The JBO Thread Ring Gauge (NoGo) – Metric Coarse, Right-Hand is a precision tool designed to verify external thread diameters on fasteners and threaded components. Specifically sized for M1.6 x 0.35 coarse threads, it enables quick, go/no-go inspections for engineers, machinists, quality teams, and workshop staff.
Ideal for quality control, repairs, and assembly work, this gauge helps ensure consistent fitment and reliable performance across your projects.

• Durable Hardened Steel Construction: Built to withstand daily use in busy workshops, this ring gauge resists wear and maintains accurate dimensions for long service life.
• Fast Go/No-Go Verification: The clear go/no-go design lets you identify non-conforming parts in seconds, reducing inspection time and downtime.
• Specifically Matched to M1.6 x 0.35 Coarse Right-Hand Threads: Precisely sized for the target thread form, enabling reliable, repeatable measurements and confident part acceptance.

With this gauge in your toolkit, inspections become quicker and more consistent, helping you improve workflow, reduce rework, and ensure threaded connections meet your standards for fit and performance across every project.
