The Truthread Plug Gauge for UN (UNC/UNF/UNEF) holes is a precision instrument designed to measure the internal threads of threaded holes. Engineered to cover the Unified National Coarse (UNC), Unified National Fine (UNF), and Unified National Extra Fine (UNE F) standards, this Right Hand gauge is sized for 1x14 threads and produced to 2B-grade precision for consistently accurate readings. It’s an essential tool for machinists, inspectors, and maintenance professionals who need quick, reliable thread verification.
The gauge features a tapered insertion end and a comfortable handle, enabling fast, controlled checks without damaging the threads. Whether you're setting up equipment, validating parts, or calibrating your measuring process, this plug gauge helps you confirm fit, consistency, and quality with confidence.
- UNC/UNF/UNEF compatibility: Measures internal threads across the major Unified thread forms (UNC, UNF, UNEF) for quick, repeatable checks and reduced guesswork.
- Tapered insertion end with sturdy handle: Guides the gauge into threaded holes smoothly, protecting threads and speeding up inspections.
- 1x14 right-hand, 2B-grade precision: Sized for common 1x14 internal threads with right-hand orientation, built to tight tolerances for consistent results.
With the Truthread UN plug gauge, you gain fast, dependable verification of internal threads, reducing rework and assembly delays. The robust construction stands up to daily workshop use, while the tapered design and calibrated tolerances deliver repeatable readings you can trust. This gauge helps streamline quality checks, improve first-pass acceptance, and keep your manufacturing or maintenance workflow running smoothly.
