These hex bolts have hexagonal heads and are for general purpose applications with a socket type installation tool or standard wrench. The standard bolt is compatible with standard nuts and washers of the same thread pitch， grade， and finish. Grade 8 bolts have a higher strength and are to be used with Grade 8 nuts. An alternative for using hex bolts without nuts is to place them directly into a compatible female threaded receptacle. They require a pre drilled hole or pre-tapped hole with compatible female thread. Available in various materials， grades， and finishes.
