Square head bolts, also called machine bolts are threaded to receive a nut. These decorative bolts come in smooth, hammered and pyramid head styles.


About half the strength of medium-strength screws, these screws can be used for light duty fastening applications, such as securing access panels. Large flat sides make them easy to grip with a wrench and keep them from rotating in square holes. Material meets ASTM A307 specifications for quality. Length is measured from under the head.
