Which tool is used with six-sided bolts?

The tool that is specifically designed to work with six-sided bolts is a nut driver. Nut drivers are sockets with a handle that fit over hexagonal nuts or bolts, allowing for a secure grip and turning capability. This is particularly useful because six-sided bolts have a hexagonal shape, making them compatible with the design of a nut driver.

In contrast, a Philips screwdriver is intended for use with screws that have a cross-shaped (Philips) head and would not fit on a six-sided bolt. A multimeter is an electronic measuring instrument used for measuring voltage, current, resistance, and other electrical parameters, making it unrelated to the task of turning bolts. A TORX screwdriver, while also a type of tool used for driving screws, is meant for screws that have a star-shaped pattern and would not fit a hexagonal bolt. Thus, the nut driver is the appropriate choice for handling six-sided bolts.
