The JBO Thread Plug Gauge - Metric Fine Go/No-Go (Right Hand, 6G, M12 x 1) is a precision inspection tool designed to verify threaded holes with metric fine threads. It’s ideal for engineers, machinists, inspectors, and workshop teams who need fast, reliable hole validation without guesswork.

Crafted from hardened steel, this gauge delivers durable, long-lasting performance in everyday shop use, resisting wear and maintaining accuracy over time.

• Fast Go/No-Go verification: Quickly determine if a threaded hole is within spec with simple pass/fail checks, reducing inspection time and rework.
• Metric fine thread specificity (M12 x 1, right-hand, 6G): Precisely matched to the target size and class to ensure reliable, repeatable hole validation in production.
• Hardened steel for enduring durability: Built to withstand daily use, resisting wear and maintaining accuracy for long tool life.

Using this gauge streamlines quality control, speeds up assembly, and improves consistency across batches. Its robust design provides confidence in thread validation, helping you minimize downtime and achieve reliable, repeatable results in every project.
