Import Bolts — Buy in Bulk from Supplier in China

China Jiangsu International Economic Technical Cooperation Corp. supplies structural bolts in grades 4.8, 8.8 and 10.9, alongside specialty fasteners including B7, A325 and A490. The source description cites tensile strength ratings as a key specification, with corrosion resistance and material compatibility also noted. These bolts are produced under batch-level quality control and shipped in carton and pallet packaging.

Grade 4.8 bolts typically offer a minimum tensile strength of 400 MPa and yield strength of 320 MPa, while grade 8.8 provides 800 MPa tensile and 640 MPa yield, standard for structural applications. Grade 10.9 pushes tensile strength to 1000 MPa with 900 MPa yield. B7 denotes a chromium-molybdenum alloy steel bolt for high-pressure service, A325 covers heavy hex structural bolts for steel joints, and A490 is the higher-strength equivalent with improved atmospheric corrosion resistance. Carbon steel remains the dominant material, with zinc plating or hot-dip galvanising as typical protective finishes per environment exposure requirements.

Construction contractors, automotive assemblers and machinery manufacturers form the core buyer segments for these fasteners. The bolts suit both static and dynamic load applications where joint integrity is critical. Buyers should confirm MOQ, lead times and Incoterms directly with the supplier, as these trade terms are not stated in the source data. Certificate of conformity and mill test reports should be requested for grade-critical orders.

China Jiangsu International Economic Technical Cooperation Corp. maintains its registered office at 11/f, Minfang Mansion, 189 Guangzhou Road, Nanjing, 210029, China. The supplier holds an imported tier classification and a harbor trust tier.

No verification badges, employee counts, annual revenue figures, or named client references appear in the profile.

The listing presents itself as a bolts exporter with specialisation across multiple fastener grades and standards. Buyers should note that no factory ownership status, production capacity, ISO certificate numbers, or specific quality management system accreditations are provided. The supplier's product range is stated as industrial-grade bolts for heavy-duty applications. Prospective buyers are advised to request company registration documents, factory audit reports, and sample test certificates before committing to volume orders.
