The JBO Thread Plug Gauge is a Go/No-Go inspection tool designed specifically for metric coarse threads. It helps machinists, maintenance technicians, quality inspectors, and engineers quickly verify threaded holes for proper fitment and reliable performance.

This left-hand gauge is sized for M14 x 2 coarse threads, built to endure demanding use, and finished to 6H tolerance for consistent accuracy across multiple checks.

• Go/No-Go Design for Fast Hole Verification: Quickly confirm whether a threaded hole meets tolerance by testing with the plug gauge, reducing inspection time and guesswork.
• Hardened Steel Construction for Longevity: Rugged, wear-resistant steel delivers long service life and preserves accuracy in high-volume environments.
• Left-Hand M14x2 Coarse Thread Compatibility: Precisely matched to metric coarse threads with an M14 x 2 size, including left-hand configurations for specialized fittings and assemblies.

Using the JBO Thread Plug Gauge streamlines quality control workflows by providing reliable, repeatable checks that help prevent misfits, reduce rework, and speed up assembly. Its durable construction minimizes downtime and replacement costs, while its compatibility with common coarse-thread applications across industries ensures you can rely on it for consistent results day after day.
