The JBO Thread Ring Gauge (GO) for Metric Coarse threads is a precision inspection tool designed to verify external threads on components with an M14 x 2 pitch. It's ideal for engineers, machinists, quality teams, and maintenance professionals who need quick, reliable go/no-go checks to confirm parts meet the required lower limit of the specification.

Manufactured from hardened steel, this GO gauge delivers durability in busy shops and inspection rooms. With its right-hand threading and 6e tolerance for metric coarse threads, it provides stable, repeatable measurements that align with industry standards and support consistent part fitment.

• Precisely calibrated for M14 x 2 metric coarse threads: Enables fast, reliable GO-side checks that confirm the thread’s lower limit is met, reducing guesswork and rework in quality control.
• Hardened steel construction for durability: Withstand daily handling and wear, delivering long service life and stable accuracy across many inspections.
• User-friendly, fast QA integration: Simple to use with intuitive alignment and smooth insertion, helping inspectors move through batches quickly without sacrificing precision.

This GO gauge helps you quickly verify external threads meet the lower tolerance for M14 x 2 metric coarse threads, ensuring proper assembly and function. By enabling decisive go/no-go checks, it accelerates quality control, reduces rework, and supports consistent performance across production runs and maintenance tasks.
