ASTM A490 Heavy Hex Bolt from Ningbo Beilun Milfast Metalworks Co. Ltd is a high-strength structural fastener manufactured from quenched and tempered alloy steel. Designed for demanding applications, it meets ASTM A490 specifications, which mandate a minimum tensile strength of 120 ksi (827 MPa) and is commonly used in structural steel connections for bridges, buildings, and heavy equipment. The heavy hex head provides increased bearing area and wrench clearance, while the hot dipped galvanized finish enhances corrosion resistance for outdoor and industrial environments.
The bolt’s alloy steel composition is heat-treated to achieve the required mechanical properties, including a minimum yield strength of 90 ksi (620 MPa) and elongation of 14% in 2 inches. Standard industry practice for ASTM A490 bolts includes Charpy V-notch impact testing at -20°C to ensure toughness, with typical values exceeding 20 ft-lb. The bolts are threaded to ASME B1.1 standards, with typical thread lengths conforming to ASTM F3125 for structural applications.
These bolts are exported globally under HS Code 7318.15, primarily for use in construction, infrastructure, and heavy machinery projects. Buyers typically source them in bulk for large-scale applications, such as bridge construction or tower fabrication. The hot dipped galvanized finish adds a zinc coating of 45-85 µm, providing long-term protection against rust in humid or saline environments.

Before ordering ASTM A490 heavy hex bolts from Ningbo Beilun Milfast Metalworks Co. Ltd, verify the bolts’ mechanical properties, including tensile strength, yield strength, and Charpy impact energy. Request mill test reports to confirm compliance with ASTM A490 and ensure the hot dipped galvanized finish meets your corrosion resistance requirements for the intended environment.
Logistics details such as lead time, incoterms, and payment terms are not specified in the supplier’s profile. Confirm the supplier’s ability to meet your project timeline and preferred incoterm, such as FOB Ningbo or CIF to your destination port. Clarify payment methods, including letters of credit or advance payments, and ensure the port of loading is explicitly agreed.
For quality assurance, conduct third-party inspections to verify the bolts’ dimensions, thread accuracy, and zinc coating thickness. Request documentation such as material test certificates, heat treatment records, and galvanizing reports. If the bolts are for critical applications, consider additional testing such as hardness or torque-tension tests to ensure performance under load.
