The JBO Thread Plug Gauge is a precision tool designed to verify metric coarse internal threads, specifically M14 x 2. It’s ideal for engineers, machinists, quality teams, and maintenance personnel who need fast, reliable checks of threaded holes to ensure proper fit and function.

Its go/no-go design delivers immediate pass/fail results, helping inspections stay efficient and accurate. Crafted in a right-hand configuration with a 6H specification, this gauge aligns with standard coarse-thread holes for consistent performance in demanding environments. The hardened steel construction provides enduring durability to withstand rigorous use over time.

• Go/No-Go Quick Check: Quickly determine if a hole meets the M14 x 2 coarse-thread standard with a clear pass/fail result, speeding up quality control and reducing guesswork.
• Rugged Hardened Steel Construction: Built to resist wear and maintain accuracy through heavy use in busy workshops and production lines.
• Right-Hand Metric Coarse Precision: Specifically designed for metric coarse threads (M14 x 2) with a right-hand orientation to ensure correct alignment and reliable measurements.

Using the JBO Thread Plug Gauge helps streamline inspections, improve consistency across parts and batches, and provide confidence that threaded holes will accept properly matched components on assembly. Its durable design supports long-term reliability in professional quality control workflows.
