Square Head Bolts, ASTM A307, Coarse Thread, Plain Finish – 1/2 - 5/8 - 3/4"

Also known as:

Hex Bolts, Square Head Bolts

Square Machine Bolts are easily gripped by a hand wrench due to the large bearing area design. Hex Machine Bolts tend to be larger than hex bolts—up to 1-1/2" in diameter or more, and up to 20" in length. Hot Dip Galvanized Hex Nuts, which are tapped oversize, must be used with Hot Dip Galvanized Machine Bolts. The length of machine bolts is measured from under the head to the tip.
