A325 Heavy Hex Bolts

Intended for structural bolting uses, ASTM A325 heavy hex bolt dimensions range from ½ to 1½ inches in diameter. ASTM A325 is an international standard for heavy hex structural bolts set by ASTM International (American Society for Testing and Materials). As a hex bolt standard, it was replaced by ASTM F3125 in 2016, but there is still quite a demand for A325 hex bolts. Additionally, the same bolt head markings are used to avoid any confusion.
