AI-Powered supplier vetting

SummaryHaoqiang Fastener is a combined manufacturing and sales supplier offering bolts, nuts, screws, and washers. It reports annual productivity of 20,000 tons for hex bolts and 5,000 tons for hex nuts, supported by wire drawing, cold heading, and thread tapping equipment. The supplier provides customization from samples and designs, full, minor, and flexible customization, and offers ODM and OEM services. However, it does not provide 3D software design services and reported no new products during the past year. Quality inspection instructions are reportedly implemented uniformly. Service procedures exist for supplier assessment, corrective actions, and complaint handling, but written records are unavailable. The supplier has no overseas warehouse, showroom, agent, or branch, although it has participated in the Canton Fair. Financial records identify reporting years but provide no assessable financial results in the supplied information.

Supplier typeThe supplier is identified as a combined company engaged in manufacturing and sales of fasteners, hardware tools, and steel, with import and export activities. Its offered products include bolts, nuts, screws, and washers.

R&D capabilityThe supplier provides ODM and OEM services, but it reported no new products during the past year, no SDK availability, and no 3D software design service. This shows some product-development service capability but also explicit limitations in innovation-related resources.

Production capacityThe supplier reports annual productivity of 20,000 tons of hex bolts and 5,000 tons of hex nuts, with wire drawing, cold heading, and thread tapping machines. Its manufacturing scope covers several standard fastener categories, supporting a documented production capability.

Customization capabilityThe supplier explicitly supports customization from samples and designs, full, minor, and flexible customization, and also provides ODM and OEM services for popular brands. These multiple stated service types indicate broad customization coverage.
