The JBO Thread Plug Gauge is a precision inspection tool designed for metric coarse threads. This go/no-go gauge quickly verifies threaded holes to ensure the correct fit in assemblies and housings. With a right-hand orientation and a size specification of M2.3 x 0.4 (6H tolerance), it’s ideal for quality control in manufacturing, machining, and repair environments.

• Go/No-Go design for fast verification: Quickly determine whether a threaded hole meets tolerance, reducing inspection time and preventing misfits in production.
• M2.3 x 0.4 metric coarse thread compatibility: Specifically matched to common metric coarse threads, delivering reliable checks for small-thread applications and consistent fitment across parts.
• Hardened steel construction for lasting durability: Built to withstand frequent use in demanding workshop settings while maintaining accurate, repeatable measurements over time.

Use this plug gauge to streamline quality control workflows: its fast, reliable checks help minimize downtime, improve assembly reliability, and support consistent results across batches. The sturdy construction ensures long-term performance, giving you confidence in every measurement and every fit.
