The JBO Thread Plug Gauge is a precision tool designed for metric fine thread verification. Specifically, it's built to check M22 x 0.75 holes for 6H tolerance with a Go/No-Go design, making it ideal for quality control, machining, and maintenance applications.

This right-hand plug gauge combines durability with ease of use. The hardened steel body and knurled grip stand up to daily shop use, while the Go/No-Go functionality lets technicians quickly determine if a threaded hole is within tolerance, helping parts mate properly the first time.

• Go/No-Go quick-check design: Quickly verify hole tolerance and thread fit, reducing inspection time and minimizing rework.
• Hardened steel construction: Built to endure repeated use in demanding workshop environments while maintaining measurement accuracy.
• Precise metric size: M22 x 0.75, Right-Hand, 6H: Provides a standard reference size that fits common components and supports reliable, repeatable inspections.

In daily workflows, this gauge accelerates quality checks, improves assembly confidence, and helps sustain consistent thread quality across production runs—delivering faster throughput and fewer surprises at final assembly.
