The JBO Thread Plug Gauge (NoGo) - Metric Fine is a precision inspection tool designed to verify internal metric fine threads. It’s an essential instrument for quality control teams, machinists, and maintenance professionals who need quick, reliable checks of threaded holes.

Made from hardened steel for durability, this gauge is built to withstand busy shop environments and deliver consistent results. The Right Hand orientation and 6H tolerance are specified for M62 x 3 metric fine threads, ensuring accurate Go/NoGo assessments every time.

• Go/NoGo verification for metric fine threads: Quickly confirm whether a hole meets the designated M62 x 3 size, delivering fast, unambiguous pass/fail results that speed up inspection and reduce rework.
• Hardened steel construction for longevity: Resists wear and maintains precise dimensions through frequent use, minimizing replacement costs and downtime.
• Right-hand orientation with 6H tolerance: Precisely matched to metric fine thread standards, providing consistent measurements across tools and parts for reliable quality control.

With the JBO Metric Fine NoGo plug gauge in your toolkit, you can streamline inspection workflows, prevent misfits before assembly, and ensure threaded components meet strict specifications. Its durable construction and precise tolerances translate to fewer rejects, faster setup, and greater confidence in every measurement—ideal for production lines, contract manufacturing, and repair operations alike.
