The JBO Thread Ring Gauge (NoGo) in Metric Fine is a precision inspection tool designed to verify external threads on fasteners and machined components. Ideal for quality control labs, machine shops, and production lines, it helps ensure parts conform to the M28 x 2 right-hand thread with a 4h tolerance. This NoGo gauge provides a clear threshold to quickly identify non-conforming parts, supporting consistent, reliable inspections.

• Precise NoGo check for M28 x 2 right-hand threads (4h): Establishes a definitive NoGo limit so inspectors can rapidly determine whether a threaded component meets the specified diameter and thread form, reducing guesswork and speeding up QC decisions.
• Durable hardened steel construction: Built to withstand daily use in busy workshops and production lines, offering excellent wear resistance and long service life even in demanding environments.
• Right-hand metric fine thread compatibility: Specifically matched to fine-thread, external M28 x 2 right-hand threads, ensuring consistent, repeatable checks across parts and minimizing measurement ambiguity.

Using this gauge streamlines your quality workflow by enabling fast, reliable pass/fail decisions, lowering the risk of downstream assembly issues, and reducing inspection downtime. Its robust build and precise sizing give you confidence that every measurement supports accurate manufacturing and compliant, dependable results.
