The Truthread Plug Thread Gauge (D/E) for UN threads is a precision instrument designed to measure the internal threads of threaded holes with accuracy and repeatable results. It covers the Unified National standards (UNC, UNF, UNEF), making it a versatile tool for engineers, machinists, quality inspectors, and technicians who need quick, trustworthy thread checks. The gauge is built to support right-hand thread measurements and 2B tolerance, providing dependable performance in everyday workshop use. Its tapered design and integrated handle enable smooth, guided insertion into holes for fast assessment of thread fit.
- UN Thread Standards Coverage: Conforms to UNC, UNF, and UNEF internal-thread forms, enabling reliable checks across the most common UN thread types with a single, easy-to-use gauge.
- Tapered Design with Insertion Handle: The tapered body and easy-grip handle guide the gauge into threads cleanly, helping prevent cross‑threading and speeding up inspections.
- High Precision, Tight Tolerances: Manufactured to tight tolerances to deliver repeatable measurements and consistent results, reducing guesswork and rework in quality control.
This plug gauge is sized for precise evaluation of internal threads, empowering you to verify hole quality, shorten inspection times, and ensure reliable assembly with UNC/UNF/UNEF fasteners. Its durable construction supports daily use in manufacturing, maintenance, and QA environments, giving you confidence that thread checks are accurate and repeatable every time.
