Which type of tool is a tap?

A tap is specifically designed to cut internal threads within a pre-drilled hole, allowing for the insertion of screws or bolts that match the created threads. This threading process is essential in various mechanical applications, enabling parts to be securely fastened together. The precise cutting action of the tap shapes the interior surface of the hole, ensuring that the threads conform to standard specifications for compatibility with standard fasteners. By using a tap, manufacturers and engineers can create reliable and robust connections in assembled components.
