The bolts are offered in grades 8.8, 10.9, and 12.9, with sizes spanning 1/2 inch to 2 inch diameters, and surface treatments that include black oxide and zinc plating to resist corrosion in harsh environments.
Manufactured from high-grade carbon or alloy steel, these bolts meet the mechanical properties defined by ASTM A490 for high-strength applications. Typical industry standards for such bolts include proof loads starting at 640 MPa for grade 8.8, with yield strengths scaling up to 1100 MPa for grade 12.9. Threads are usually coarse pitch per ASME B1.1, and head markings identify grade and manufacturer traceability.
These fasteners are sourced by fabricators and contractors in construction, automotive assembly, and industrial equipment manufacturing. Buyers commonly request FOT or FOB Ningbo terms with lead times of 30 to 45 days for container loads. Packaging is standard in 25 kg cartons or 500 kg pallets, with export crating available on request. Confirm exact MOQ and incoterms with the supplier before ordering.

Before ordering, verify that the bolts meet the exact ASTM A490 grade and size requirements for your project. Request third-party test reports for tensile strength, hardness, and Charpy impact values to ensure compliance with structural codes. Confirm whether the supplier’s bolts are Type 1 (alloy steel) or Type 3 (weathering steel) if atmospheric corrosion resistance is needed.
Discuss incoterms such as FOB Ningbo or CIF destination to clarify responsibility for freight and insurance. Lead times for ASTM A490 bolts can vary from 30 to 60 days depending on size and finish, so align production schedules accordingly. Payment terms may include T/T 30% deposit with 70% balance before shipment, but this should be negotiated directly with the supplier.
Inspect a sample lot for dimensional accuracy, thread fit, and surface finish before full shipment. For critical applications, arrange third-party inspection at the supplier’s facility or port of loading. Ensure packaging meets export standards to prevent damage during transit, and confirm that all documentation, including material test certificates (MTCs) and packing lists, accompanies the shipment.
