JBO Thread Plug Gauge - Metric Fine Go/No-Go - Left Hand - 6G - M27 x 2

The JBO Thread Plug Gauge is a precision tool designed for metric fine threads, enabling fast, reliable checks of threaded holes. This left-hand version (M27 x 2, 6G) uses a clear Go/No-Go design to confirm fit at a glance, making it ideal for automotive, machining, and quality-control environments where exact tolerances matter.

• Go/No-Go quick checks: The Go end threads into the hole smoothly to confirm the size is within tolerance, while the No-Go end should not fit, helping you reject out-of-tolerance holes quickly and reduce guesswork during assembly.
• Left-hand M27 x 2, 6G precision: Specifically designed for left-hand internal threads with size M27 x 2 and 6G tolerance, ensuring accurate, repeatable checks for your exact application.
• Durable hardened steel construction: Built to withstand daily workshop use, the gauge resists wear, maintains accuracy, and provides long service life in busy production environments.

With this gauge in your toolkit, inspections become faster and more reliable, reducing downtime and rework on critical threads. It supports consistent results across batches, simplifies operator training, and helps you verify left-hand M27 x 2 threads with confidence, so you can move projects forward with fewer delays.
