Hex head drilling screws are characterized by their hexagonal-shaped heads, which allow for a superior grip and torque when fastening. This shape enables the use of a wrench or socket, providing better leverage than traditional flat or round heads. This feature is particularly advantageous in applications where high levels of torque are necessary to ensure a secure connection. Moreover, their design facilitates easier installation, making them a favorite among construction workers and DIY enthusiasts alike.
