Heavy Hex Structure Bolts A490m 10s
The Heavy Hex Structure Bolts A490M 10s supplied by Ningbo S&D Metalwork Co., Ltd. are built to meet ASTM A490M specifications, delivering high‑strength performance for structural connections. They are offered in metric diameters from M12 up to M36 and feature a heavy‑hex head that conforms to ISO 4014 dimensions. The bolts can be finished with Dacromet or black coating, providing corrosion protection suited to outdoor installations. Alloy steel grades 40Cr and 35CrMo are used as the base material, ensuring the required hardness and toughness.
In the fastener market, A490M bolts are recognized for their combination of yield strength around 940 MPa and tensile strength near 1080 MPa, which makes them suitable for bridge girders, high‑rise building frames and heavy machinery. Typical surface‑treatment options include Dacromet for marine environments and black phosphate for general corrosion resistance. The hex head design offers superior torque transmission and reduces the risk of rounding during installation, a common requirement in large‑scale construction projects.
These bolts are purchased by structural engineers, construction contractors and equipment manufacturers who need reliable fastening under cyclic loads. Ningbo S&D Metalwork Co., Ltd. indicates flexible MOQ and offers shipment under FOB or CIF terms. The company can provide ISO and SGS test certificates upon request, and accepts payment by L/C or T/T as per the buyer’s preference.

Sourcing Heavy Hex Structure Bolts A490m 10s from Ningbo S&D Metalwork Co., Ltd. - China Import Guide
When preparing to order, confirm that Ningbo S&D Metalwork Co., Ltd. holds a harbor trust tier status and request the latest material test reports and any relevant ISO or SGS certificates. Verify that the bolts conform to ASTM A490M and that the chosen coating matches the environmental conditions of your project. These checks help ensure the fasteners will satisfy structural performance and durability requirements.
Discuss logistics early; the supplier can ship under FOB or CIF terms, but exact lead times are not published and should be negotiated per order. Clarify the preferred Incoterm, container loading plan and any freight forwarder specifications. Agree on payment conditions such as L/C or T/T before production begins to secure the transaction.
Upon arrival, arrange a third‑party inspection to check dimensions, hardness and coating thickness against the supplied certificates. Request a final inspection report and a certificate of conformity before releasing the goods. Proper documentation, including packing lists and test reports, facilitates customs clearance and ongoing quality assurance for the imported bolts.
