The JBO Thread Plug Gauge is a precision tool designed for metric fine threads, helping you verify that internal holes meet the M19 x 1.5 specification. With a Go/No-Go design and right-hand thread compatibility, it provides fast, confident checks that speed up setup and quality control in machining and assembly environments.

• Go/No-Go Design for Quick Checks: Instantly confirm whether the M19 x 1.5 internal threads meet tolerance, enabling fast, decisive pass/fail inspections and reducing hold-ups in production.
• Hardened Steel for Long-Lasting Durability: Built to withstand daily use, resist wear, and maintain accuracy over thousands of insertions and inspections.
• Metric Fine Thread Precision (Right-Hand, 6H): Precisely sized for metric fine threads with 6H tolerance, delivering consistent, repeatable results across multiple jobs.

Using this gauge helps you verify thread holes with confidence, shorten setup times, and reduce rework in quality control and assembly workflows. The robust construction and accurate sizing support reliable mating of components, improving overall production efficiency and downstream performance.
