Truthread Thread Ring Gauge (NoGo) - UNEF - Right Hand - 2A - 1.1/2x18

Truthread Thread Ring Gauge (NoGo) for UNEF UN threads is a precision inspection tool designed to verify that threaded parts meet the lower-size limit. Specifically calibrated for UNEF right-hand threads, this gauge helps quality teams confirm the part’s minimum material condition so it remains within the allowable size.

Built for engineers, machinists, inspectors, and assembly personnel, it delivers quick, reliable go/no-go checks that reduce guesswork and rework. Use it during incoming inspection, in-process QC, or final assembly to ensure threaded components stay within tolerance before they are installed or shipped.

• UNEF Right-Hand Thread Compatibility (2A, 1-1/2 x 18): Designed to match the common UNEF right-hand thread size, ensuring accurate, repeatable checks straight out of the box.
• NOGO Lower-Limit Verification: Checks the minimum material condition to confirm the thread stays within the lower size bound, helping prevent parts from exceeding the maximum allowable size.
• Fast, Reliable Go/NoGo Testing: Calibrated for quick, decisive results with repeatable accuracy, reducing inspection time and downstream rework.

Using the Truthread NoGo gauge in your QC workflow speeds up inspections, minimizes guesswork, and strengthens tolerance control across batches. Its UNEF-specific design ensures compatibility with UN-threaded components, while the clear pass/fail results give your team confidence to move parts through quality checks efficiently.
