The JBO Thread Plug Gauge is a precision inspection tool designed for metric fine threads, specifically sized for M22 x 1.5, with right-hand threading and tolerance class 4H. It helps technicians verify threaded holes during assembly, maintenance, or repair, ensuring parts thread in smoothly and seat properly.

Designed for quick checks, the Go/No-Go arrangement lets you confirm hole size at a glance: the Go end threads in smoothly within tolerance, while the No-Go end should not pass if the hole is out of spec. This speeds setup and reduces guesswork in quality control.

• Go/No-Go Verification: Enables fast, reliable assessment of hole size so you can approve or reject parts in seconds, reducing inspection time and rework.
• Metric Fine Thread Compatibility (M22 x 1.5): Precisely matched to the target thread to ensure consistent mating and prevent mismatches in assemblies.
• Hardened Steel Construction: Built for durability in busy workshops, resistant to wear from repeated use, and able to maintain accuracy over time.

By using this gauge, you streamline threading checks, shorten setup times, and achieve repeatable, dependable results across manufacturing and service environments.
