Truthread Plug Thread Gauge (D/E) - UN - Right Hand - 2B - 1.1/4x20

The Truthread Plug Thread Gauge is a precision tool designed to verify the quality and compatibility of internal threads in threaded holes. It covers UNC, UNF, and UNEF standards, making it a versatile choice for machinists, quality inspectors, and maintenance teams. Its tapered plug design and built-in handle support fast, repeatable checks, helping you confirm a clean, proper thread fit before assembly.

Designed for right-hand threads and sized for 1.1/4x20 with 2B tolerance, this gauge delivers reliable results with minimal effort. The compact, tapered design and handy handle let you quickly insert the gauge into threaded holes, enabling swift confirmation of thread form and fit in busy workflows.

• Universal UNC/UNF/UNEF compatibility: Uses standard thread forms (UNC, UNF, UNEF) to quickly determine if internal threads meet the required size and pitch, reducing guesswork during inspection.
• Tapered plug with handle for easy insertion: The tapered tip and ergonomic handle streamline insertion into threaded holes, delivering consistent, repeatable checks without wobble or misreadings.
• 2B class, right-hand construction for durability: Built for long service life with tight tolerances, providing dependable measurements across daily use in manufacturing, quality control, and maintenance settings.

This gauge helps you accelerate quality checks, minimize rework, and ensure reliable thread performance in assemblies. By delivering clear, repeatable results, it supports efficient workflows, confident decisions, and consistent part-to-part compatibility across your production line.
