The 'head' of the bolt refers to its top part that sits above the threaded shaft. It's the part that provides the gripping surface for the tool used in installation or removal. The hexagonal shape offers several advantages over other head designs. Firstly, it allows for better torque application, enabling precise tightening without slipping. Secondly, the six-sided profile can accommodate larger wrenches or sockets, which can generate more torque, ideal for heavy-duty applications.
