The JBO Thread Plug Gauge is a precision tool designed for metric fine threads. It helps machinists, inspectors, and maintenance teams quickly verify threaded holes, ensuring parts fit reliably during assembly and repair. The gauge uses a Go/No-Go design for fast pass/fail checks that keep production moving smoothly.

With right-hand orientation, a M16 x 0.75 thread size, and 4H tolerance, this gauge provides consistent results across common metric holes. The hardened steel body resists wear and stands up to daily workshop use, delivering dependable performance over time.

• Precision Go/No-Go checks: Quickly verify hole readiness with clear go/no-go criteria, enabling fast, reliable decisions and reducing guesswork during inspection.
• Durable hardened steel construction: Built to endure daily use in busy shops, resisting wear and maintaining measurement accuracy for long service life.
• Spec-aligned right-hand gauge (M16 x 0.75, 4H): Ensures consistent results and easy integration into your QC workflow with standard metric threading specifications.

Using the JBO Thread Plug Gauge in your QC workflow helps you reduce inspection time, cut rework, and improve overall thread quality across parts. Its rugged construction means fewer replacements and less downtime, so your team can focus on productive work with confidence.
