Truthread Thread Ring Gauge (NoGo) for UN threads — Right Hand, 2A, 1-3/8x8 — is a precision inspection tool designed to verify threaded parts meet UN standards. Calibrated to confirm the thread is within tolerance, it enables quick, reliable assessments during manufacturing, quality control, and maintenance tasks.
This NoGo gauge specifically checks the minimum material condition, ensuring the part remains within the lower limit of the size spec. This makes it ideal for confirming threaded components do not exceed the maximum allowable size, helping prevent assembly interference and out-of-spec issues.
- UN Thread Precision: Calibrated specifically for UN threads to reliably confirm the thread is within tolerance, reducing guesswork and rework in production.
- NoGo Minimum Material Check: Verifies the lower limit of the size, ensuring parts are not oversized beyond the maximum spec and that the material condition meets the intended tolerance.
- Durable Ring with Knurled Edge: Rugged, easy-to-grip design for repeatable, fast checks in busy workshops, delivering long service life and consistent results.
By delivering fast, reliable NoGo checks for UN threads, this gauge helps you speed up QC workflows, reduce rework, and improve the consistency of threaded assemblies. The result is fewer delays, better fits, and increased confidence in your parts and processes.
