Import Heavy Hexagonal Bolt — Buy in Bulk from Supplier in China

The heavy hexagonal bolt supplied by Handan Yuanbo Metal Products Co., Ltd. is a fastening component designed for high load‑bearing applications. It is produced from carbon steel or alloy steel and meets strength grades 4.6 and 8.8 as indicated in the listing. The bolts feature a hexagonal head and are available in a range of standard dimensions to suit different thread sizes. Protective coatings are applied to improve corrosion resistance in demanding environments.

In the fastener industry, carbon steel bolts graded 4.6 provide a tensile strength of approximately 420 MPa, while grade 8.8 bolts reach about 800 MPa, aligning with ISO 898‑1 requirements. Typical hexagonal bolts incorporate a zinc or hot‑dip coating of 5‑15 µm thickness, which extends service life in humid or salty conditions. The design follows common metric thread standards, allowing compatibility with standard nuts and washers. Suppliers often ship these bolts in moisture‑resistant cartons to preserve coating integrity.

These bolts are frequently used in construction frameworks, automotive chassis, and heavy machinery assemblies where reliable fastening is critical. Importers typically request FOB or CIF terms and may negotiate minimum order quantities based on packaging size. While the listing mentions flexible MOQ options, the exact quantity should be confirmed directly with the supplier. Buyers should also verify any required certifications such as ISO 9001 before finalising the contract.
