Hex Machine Bolts

Hex Machine Bolts are large bolts that are usually at least 1/4" in diameter and larger. The head of the Hex machine bolt is similar to that of a Hex Cap Screw, but is absent the washer face that is found underneath the head of the screw. Often used in outdoor carpentry applications such as decks, patios, and similar construction, hex machine bolts are often manufactured with a galvanized hot dip finished for improved durability.
