The JBO Thread Ring Gauge (NoGo) – Metric Fine – Right Hand – 4h – M4 x 0.35 is a precision tool designed to verify external thread diameters quickly and reliably. Ideal for quality control teams, machine shops, and engineers, it helps ensure that every threaded component meets the exact M4 x 0.35, 4h specification before it moves to assembly or procurement processes.

• Precise M4 x 0.35 NoGo sizing: Enables fast pass/fail assessment of external threads against the exact metric fine standard, reducing inspection time and helping you identify non-conforming parts at a glance.
• Hardened steel for lasting durability: Built to withstand daily use in demanding environments, providing consistent measurements over many inspections without premature wear.
• Right-hand orientation for consistent measurements: Specifically matched to standard right-handed threads, ensuring reliable, repeatable checks across parts and jobs.

Using this gauge simplifies and accelerates your inspection workflow. It delivers clear, trustworthy results that support tighter quality control, fewer defects, and more efficient production cycles. With robust construction and a straightforward, user-friendly design, the JBO NoGo gauge helps you maintain accuracy, reduce rework, and protect your downstream assembly and quality records.
