Truthread Plug Thread Gauge (D/E) - UN - Right Hand - 2B - 1.5/16x8

The Truthread Plug Gauge (D/E) for UN threads is a precision instrument designed to verify the internal threads of holes. It supports UNC, UNF, and UNEF thread forms and is sized for 1.5/16x8 applications, making it ideal for engineers, machinists, inspectors, buyers, and hobbyists who need reliable, go/no-go thread checks.

With a tapered design and built-in handle, this right-hand gauge delivers quick, repeatable results while protecting threads during insertion. The 2B class specification aligns with common internal thread tolerances, ensuring consistent checks across parts and production runs.

• UN thread standards precision: Conforms to UNC/UNF/UNEF internal threads with tight tolerances for repeatable go/no-go checks across common hole sizes.
• Tapered plug design with handle for easy insertion: Guides entry into threaded holes smoothly and provides ergonomic control to speed up inspections without cross-threading.
• High-accuracy construction with class 2B tolerance: Manufactured to stringent accuracy specifications to ensure reliable measurements over daily use.

This gauge helps streamline thread inspection on production lines, maintenance tasks, and quality control audits. By delivering fast, confident checks of UNC/UNF/UNEF internal threads, it reduces rework, minimizes downtime, and supports clear measurement documentation. Its precision-built design means you can rely on consistent results part after part, making it a dependable core tool for machining, assembly, and inspection workflows.
