A torque wrench is a tool used for hexagonal bolts and hexagonal nuts, whereas a torque driver is a tool that allows you to manage the torque when tightening screws. Screws are components that can cause accidents if used incorrectly, such as to prevent forgetting to tighten screws or breakage due to over-tightening. If there is a specified torque specified by the designer, use a torque screwdriver or torque wrench to tighten with the appropriate torque.
