The JBO Thread Plug Gauge is a precision inspection tool designed for metric fine threads. With a Go/No-Go design and a left-hand orientation for compatible applications, it lets your team quickly verify threaded holes for correct fit and function, reducing guesswork during assembly.

• Go/No-Go quick checks: A fast pass/fail design for Go and No-Go checks on threaded holes, helping you confirm fit without trial assemblies.
• Hardened steel durability: Built to resist wear, maintain accuracy, and withstand daily use in workshops and production environments.
• Metric fine-thread compatibility (M26 x 1.5, 6H) with left-hand orientation: Specifically sized for metric fine holes and left-handed threads, ensuring precise, reliable inspection for critical components.

This gauge helps you speed up inspection, improve consistency across batches, and reduce rework. By delivering clear go/no-go results for metric fine threads, it supports tighter process control and confident part mating in assemblies that demand precision and reliability.
