About Fuyang Kaima Metal Co., Ltd - Steel Fasteners Supplier in China

China‑based Fuyang Kaima Metal Co., Ltd lists five active products across the steel fasteners and construction materials segments. The catalogue includes drywall screws, hex bolts and nuts, self‑tapping screws, self‑drilling screws and wood screws, with three items explicitly coded under HS 7318.14 for threaded fasteners of iron or steel. Materials are specified as carbon steel (including C1022A) and stainless steel grades 304/316, with zinc plating noted for the self‑tapping variant. The supplier’s top categories are recorded as Steel Fasteners, Construction Materials and Bolts, reflecting a focus on fastening hardware for building and industrial applications.

The product entries specify material families but do not provide dimensional data; typical industry practice for these items includes metric thread standards (M4‑M24) and head types such as pan, hex or socket. Zinc‑plated carbon steel offers corrosion resistance for indoor use, while stainless steel 304/316 provides higher resistance to moisture and chemicals, commonly required in outdoor or marine environments. The self‑drilling screw combines a drill point with a thread, eliminating pre‑drilling steps in metal sheet assembly.

Product Range and Specialties of Fuyang Kaima Metal Co., Ltd

Fuyang Kaima’s five listed items cover the core of the fastener market: drywall screws for gypsum board, hex bolts and nuts for structural connections, self‑tapping screws for sheet‑metal fastening, self‑drilling screws for direct metal penetration, and wood screws for timber work. In the broader industry, drywall screws are typically classified as coarse‑thread, steel, with a length range of 25‑50 mm and a head style of bugle or pan. Hex bolts conform to ISO 4014/4017 dimensions and are often supplied in grades 8.8 or 10.9, while self‑tapping and self‑drilling variants are produced in carbon steel C1022 (hardness ~45 HRC) or stainless grades 304/316, meeting ASTM A193 or A194 standards. Wood screws are commonly measured in diameter 3‑8 mm and length 25‑100 mm, with thread profiles suited to soft or hardwoods. Buyers usually request product data sheets that list thread pitch, tensile strength (e.g., 400‑800 MPa for carbon steel) and coating thickness (zinc ~5‑10 µm).

Trade and Export Information - Fuyang Kaima Metal Co., Ltd

China remains the world’s largest exporter of metal fasteners, with HS 7318.14 covering a broad selection of threaded steel products. Typical destination markets include the United States, the European Union, and Southeast Asian construction sectors, where building codes often reference DIN, ISO or ASTM fastener specifications. Importers generally expect compliance documentation such as ISO 9001 quality management certificates, CE marking for EU market entry, and material test reports confirming chemical composition and mechanical properties. Packaging for bulk fasteners is usually in cardboard cartons (e.g., 1 000 pcs per box) stacked on wooden pallets, allowing a 20‑ft container load of roughly 20 metric tonnes. Freight terms frequently use FOB Shanghai or CIF destination ports, with customs inspection focusing on HS code accuracy and coating compliance (e.g., RoHS limits on heavy metals).

Sourcing from Fuyang Kaima Metal Co., Ltd - Buyer Guidance

When sourcing from Fuyang Kaima, buyers should request a mill test certificate (MTC) that details carbon content, tensile strength and hardness for each steel grade. Confirmation of zinc plating thickness or stainless steel passivation should be obtained through a surface coating report. It is prudent to ask for a compliance matrix covering ISO 9001, CE and any applicable ASTM standards before placing an order, and to verify that packaging meets container loading plans (e.g., carton dimensions and pallet configuration).

What fastener types does Fuyang Kaima Metal list in its catalogue?

The catalogue contains drywall screws, hex bolts and nuts, self‑tapping screws, self‑drilling screws and wood screws, all classified under the steel fasteners segment.

Which HS code is associated with the self‑tapping, self‑drilling and wood screws?

All three products are listed under HS 7318.14, the code for threaded fasteners of iron or steel.

What materials are used for the self‑drilling and wood screws?

Self‑drilling screws are offered in carbon steel C1022A or stainless steel grades 304/316; wood screws are supplied in carbon steel or stainless steel 304/316.

Are any certifications explicitly held by Fuyang Kaima Metal?

The provided facts do not specify any certifications; buyers should request copies of ISO 9001, CE or ASTM compliance certificates if required for their market.

What typical specifications should a buyer verify for these fasteners?

Buyers normally check thread size (metric M4‑M24), tensile strength (e.g., 400‑800 MPa for carbon steel), coating thickness for zinc plating, and stainless grade certification for corrosion resistance.

What is the usual packaging method for bulk fasteners from China?

Fasteners are commonly packed in cardboard cartons, stacked on wooden pallets, allowing full 20‑ft container loads of approximately 20 tonnes.

Which regions commonly import Chinese steel fasteners?

Major importers include the United States, the European Union, and Southeast Asian countries with active construction and manufacturing sectors.

What documentation is typically required before shipment?

Importers usually request a mill test certificate, coating inspection report, and any relevant quality management certificates, along with a packing list and commercial invoice for customs clearance.
