ASTM A307 Grade A Rivets

ASTM A307 Rivets are permanent fasteners made from low-carbon steel and are historically used to create highly robust, permanent connections between two or more structural or mechanical components. While the A307 specification primarily addresses bolts and studs, the same low-carbon steel material is often used for general-purpose rivets (especially structural rivets like high-button or cone-head types) when moderate strength is required. The rivet is installed by inserting it into a pre-drilled hole and deforming the plain tail end into a new, finished head, often when hot (hot riveting) to form a tight, load-bearing joint. These fasteners are widely used in older structural steel construction, boilers, and machinery where a permanent and tamper-proof connection is desired. Zeron Fasteners manufactures and supplies high-quality A307 Rivets, adhering to specified dimensional and material requirements for reliable performance.
