Bolt heads come in various shapes, with square, hex, and slotted hex washers, and socket caps being the most popular. The square head bolts were the first to be used.
Square heads are composed of a shaft that can withstand rotation when a torque is applied, followed by a square depression on the head. Hex heads have become more prevalent; however, square heads are still in use.
To provide torque, hexagonal heads are used with a wrench or a spanner. In this reading, we’ll explore the various types of bolt heads and their uses.
