The JBO Thread Plug Gauge is a precision instrument designed for metric fine threads. It enables Go/No-Go testing of threaded holes to ensure components screw together cleanly and reliably.

Built for machinists, inspectors, and assembly professionals, this gauge confirms M10 x 0.75 thread holes to the 6H tolerance with a Right Hand orientation, delivering fast, objective pass/fail results.

• Go/No-Go quick verification: Provides fast, objective checks to confirm hole readiness and prevent misfits during assembly.
• Hardened steel construction: Resists wear and maintains accuracy through repeated use, reducing replacement costs and downtime.
• Metric fine thread compatibility (M10 x 0.75, 6H, Right Hand): Engineered specifically for metric fine-thread holes to ensure testing matches the exact thread standard used in your parts.

The JBO Thread Plug Gauge delivers a reliable, repeatable method for hole threading checks, helping you streamline inspections, improve consistency across parts, and confidently verify fits in busy workshops, QC labs, or engineering benches.
