The JBO Thread Plug Gauge is a precision tool designed to verify internal metric coarse threads with confidence. It’s the go-to choice for machinists, inspectors, and assembly teams who need quick, standardized checks of threaded holes.
Sized for M27 x 3 right-hand threads and built to endure regular shop use, this gauge combines a go/no-go design with hardened steel construction for reliable, consistent performance over time.
- Fast Go/No-Go Verification: Quickly confirm whether the threaded hole falls within tolerance, speeding setup and reducing inspection time without sacrificing accuracy.
