The JBO Thread Ring Gauge (NoGo) is a precision tool designed to verify external metric threads. It is ideal for quality control professionals, machinists, and assembly technicians who work with metric fine threads, especially M38 x 1.5 right-hand configurations. This NoGo gauge helps confirm that a threaded part does not exceed the upper tolerance, enabling quick, reliable pass/fail inspections.

Manufactured from hardened steel for durability, the gauge provides long-lasting performance in busy workshops. Its metric-fine size, right-hand orientation, and 6g tolerance ensure compatibility with standard inspection routines and help you maintain consistent quality across parts.

• Exact Metric Fine Size for M38 x 1.5 Right-Hand Threads (6g): The gauge is calibrated for the M38 x 1.5 metric fine thread with a 6g tolerance, enabling quick, definitive NoGo checks to ensure the thread does not exceed the maximum allowed diameter.
• Hardened Steel Construction for Long Life: Built from high-quality hardened steel to resist wear, corrosion, and rough handling in busy shops, providing durable, repeatable performance over many inspections.
• Ergonomic, Knurled Edge for Easy Handling: The textured outer rim offers a secure grip and fast setup, helping inspectors work efficiently even when wearing gloves or in tight workspaces.

With the JBO NoGo Thread Ring Gauge, you gain a reliable, fast, and repeatable method to confirm that external threads meet specification. It helps reduce rework, speeds up QA cycles, and supports consistent results across batches, making it a dependable addition to any machining, manufacturing, or assembly operation.
