The product offered by Shanghai Fangyuan Fasteners Co., Ltd. is a heavy hex structural bolt designed for load‑bearing connections in steel frameworks. Each bolt is manufactured from medium carbon steel that is heat treated to meet the mechanical properties of ASTM A325 or A490 equivalents. The catalogue lists diameters from one‑half inch up to one‑and‑a‑half inch, conforming to ASME/ANSI B18.2.1 and ISO 7412 dimensional standards. The bolts are supplied either plain‑finished or with a hot‑dip galvanized coating as specified by the buyer.
A325 and A490 grades provide typical tensile strengths of approximately 120 ksi and 150 ksi respectively, which are standard for structural applications. The heat‑treated medium carbon steel offers a typical yield strength around 85 % of the tensile value, ensuring reliable performance under cyclic loads. In the fastener industry, these bolts are commonly paired with matching heavy hex nuts to form a complete assembly. Suppliers often finish the bolts with hot‑dip galvanising to improve corrosion resistance in outdoor structures.
Typical users include construction contractors, bridge engineers, and OEM manufacturers of industrial equipment. Shanghai Fangyuan Fasteners states that orders are packed in bulk cartons on solid wood pallets and shipped under FOB, CIF, CFR, EXW, DDP or DDU terms. The standard production lead time is thirty to forty days, with payment accepted by T/T, L/C or Western Union, subject to confirmation with the supplier.

Before placing an order, confirm that the bolts are produced from medium carbon steel and heat treated to the ASTM A325 or A490 specifications claimed by Shanghai Fangyuan Fasteners. Request a mill test report and, if possible, a material certification that details the chemical composition and mechanical properties. Verify the supplier’s registered address at 726 Lingzhao Road, Pudong, Shanghai and note the harbour verification tier, which indicates a basic level of trust.
Discuss the intended shipping arrangement early, selecting the incoterm that matches your logistics network - FOB for shipper‑managed freight, CIF or CFR if you prefer carrier responsibility to the destination port. Confirm the quoted lead time of thirty to forty days and ensure the payment method (T/T, L/C or Western Union) aligns with your finance policy. Ask for the exact pallet dimensions, carton count and any special handling instructions to avoid delays at customs.
Plan a quality assurance protocol that includes a pre‑shipment inspection of the finish, thread dimensions and bolt head geometry. Request a third‑party inspection report and a certificate of compliance with ASME/ANSI B18.2.1 and ISO 7412. If you require hot‑dip galvanised protection, ask for a coating thickness measurement. Arranging these checks before loading can reduce the risk of non‑conforming fasteners entering your production line.
