Supplier typeThe supplier is identified as Handan Yanzhao Fastener Manufactory Co., Ltd., a combined company specializing in R&D and production of high-strength fasteners. Its stated facility size, workforce, equipment base, and manufacturing scope support classification as a manufacturer rather than only a trading intermediary.

After-Sales capabilityThe supplier reports inventory capability, accepts several service quotation and payment terms, and states a service location near Tianjin Port. However, it has no overseas warehouse, showroom, agent, branch, or overseas-service country coverage, and has no written service-capability assessment procedures or approved supplier list, indicating limited documented overseas after-sales infrastructure.

Production capacityThe supplier reports a 40,000-square-meter site, more than 100 employees, over 100 advanced production machines, shot blasting, wire drawing, molding, heat treatment, and stud production facilities, inventory capability, five quality inspectors, and lead times within 15 working days in both seasons. These stated resources and performance indicators support substantial production capacity, although the lack of a valid contract with associated subcontractors is a control weakness.

Customization capabilityBoth R&D and design-capability records explicitly list customization from samples, designs, full customization, minor customization, and flexible customization. The supplier also reports ODM availability, providing direct evidence of broad customization support.
