About Shanghai Fangyuan Fasteners Co., Ltd. - Fasteners Supplier in China

Based in China, Shanghai Fangyuan Fasteners Co., Ltd. lists 24 active products across the fastener spectrum. The catalogue covers five top categories - screws, bolts, nuts, washers and general fasteners - and includes specific items such as drywall screws, machine screws, self‑drilling screws, chipboard screws and lag screws. A large portion of the bolt and nut line is classified under HS chapter 7318, with the code 7318.15 applied to hex tap bolts, square headed bolts, step bolts, heavy hex structural bolts, hex bolts and heavy hex bolts. Stamping parts are recorded under HS code 7318.29. The product set also features various washer types, including flat, hardened, spring/lock, square and F436 hardened washers.

The materials are detailed for several items: hex tap bolts are made from medium carbon steel grade 10.9, square headed bolts from carbon steel grade 8.8, and step bolts are supplied as hot‑dip galvanized carbon steel conforming to ASTM F1554 grade 36. Heavy hex structural bolts use medium carbon steel heat treated to ASTM A325/A490 equivalents, while stainless steel options for hex bolts meet grades 304 or 316. The nut range includes standard hex nuts, heavy hex nuts, flange nuts and nylon‑insert lock nuts, each typically fabricated from carbon steel grades 8.8 or 10.9. Overall, the listing reflects a focus on mechanically robust fasteners suitable for construction, machinery and automotive applications.

Product Range and Specialties of Shanghai Fangyuan Fasteners Co., Ltd.

The screw selection follows common industry standards such as ISO 7045 for metric wood screws and ISO 14579 for self‑drilling variants. Typical drywall screws are supplied in diameters from 3.5 mm to 5 mm with lengths ranging 25 mm to 100 mm, while chipboard screws often use a coarse thread profile for particle board applications. Machine screws are offered in full metric thread series (M4 - M12) and conform to ISO 261/262 dimensions. Fasteners are commonly graded to tensile strengths of 800 MPa for grade 8.8 and 1040 MPa for grade 10.9, with hardness values around 250 HB for medium carbon steel.

Bolts and nuts in the catalogue align with ISO 898‑1 for mechanical properties and DIN 933/934 for hex head dimensions. Heavy‑hex structural bolts and step bolts are typically supplied in lengths up to 200 mm and diameters up to M24, with hot‑dip galvanised finishes providing a minimum coating thickness of 55 µm. Washers such as flat, square and hardened types are sized to match standard bolt diameters, with F436 hardened washers meeting a hardness of 360 HB. Lock washers and nylon‑insert nuts are used to prevent loosening in vibration‑prone assemblies, a standard practice in automotive and machinery fastening.

Trade and Export Information - Shanghai Fangyuan Fasteners Co., Ltd.

China is a major global exporter of fasteners, and products classified under HS 7318.15 and 7318.29 are routinely shipped to North America, the European Union, and Southeast Asian markets. Importers in construction, automotive manufacturing, and industrial equipment sectors typically require certificates of origin, mill test reports and compliance with standards such as ISO 9001 and CE marking. Anti‑dumping investigations on Chinese fasteners have made customs documentation and accurate HS coding essential for smooth clearance.

Standard export logistics involve FOB Shanghai or Ningbo ports, with cargo consolidated in 20‑foot or 40‑foot containers and packed in cardboard boxes or wooden crates. Buyers often request that shipments be accompanied by a declaration of conformity to REACH and RoHS directives, especially for stainless‑steel or coated items. Shipping terms commonly used are CIF or DDP to the buyer’s destination port, and freight forwarders handle the required mechanical inspection reports where applicable.

Sourcing from Shanghai Fangyuan Fasteners Co., Ltd. - Buyer Guidance

When sourcing from Shanghai Fangyuan Fasteners, buyers should request material test certificates that specify tensile strength, yield point and hardness for each grade (e.g., 8.8, 10.9, 12.9). For galvanized bolts, a coating thickness report complying with ISO 1461 is advisable, while stainless‑steel bolts should be accompanied by a corrosion resistance test result. Mill test reports should list chemical composition, especially for alloy steel stamping parts where chrome‑molybdenum or boron content is critical.

Sample orders of typical sizes - for example, a 500‑piece pack of M8×30 mm hex bolts or a 200‑piece set of 4 mm drywall screws - allow verification of thread fit and head geometry before larger commitments. Minimum order quantities generally start at 500 units for screws and 200 units for bolts, with lead times ranging from 15 to 30 days after order confirmation. Buyers should also confirm packaging dimensions (e.g., 1 m³ per 20‑ft container) and request a packing list that matches the HS codes provided.

What fastener categories does Shanghai Fangyuan Fasteners offer?

The supplier lists products in five categories - screws, bolts, nuts, washers and other fasteners - covering items such as drywall, machine and self‑drilling screws, hex tap and heavy‑hex bolts, various nut types and multiple washer designs.

Which HS codes are used for the bolt and stamping part products?

Bolts, nuts and related hardware are classified under HS code 7318.15 (iron or steel fittings), while stamping parts are recorded with HS code 7318.29 (other iron or steel products).

What material grades are specified for the hex tap bolts and step bolts?

Hex tap bolts are made from medium carbon steel grade 10.9, and step bolts are supplied as hot‑dip galvanized carbon steel meeting ASTM F1554 grade 36 specifications.

What certifications are typically required for Chinese fastener exports?

Importers usually request ISO 9001 quality management certification, CE marking for EU markets, and compliance documents for REACH and RoHS. Mill test certificates and certificates of origin are also standard.

What are the typical dimensions and standards for the drywall screws in the catalogue?

Drywall screws are offered in diameters from 3.5 mm to 5 mm and lengths between 25 mm and 100 mm, conforming to ISO 7045 metric wood‑screw specifications.

How are the fasteners packaged for international shipment?

Products are packed in reinforced cardboard boxes or wooden crates, with quantities arranged to fill standard 20‑ft or 40‑ft containers. Packing lists reference the appropriate HS codes and include weight and volume details.

What lead time and minimum order quantities should a buyer expect?

Lead times are generally 15 - 30 days after order confirmation. Minimum order quantities are typically 500 units for screws and 200 units for bolts, though larger batch sizes may be required for custom grades.
