Import Bolt — Buy in Bulk from Supplier in China

Zhejiang Zeen Fasteners Co., Ltd supplies bolts from their facility in Shaoxing, Zhejiang Province, positioned within the Yangxun Qiao Special Features Industrial Zone. The listing indicates industrial-grade manufacturing aimed at construction, manufacturing, and assembly applications, with stated compliance to international standards for engineering use. No specific bolt grades, tensile classes, or dimensional tables are provided in the source data, so buyers should request the exact ISO or DIN class, thread pitch, and mechanical properties for their intended application.

The source description references high-strength materials with corrosion resistance, though no specific steel grades, coating specifications, or hardness values are confirmed. Typical industrial bolts from Chinese fastener manufacturers in this region are produced from carbon steels such as 4.8, 8.8, or 10.9 grade per ISO 898-1, with surface treatments including zinc plating, hot-dip galvanising, or dacromet for corrosion protection. Thread forms are typically metric coarse (ISO 261) or fine (ISO 262), with hexagon heads conforming to ISO 4014 or ISO 4017 depending on whether the bolt is partially or fully threaded.

Primary buyers span construction contractors, automotive assembly plants, machinery manufacturers, and general engineering workshops. The supplier mentions FOB and CIF Incoterms, indicating willingness to handle export logistics from Chinese ports, though buyers must confirm the specific port of dispatch, packing method, and whether container load or break-bulk shipment applies. Response rate data shows zero recorded responses, so direct enquiry is essential to establish current availability, minimum order quantities, and production lead times.

Zhejiang Zeen Fasteners Co., Ltd operates from the Yangxun Qiao Special Features Industrial Zone in Yangxun Qiao Town, Shaoxing, Zhejiang Province, China. The location places it within one of China's densest concentrations of fastener manufacturing, with access to raw steel supply chains and export infrastructure through Ningbo or Shanghai ports. The supplier carries an imported tier designation and harbor trust tier, with a response rate of zero percent and no recorded average response hours. Buyers should treat this as a signal to initiate direct contact early and verify active operations before relying on quoted timelines.

The company profile does not state year of establishment, production capacity, employee count, or specific quality certifications held. No client references, export markets, or factory audit information is provided. The listing emphasises industrial-grade bolts for construction and manufacturing, with packaging designed for secure shipping. Buyers are advised to request a current company brochure, ISO 9001 certificate validity, and sample bolts with mill test certificates before committing to volume orders.
