The JBO Thread Plug Gauge is a Go/No-Go inspection tool designed specifically for metric fine threads. It helps machinists, quality inspectors, and assembly technicians quickly verify threaded holes, ensuring parts assemble with precision.

Built for durability, the right-hand gauge is sized M20 x 0.75 with 6H tolerance and crafted from hardened steel to resist wear in busy workshops.

• Go/No-Go Quick Verification: Enables fast pass/fail checks of threaded holes, reducing inspection time and downtime while ensuring a consistent, correct fit.
• Hardened Steel Construction: Delivers long service life and excellent wear resistance, standing up to repeated use in demanding environments.
• Metric Fine Thread Compatibility (M20 x 0.75, 6H, Right-Hand): Precisely matched size and tolerance for reliable checks with compatible components in production, QC, and assembly workflows.

Using this gauge simplifies setup and quality control: quick go/no-go checks reduce downtime, while the precise size and hardened steel construction deliver reliable, repeatable results across production runs. You can trust it to maintain threading standards and keep assemblies moving smoothly.
