Truthread Plug Thread Gauge (D/E) - UNC - Right Hand - 2B - 5/8x11

The Truthread Plug Thread Gauge is a precision tool designed to measure the internal threads of threaded holes. It is sized for 5/8x11 right-hand UNC threads and is specified for the 2B tolerance class, making it ideal for checking holes that follow Unified National Coarse (UNC), Unified National Fine (UNF), and Unified National Extra Fine (UNEF) standards. This gauge helps you quickly confirm that internal threads are within spec, supporting consistent assembly and quality control across parts.

Ideal for engineers, machinists, quality inspectors, and maintenance technicians, this plug gauge delivers reliable, repeatable results during setup, inspection, and calibration workflows. Its tapered design and built-in handle enable smooth insertion into threaded holes, allowing you to evaluate thread fit with speed and confidence—without guesswork.

• Standards-aligned precision: Built to UNC/UNF/UNEF thread standards, providing accurate cross-reference checks across common hole sizes so you can verify compatibility quickly.
• Ergonomic, quick-insertion design: Tapered tip with a convenient handle lets you insert the gauge smoothly into holes, delivering consistent readings with fewer handling errors.
• Consistent, calibrated readings: Tight tolerances and precise construction support repeatable measurements and straightforward calibration routines, reducing rework and downtime.

In practice, this gauge helps you validate thread quality during part intake, machine setup, and routine maintenance. By delivering fast, dependable checks, it streamlines workflows, supports better decisions in assembly and quality control, and provides a trusted reference point for maintaining dimensional accuracy across your threaded components.
