Basic threading

How to cut threads

Threading is a process of both external and internal machining of threads into a workpiece. Standardized specifications are available to determine the desired results of the threading process.


Threading is often performed on a lathe. Specifications such as thread height are critical in determining the strength of the threads. The material used is taken into consideration in determining the expected results of any particular application for that threaded piece. In external threading, a calculated depth is required as well as a particular angle to the cut.

To perform internal threading, the exact diameter to bore the hole is critical before threading.
