What is the shape of the tip of a hex screwdriver?

The tip of a hex screwdriver is designed to fit into hexagonal-shaped screw heads. This unique shape allows the screwdriver to engage securely with the fastener, providing better torque and reducing the risk of stripping the screw compared to other shapes. The hexagonal design, consisting of six flat sides, allows for a better grip and transfer of force, making it an efficient tool for fastening or loosening hex screws that are widely used in various applications, especially in machinery and automotive work. This distinctive shape is what differentiates a hex screwdriver from other types, such as star, square, or flat screwdrivers, which are designed for different screw types.
