ASTM A325 Rivets

ASTM A325 Rivets refer to structural steel rivets (historically covered by specifications like A502) used for permanent, high-strength connections in structural steel applications. While high-strength bolting (A325 bolts) has largely replaced rivets in modern construction, we supply rivets manufactured from material with mechanical strength equivalent to the ASTM A325 structural specification. These rivets are made from carbon steel, capable of forming a robust, high-integrity permanent joint that resists shear and tension loads. They are used in structural framework, bridge construction, and machinery assembly where a strong, permanent, vibration-resistant connection is required.
