What are taps and dies used for in automotive contexts?

Taps and dies are specialized tools used for cutting threads on metals, which is essential in the automotive industry for creating strong mechanical connections. In this context, taps are used to cut internal threads in holes, allowing for the insertion of screws or bolts, while dies are used to cut external threads on rods or studs. This threading process is critical because it provides the necessary interlocking mechanism that ensures components are securely fastened together, which is vital for both safety and performance in vehicles.

In contrast, tools used for measuring distances, creating electrical connections, or polishing surfaces serve entirely different purposes and wouldn't fulfill the specific requirements for creating threaded connections essential to automotive applications.
