Hex Head Bolt Materials 

It is important to differentiate between a hex head bolt and a hex head cap screw. Often people assume they are the same, but they are actually very different fasteners in terms of how they are manufactured, as well as from an application perspective. Regardless of your choice, hex heads offer strong, stable joints because of their large head service.
