About Shaanxi Flourish Industrial Co., Ltd. - Bolts Supplier in China

China, with five active product listings, offers a catalogue that includes washers, bolts, nuts, screws, and a combined hex head bolt & stud bolt. The bolt entry is recorded under HS code 7318.15 and specifies carbon steel and stainless steel that meet SAE J429 and ASTM A307 grades. The other fastener types are listed without HS codes but fall within the same HS Chapter 73 steel products. The supplier’s top categories are nuts, washers, bolts, and screws, reflecting a focus on standard fastening hardware.

The product set covers typical metric fasteners used in machinery, construction, and automotive assemblies. HS Chapter 73 encompasses iron and steel articles, and the listed items correspond to common specifications such as ISO 4032 for nuts and ISO 261 for screws. By providing both carbon steel and stainless steel options, the catalogue addresses corrosion‑resistant and high‑strength requirements across multiple end‑use sectors.

Product Range and Specialties of Shaanxi Flourish Industrial Co., Ltd.

The catalogue lists five fastener types: washers, standard bolts, nuts, screws, and a hex head bolt & stud bolt combination. Bolts are described as carbon steel or stainless steel conforming to SAE J429 and ASTM A307, which correspond to grades 4.6, 8.8, and 10.9 in metric practice. Typical dimensions for such bolts range from M4 to M24 diameter with lengths up to 150 mm, and thread pitches follow the ISO metric thread standard (e.g., 0.7 mm for M6).

Industry standards for these fasteners often reference ISO 898‑1 for mechanical properties, DIN 933 for hex bolts, and ISO 4032 for nuts. Washers are usually supplied in plain, serrated, or spring types, with thicknesses from 0.5 mm to 2 mm and diameters up to 30 mm. Screws may be pan‑head, flat‑head, or socket‑head, commonly meeting ISO 4762 or ISO 2010 specifications. Buyers typically request material test certificates that detail tensile strength, hardness, and coating condition.

Trade and Export Information - Shaanxi Flourish Industrial Co., Ltd.

China is among the world’s largest exporters of fasteners, and items classified under HS code 7318.15 are routinely shipped to North America, the European Union, and Southeast Asian markets. Buyers in these regions usually require compliance with ISO 9001 quality management, CE marking for EU entry, and REACH or RoHS declarations for environmental safety. Fasteners are typically packed in cardboard cartons, placed on wooden pallets, and loaded into 20‑foot or 40‑foot containers, with FOB Shanghai or CIF destination ports being common Incoterms.

Customs inspections often reference the HS Chapter 73 description and may request a mill test report (MTR) to verify grade and material composition. Export documentation generally includes a commercial invoice, packing list, certificate of origin, and any applicable test certificates. Seasonal demand peaks in Q2 for automotive assembly and Q4 for construction projects, influencing shipment schedules.

Sourcing from Shaanxi Flourish Industrial Co., Ltd. - Buyer Guidance

When sourcing from this supplier, buyers should request a mill test report that confirms the steel grade, tensile strength, and any heat‑treatment condition matching SAE J429 or ASTM A307. Samples of each fastener type - especially the hex head bolt & stud bolt - allow verification of thread tolerance, head dimensions, and surface finish. It is advisable to confirm the exact HS code classification (7318.15 for bolts) and ensure that the packaging meets the buyer’s palletizing and container loading requirements.

Typical minimum order quantities for metric bolts and nuts range from 500 to 1,000 pieces per size, with lead times of 15‑30 days after order confirmation. Buyers should verify that the supplier can provide ISO 898‑1 compliance certificates and, if required for the destination market, CE or RoHS declarations. Clarifying the preferred Incoterm (e.g., FOB Shanghai) and arranging pre‑shipment inspection can reduce the risk of non‑conformity.
