JBO Thread Plug Gauge is a precision tool designed to quickly verify metric fine-threaded holes. It is configured for right-hand M30 x 1 threads with a 6H tolerance, using a Go/No-Go design to provide fast, confident checks for manufacturing, assembly, and quality control tasks.

• Go/No-Go Quick Verification: Quickly determine whether the hole is within tolerance, reducing inspection time and ambiguity in pass/fail decisions.
• Right-Hand Metric Fine Thread Coverage (M30 x 1, 6H): Specifically tuned for metric fine threads, ensuring accurate go/no-go results for right-hand M30 x 1 holes at the 6H tolerance.
• Durable Hardened Steel Construction with Knurled Grip: Built to withstand busy shop environments; the hardened body resists wear and the textured knurling provides a secure, slip-resistant grip for precise alignment.

By providing fast, definitive checks and long-term reliability, this gauge helps you speed up setup, reduce rework, and maintain consistent results across parts and assemblies.
