The JBO Thread Ring Gauge (GO) – Metric Fine, Right Hand, 6h, M3.5 x 0.35 is a precision tool used to verify external thread diameters and confirm conformity to metric standards. It is designed for engineers, machinists, quality inspectors, buyers, and hobbyists who need reliable, quick checks of threaded parts.

Manufactured from hardened steel, this GO gauge delivers durable performance in busy workshops and inspection labs. The metric fine pitch with right-hand threading ensures you test the correct thread form for small fasteners and common components, helping you make confident pass/fail decisions at a glance.

• Fast go/no-go thread verification: Quickly determine whether a component’s external thread diameter conforms to the M3.5 x 0.35 specification, accelerating inspections and reducing guesswork.
• Durable hardened steel construction: Built to resist wear and maintain accuracy through frequent use in demanding environments, extending tool life and reliability.
• Precise metric fine M3.5 x 0.35, right-hand design: Ensures you’re testing the correct thread form for small fasteners and common right-hand threads, delivering consistent, trustworthy readings.

Using this gauge helps streamline quality control, minimize downtime from misfits, and improve consistency across threaded components. It supports efficient inspections, enhances measurement reliability, and gives you the confidence to proceed with assemblies and production tasks.
