The Truthread Plug Thread Gauge (D/E) - UNF - Right Hand - 2B - No. 12x28 is a precision tool designed to measure the internal threads of threaded holes. It covers the Unified National Coarse (UNC), Unified National Fine (UNF), and Unified National Extra Fine (UNEF) standards, making it a versatile choice for production, inspection, and maintenance environments. The tapered design with a handle allows for smooth insertion into holes to quickly verify thread fit and quality.
Built for reliable, repeatable results, this gauge is engineered with tight tolerances to ensure consistent measurements across shifts and operators. Its right-hand orientation and 2B sizing align with common threading practices, supporting accurate assessment of hole quality during assembly and quality control checks. If you’re calibrating gauges for precise results, this plug gauge provides a dependable reference point.
- UNC/UNF/UNEF compatibility: Precisely aligned to the three Unified National thread standards, enabling fast, one-tool validation of internal threads.
- Tapered design with easy insertion: The tapered tip and integral handle let you insert quickly and assess thread engagement without force or guesswork.
- Right Hand, 2B sizing for reliable results: Sized and oriented for typical manufacturing and inspection workflows, delivering consistent measurements and repeatable results.
Using this gauge helps you confirm hole compatibility with fasteners, reduces guesswork, and speeds up inspection workflows. Its precise, repeatable measurements support quality control, calibration, and consistent assembly performance, giving you confidence in every threaded hole you verify.
