Truthread Plug Thread Gauge (D/E) - UN - Right Hand - 2B - 1.3/8x16 FLH and a controlled tolerance supportsThe Truthread UN Plug Gauge is a precision instrument designed to measure the internal threads of threaded holes. It conforms to UNC, UNF, and UNEF thread standards, providing reliable and consistent checks across the most common UN thread forms. Configured as a right hand gauge with 2B tolerance and a size of 1 3 8 x 16, it features a tapered measuring section and a practical handle for easy insertion. This design supports quick, repeatable checks of
