Square head bolts, also called machine bolts are threaded to receive a nut. These decorative bolts come in smooth, hammered and pyramid head styles.
In the 1830's, square headed nuts were superseded by hex head. The widespread use of hex nuts and bolts came because of innovation in engineering and metallurgy. Hex nuts and the tools to use them require close tolerances, while square heads required less accurate tolerances.
