These are ASTM A490 Type 1 heavy hex structural bolts manufactured from carbon or alloy steel, designed to meet the high-strength requirements of critical structural steel connections in bridges, buildings, and heavy infrastructure. The bolts conform to ASTM A490/A490M standards, with size availability ranging from M6 to M80 and 1/4" to 3" as per customer requirements, ensuring compatibility with a wide array of structural applications. Finishes include zinc plating in multiple colours, hot dip galvanized, Geomet, Dacromet, anodization, nickel plating, zinc-nickel plating, and PTFE coatings for enhanced corrosion resistance.
The material composition is tailored for Type 1 specifications under ASTM A490, which mandates a minimum tensile strength of 1035 MPa and yield strength of 895 MPa, typical for alloy steel grades used in high-load applications. Standard thread lengths and head configurations adhere to heavy hex structural bolt dimensions, with typical tolerances for diameter, length, and thread pitch controlled to ensure precise fitment in pre-drilled structural steel components. These bolts are commonly used in conjunction with ASTM A563 or A194 heavy hex nuts and flat washers for complete structural assemblies.
Primary buyers include structural steel fabricators, construction firms, and engineering contractors sourcing fasteners for projects requiring high tensile strength and durability. The bolts are traded internationally in bulk, typically priced per metric ton, with packaging options such as steel drums, wooden crates, or palletized boxes to suit long-distance shipping. Lead times and MOQs vary by order size and finish, with hot dip galvanized and specialty coatings often requiring additional processing time.

Before ordering, verify the bolt dimensions, material composition, and finish specifications to ensure they match your project’s structural requirements. Confirm that the supplier can provide test certificates or mill reports for the ASTM A490 Type 1 grade, as these documents validate the bolts’ mechanical properties and compliance with the standard.
Discuss logistics details such as lead times, which may vary depending on the finish and order volume, with hot dip galvanized or specialty coatings often requiring additional processing time. Clarify Incoterms, particularly whether the price includes delivery to your port (e.g., CIF or FOB Ningbo), and confirm payment terms to avoid delays in shipment.
Request quality checks such as dimensional inspections, coating thickness measurements for corrosion-resistant finishes, and material certifications to ensure the bolts meet ASTM A490 Type 1 standards. For critical applications, consider third-party inspection or testing for tensile strength, yield strength, and hardness to verify the bolts’ performance under load.
