ShanghaiKey features
Full Bearing Flange Design: The integrated flange eliminates the need for a separate washer, spreading clamp load evenly and preventing surface damage on soft or coated substrates.
No More Loosening Under Vibration: Stop replacing fasteners that back out on machinery or vehicles-the serrated flange face bites into the mating surface for reliable, maintenance-free clamping.
30% Faster Assembly: The flanged head removes a separate washer-fitting step, cutting installation time by roughly a third compared to standard hex bolts with loose washers.
Built for Harsh Industrial Environments: From wind farm towers to petrochemical piping, the wide range of coatings (Zinc, Black Oxide, Dacromet, PTFE) keeps performance consistent.
Higher Load Capacity: The wider bearing surface distributes clamping force over roughly 1.5x the contact area of a conventional hex bolt, reducing the risk of pull-through on thin or brittle materials
Full M5-M20 Size Coverage: One supplier for your entire bolt range-from small M5 fasteners to heavy-duty M20 bolts up to 200mm long-simplifies sourcing and reduces supplier fragmentation.
Direct-From-Factory Pricing: As the actual manufacturer-not a trading company-we cut out the middleman, giving you factory-direct pricing and full control over lead times and quality.
ISO9001-Certified Quality System: Every batch is produced under an ISO9001-certified quality management system, ensuring consistent dimensional accuracy and mechanical properties from order to order.
BV, ABS & CE Certified for Global Compliance: Our fasteners are certified by BV, ABS, and CE, meeting the marine, industrial, and European regulatory standards your projects require.
Full Traceability with MTC & Third-Party Testing: We provide Material Test Certificates (MTC) with every shipment and welcome third-party inspection.

AI-Powered supplier vetting
SummaryThe supplier is a Shanghai-based limited trading company with 41 employees, focused on fasteners and related metal, mechanical, plastic, rubber, electrical, and photovoltaic products. It offers sample-, design-, and full-customization services, as well as ODM and OEM services, and reports export sales of 71%–90%. In-stock service is available, but there is no overseas warehouse, showroom, agent, or branch. Financial records are identified for 2022–2024, but no financial values or performance conclusions are provided. Service-process evidence is weak: no written corrective/preventive-action or complaint-handling procedures or records are available, while quality-assurance status and fire-drill status are unknown. No certifications, customer cases, or production facilities are explicitly documented.
Supplier typeThe supplier is identified as a limited company and trading company, with 41 employees, no stated parent-group affiliation, and a Shanghai registered and physical address. Its stated product scope centers on fasteners and related industrial products.
After-Sales capabilityThe supplier has in-stock service capacity, but it has no overseas warehouse, showroom, overseas agent, or branch. More importantly, no written corrective/preventive-action procedures or records and no written customer-complaint procedures or records are available, indicating a documented after-sales process is not demonstrated.
R&D capabilityThe supplier lists research and development of metal products and hardware products, and offers ODM services. However, no SDK is available, and the information does not provide measurable R&D resources, patents, or development outcomes; the documented capability is therefore limited but present.
Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, and full customization, together with ODM and OEM services for popular brands. These statements provide direct evidence of broad customization and design-manufacturing service capability.
