The JBO Thread Plug Gauge is a precision instrument designed to verify metric fine threads with ease. Ideal for engineers, machinists, quality-control teams, and dedicated hobbyists, it provides a fast Go/No-Go check to confirm threaded holes meet exact tolerances. With a right-hand orientation and a M17 x 1 fine-thread specification at 6G, this gauge delivers reliable, consistent results in tight-tolerance assemblies.

• Go/No-Go quick verification: Instantly determine pass/fail against tolerance with a simple test, reducing inspection time and avoiding guesswork.
• Durable hardened steel construction: Built to withstand daily workshop use and resist wear, preserving accuracy across many measurements.
• Metric fine-thread precision (M17 x 1, right-hand, 6G): Ensures reliable engagement with mating threads for consistent fits in tight-tolerance assemblies.

By using this gauge, you streamline your inspection process, speed up assembly checks, and improve part-to-part consistency. The robust construction and precise Go/No-Go thresholds help you avoid misfits, reduce rework, and maintain quality across batches, enabling smoother workflows and confident purchasing decisions.
