About Xingtai Mindu Industrial Co.ltd - Nuts Supplier in China

Xingtai Mindu Industrial Co.ltd is based in China and currently lists five active products in its catalogue. The product set comprises hex bolts conforming to DIN 933, DIN 931, ISO 4014 and ISO 4017, hex nuts meeting DIN 934 and ISO 4032, hex socket head cap screws to DIN 912, hexagonal slotted nuts to DIN 935, and threaded rods to DIN 975. Each item follows internationally recognised DIN or ISO standards, which are routinely classified under HS chapter 73, heading 7318 for threaded fasteners. The catalogue therefore covers both external and internal thread fasteners commonly used in machinery, automotive and construction applications. The supplier’s catalogue does not include other fastener types such as washers or rivets.

Product Range and Specialties of Xingtai Mindu Industrial Co.ltd

The listed products span the principal categories of metric fasteners: bolts, nuts, socket head cap screws and threaded rods. In the fastener market, hex bolts and nuts are typically supplied in property classes 8.8, 10.9 or 12.9 for carbon‑steel variants, while stainless‑steel options follow A2 (304) or A4 (316) grades. Surface treatments most often include hot‑dip zinc plating, black oxide or plain finish, each affecting corrosion resistance and tensile strength. Standard dimensions range from M4 to M24 for the hex series, with lengths from 20 mm up to 200 mm for bolts and rods, and head heights that comply with the corresponding DIN specifications. Buyers usually specify thread tolerance (e.g., 6g for external threads) and hardness requirements (e.g., 30 HRC for medium carbon steel).

Trade and Export Information - Xingtai Mindu Industrial Co.ltd

China is a leading exporter of metric fasteners, and products classified under HS 7318 are shipped to Europe, North America, Southeast Asia and the Middle East in 20‑ft or 40‑ft containers. Common Incoterms for Chinese fastener suppliers are FOB Tianjin or CIF major ports such as Shanghai and Ningbo. Importers typically request certificates of conformity such as ISO 9001 quality‑management certification, CE marking for EU markets, and test reports complying with EN 10204 (type 3.1) or ASTM A193 for mechanical properties. Packaging standards include paperboard cartons with inner cardboard dividers, or bulk wooden crates for larger quantities, each sealed for moisture protection. Export controls in China require customs declaration of HS 7318 items and may involve pre‑shipment inspection by agencies like SGS or Bureau Veritas, especially for high‑grade (10.9/12.9) fasteners.
