Description
Thread Gauge Go 2 3/4-4 UNC 64-823163
This high-precision Go thread gauge is an indispensable tool for verifying external threads with the dimension 2 3/4-4 UNC. It is used to ensure that the major diameter of a threaded component does not exceed the specified tolerance. As a “Go” gauge, it must pass over correctly manufactured threads, guaranteeing that they meet the minimum requirements for fit.
The thread gauge is manufactured with the highest precision from durable steel to ensure long service life and reliable measurement. It has undergone careful calibration to comply with applicable standards for UNC threads (Unified National Coarse), ensuring accuracy during quality control. This type of measuring instrument is critical in manufacturing processes where thread precision is essential.
