The JBO Thread Plug Gauge is a precision tool designed to verify metric fine internal threads with confidence. Built for engineers, machinists, quality inspectors, and workshop technicians, it delivers fast, reliable checks for right-hand M35 x 0.5 threads (6H) to ensure fit and consistency across assemblies. With a Go/No-Go design, you can determine acceptance at a glance, speeding up inspections in busy production environments.

• Go/No-Go quick checks: Quickly determine acceptance in one pass, reducing inspection time and preventing misfit parts in assembly.
• Right-hand metric fine thread, M35 x 0.5 (6H): Precisely sized for common metric fine-thread holes, delivering consistent, repeatable results across parts and batches.
• Hardened steel construction with knurled grip: Built to withstand daily shop use, resist wear, and provide secure handling for precise alignment during checks.

By delivering quick, dependable thread verification, the JBO Thread Plug Gauge helps speed up QC cycles, reduce rework, and improve threading consistency across your parts. The durable, hardened steel body and clear Go/No-Go criteria give you confidence to source, inspect, and assemble threaded components—the result is fewer delays, improved first-time fit, and better overall performance in your manufacturing or workshop workflow.
