The supplier demonstrates broad customization and ODM capabilities, reports new products within the past year, and provides OEM services for recognized brands. Production evidence includes bolt productivity of 60,000 tons and 10 quality inspectors, supported by inspection instructions and quality procedures. Service management procedures cover supplier assessment, corrective and preventive actions, and customer complaints.

Supplier typeThe supplier is identified as a combined business entity and limited company operating in Handan, Hebei, China. Its stated business scope is the processing and sale of standard parts and power hardware, which is directly relevant to fastener supply.

After-Sales capabilityThe supplier has written and followed procedures for service-capability assessment, corrective and preventive actions, and customer complaints. It also reports inventory capability and multiple service quotation and payment terms, but lacks an overseas warehouse and showroom; overall after-sales capability is evidenced, although international physical service coverage is limited.

R&D capabilityThe supplier reports new products within the past year, provides ODM services, and has broad design-service capabilities. It also uses ERP for production, procurement, quality control, and logistics, while enterprise digital-process construction and big-data-related development are reported; however, no SDK is available.

Production capacityProduction evidence includes stated bolt productivity of 60,000 tons, 10 quality inspectors, thread rolling and cold heading equipment, and uniformly followed finished-product inspection instructions. Inventory capability and peak- and off-season lead-time statements support fulfillment capability, but the absence of a valid contract with related subcontractors is a documented capacity-management weakness.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. These capabilities are reported consistently across the R&D and design-service information, with ODM availability further supporting customized product development.

Client casesThe supplier states that it provides OEM services for recognized brands, which is evidence of brand-related customer experience. No customer names, project descriptions, order history, or independently verifiable case details are provided, so the depth of customer cases cannot be fully evaluated.
