The JBO Thread Plug Gauge (NoGo) is a precision measuring tool designed to verify metric fine-threaded holes. It’s ideal for machinists, inspectors, and maintenance teams who need fast, reliable pass/fail checks to ensure components meet exact specifications. This NoGo gauge confirms holes do not exceed the specified maximum, helping prevent misfits and rework.

Built as the right-hand version for metric fine threads M76 x 2, it combines precise dimensions with durable materials to deliver consistent results in demanding environments. Crafted from hardened steel, it resists wear and maintains accurate tolerances over many cycles.

• Metric fine thread compatibility: Designed for metric fine-thread holes (M76 x 2) to deliver accurate NoGo checks, ensuring consistent hole quality across parts and batches.
• Durable hardened steel construction: Built to withstand daily use, resisting wear and maintaining accurate dimensions for long service life.
• Right-hand NoGo design for fast checks: Provides quick pass/fail assessment, reducing inspection time and minimizing downtime in production or assembly lines.

With the JBO Thread Plug Gauge, you gain reliable, repeatable measurements that integrate seamlessly into quality control workflows. Quick checks mean shorter inspection times, fewer delays, and less guesswork when assembling parts with metric fine threads. The hardened steel construction ensures the gauge stays within tolerance even after heavy use, giving you confidence in every measurement and reducing the risk of misfits and returns.
