain consistent results across parts and shifts. Its durable construction supports reliable performance in demanding environments, giving you confidence in every measurement.
