The JBO Thread Plug Gauge is a precision Go/No-Go tool designed for metric fine-thread holes. This right-hand gauge is sized for M33 x 3 with a 6H tolerance, enabling fast and reliable checks during machining, assembly, and quality control. Its knurled body provides a secure grip, while the compact design makes alignment quick even in tight spaces. Built for durability, the gauge uses hardened steel to resist wear and maintain accuracy over thousands of checks.

• Fast Go/No-Go verification: Quickly confirm whether a threaded hole meets spec with distinct Go and No-Go limits, reducing guesswork and rework during setup and inspection.
• Rugged hardened steel construction: Designed for busy workshops, it resists wear and maintains accuracy over many cycles of use.
• Metric fine-thread compatibility (M33 x 3, 6H, Right Hand): Precisely matched to standard metric fine threads, ensuring reliable checks for correct fit and easy integration into your quality workflow.

Using the JBO Thread Plug Gauge streamlines quality control and setup, helping you verify hole acceptance early and avoid assembly delays. Its durable build and clear Go/No-Go indicators support consistent results across production runs, giving you confidence in every measurement and a smoother, more efficient workflow.
