The JBO Thread Plug Gauge is a precision tool for verifying metric fine threads in threaded holes. Designed for M25 x 0.5 with a 6H tolerance and a right-hand orientation, it helps ensure components thread together cleanly and consistently in quality control, machining, and assembly tasks.

Built with hardened steel, this gauge resists wear and maintains accurate go/no-go checks through heavy use, delivering reliable performance across demanding workshop environments.

• Go/No-Go efficiency: Quickly determine accept/reject for hole threads, reducing inspection time and preventing misfits.
• Hardened steel construction: Durable, wear-resistant gauge that withstands frequent use in harsh workshop environments.
• Metric fine thread specificity: M25 x 0.5, 6H, Right-Hand: Precisely matched to the target hole class and thread direction for dependable, repeatable checks.

By enabling fast, accurate thread inspection, this plug gauge helps you streamline QC, reduce downtime from misfitted parts, and improve the reliability of assemblies that rely on precise M25 x 0.5 threads. The go/no-go design provides clear pass/fail results, so technicians can work confidently and maintain consistent thread quality across batches.
