Truthread Thread Ring Gauge (NoGo) - UN - Right Hand - 2A - 1.1/8x16

The Truthread Thread Ring Gauge (NoGo) for UN threads is a precision inspection tool designed for quality control, maintenance, and manufacturing environments. Specifically calibrated for UN right-hand threads at 1-1/8 x 16 with a 2A class fit, it helps machinists, inspectors, and engineers verify that a threaded part stays within the required size range. This NoGo gauge provides a clear, repeatable check to confirm the thread is within tolerance.

Whether you are performing incoming inspection, in-process checks, or final QA, this gauge offers a reliable reference for UN threads, helping you prevent oversized components from moving forward in the process and ensuring consistent thread quality across batches.

• UN-thread specific calibration: Exquisitely tailored to UN threads, delivering precise, repeatable NoGo checks that reduce measurement guesswork.
• Minimum material condition verification: The NoGo test confirms the thread remains within the lower limit of the allowable size, helping catch parts that are too large before they reach assembly.
• Precise size and class fit: Designed for 1-1/8 x 16 UN right-hand threads in 2A class, providing a consistent reference for quality control and compatible with standard fixtures.

Using this gauge in your workflow improves inspection reliability, speeds up threaded-part checks, and reduces rework. It gives your team confidence that each part meets UN threading standards, supporting smoother assembly, better yield, and more predictable performance in the field.
