The JBO Thread Ring Gauge (NoGo) in Metric Fine is a precision tool for verifying external threads on fasteners and threaded components. Sized for M16 x 1 with a 6g tolerance and right-hand orientation, it helps inspectors confirm that parts meet the required thread form and diameter.

The gauge’s hardened steel body and knurled edge provide durable, long-lasting performance in busy workshops, labs, and production lines. Its NoGo design offers clear pass/fail feedback, making it easy to identify non-conforming parts at a glance and keep your quality checks moving smoothly.

• Accurate NoGo verification for metric fine threads: Quickly check M16 x 1 threads (6g) to ensure compliant outer diameter and thread form, enabling reliable disposition of parts.
• Hardened steel construction for long service life: Built to resist wear and maintain dimensional integrity through repeated use in demanding environments.
• Easy identification of non-conforming parts: Simple, intuitive indication helps you make fast, confident go/no-go decisions and reduce inspection time.

Using the JBO NoGo gauge streamlines threaded-part inspections, reduces rework, and supports consistent results across batches. Its reliable accuracy and rugged design give teams the confidence to meet standards and keep production flowing with fewer interruptions.
