Hex head cap screws (HHCS for short), also called a hex cap are screws/bolts with six-sided heads with protruding flat sides for use with wrenches or sockets. These are a very common head choice when it comes to bolts and screws. Hex Head Cap Screws come in a large variety of sizes, lengths, and diameters; these heads allow the user to apply low to very high amounts of torque where a phillips or flat head would otherwise be stripped.
