Which tool is most commonly used from a PC tool kit?

The screwdriver is the most commonly used tool in a PC tool kit because it is essential for assembling and disassembling computer components. Many parts of a PC, such as the case, motherboard, hard drives, and various drives, are secured with screws, making a screwdriver a fundamental tool for service technicians. This versatility allows technicians to quickly and effectively access or replace components, perform upgrades, or conduct routine maintenance on the computer system.

In contrast, while wire cutters, precision tweezers, and multimeters are useful for specific tasks, they are not as universally needed for general PC maintenance and repairs. Wire cutters might be more applicable in certain scenarios, like dealing with cables or making modifications to wiring. Precision tweezers are specialized tools used for handling small objects, often in intricate assembly tasks, but they are not frequently required in standard servicing. Multimeters are valuable for troubleshooting electrical issues but are not used as common tools during typical assembly and disassembly processes. Thus, the screwdriver stands out as the most essential and frequently utilized tool in a PC toolkit.
