They are manufactured to meet ASTM A307 specifications, which define the mechanical and chemical requirements for low-to-medium strength bolts used in non-critical joints where high tensile strength is not a primary concern.
The bolts are available in a range of finishes, including hot dip galvanized, zinc plated, and black oxide, to suit different environmental conditions. Carbon steel is the base material, with typical tensile strength ranging from 414 MPa to 586 MPa for Grade A. Sizes span from M6 to M80, or 1/4 inch to 3 inches, with custom dimensions available to meet specific project needs.
Buyers for these bolts typically include contractors, manufacturers, and distributors in the construction, infrastructure, and industrial sectors. The fasteners are often sourced in bulk for use in structural steel frameworks, machinery assembly, and general fabrication. Trade terms such as FOB or CIF are common, with packaging options including cartons, pallets, or bulk bags for efficient handling and shipping.

Before ordering, confirm the supplier’s ability to provide test certificates and compliance documentation for ASTM A307 GR.A specifications. Verify that the bolts meet the required tensile and yield strength values, as well as the chemical composition standards for carbon steel fasteners.
Clarify logistics details such as port of loading, Incoterms, and packaging preferences to ensure smooth delivery. FOB and CIF are common terms for fastener shipments, but buyers should confirm who is responsible for freight, insurance, and customs clearance. Discuss lead times, as production schedules may vary based on demand.
Inspect the bolts upon receipt for dimensional accuracy, thread quality, and finish consistency. Request documentation such as mill test reports and surface treatment certificates to confirm compliance with ASTM A307 standards. For critical applications, consider conducting third-party inspections or testing to verify the mechanical properties and corrosion resistance of the fasteners.
