The JBO Thread Ring Gauge (NoGo) - Metric Coarse, Right Hand, 4h, M1 x 0.25 is a precision inspection tool designed to quickly verify the external thread diameters on metric coarse fasteners and components. It’s ideal for quality control teams, machine shops, and maintenance crews that need fast, reliable checks to confirm parts meet threading specifications.

Crafted from hardened steel, this gauge delivers durable performance in demanding work environments and resists wear through busy production runs. The NoGo profile provides a clear pass/fail indication, helping operators identify non-conforming threads at a glance and reduce rework or assembly delays. Its metric coarse configuration aligns with standard thread sizes, ensuring accurate, repeatable measurements across batches.

• Go/No-Go external thread verification: Quickly assess whether a part's external thread diameter passes the defined limits, enabling fast, repeatable screening and reducing rework.
• Durable hardened steel construction: Built to endure daily use in busy workshops, with excellent wear resistance that preserves accuracy over time.
• Right-hand metric coarse compatibility (M1 x 0.25): Specifically tuned for common metric coarse threads with right‑hand orientation, providing reliable measurements and smoother workflow in typical assembly environments.

Using the JBO NoGo Ring Gauge for metric coarse threads streamlines inspection workflows by delivering clear, objective results and reducing guesswork. The robust construction lowers replacement costs and minimizes downtime, while the Go/No-Go approach supports consistent quality across batches and ensures metric coarse threaded connections meet required standards for reliable fitment and performance.
