The JBO Thread Plug Gauge is a precision Go/No-Go tool designed specifically for metric coarse threads. It helps quality teams, machinists, and maintenance technicians quickly verify threaded holes, ensuring components thread smoothly and fit correctly the first time. With a right-hand orientation and 6H tolerance for M7 x 1 threads, this gauge is built from hardened steel to withstand daily use in busy workshops and deliver consistent results over time.

• Fast Go/No-Go Checks: Two precision ends let you quickly confirm proper thread depth and diameter, speeding up inspections and reducing guesswork.
• Durable Hardened Steel Construction: Hardened steel resists wear, maintaining accuracy through repeated use in demanding shop environments.
• Metric Coarse Thread Ready: Specifically tuned for M7 x 1 coarse threads with 6H tolerance, ensuring reliable engagement with standard components.

In practice, the JBO Thread Plug Gauge speeds threaded-hole inspection, reduces rework, and supports tighter quality control. The dual-ended Go/No-Go design provides clear pass/fail criteria, helping you set up assemblies faster and maintain consistent thread performance across parts and shifts.
