The JBO Thread Plug Gauge (GO) – Metric Fine – Right Hand – 6H – M70 x 6 is a precision go gauge designed to validate threaded holes to metric fine standards. Ideal for engineers, quality teams, machinists, and workshop technicians, it helps you quickly determine whether a hole meets the M70 x 6, 6H specification, enabling faster setup and reliable pass/fail decisions.

Constructed from hardened steel with excellent wear resistance, it withstands daily use in demanding environments and maintains accurate measurements over time. The user-friendly GO design makes it easy to identify properly threaded holes during inspections, reducing rework and supporting consistent quality control.

• Go/No-Go verification for metric fine threads: Quickly confirm hole acceptance against M70 x 6, 6H standards, speeding inspections and reducing rework.
• Hardened steel construction: Withstand wear in busy shops and labs, delivering durable, long-lasting measurements and reliable performance.
• Right-hand metric fine thread compatibility (M70 x 6, 6H): Precisely matched to standard right-hand threads, providing repeatable, confident pass/fail results every time.

Used in quality control and manufacturing, this GO gauge helps you verify threaded holes quickly and accurately, reducing inspection time and preventing misfits in assemblies. Its durable construction and precise metric fine sizing provide consistent, repeatable results across batches, boosting confidence in every part.
