ShanghaiKey features
Dual-Standard Square Precision: Manufactured to both DIN557 and DIN562 tolerances, our Square Nuts deliver a consistent flat-face grip and reliable thread engagement across a wide range of application
Stop Mismatched Coating Errors: Our stainless steel square nuts come standard with Plain finish, while carbon and alloy steel versions are always protected with Zinc, Black Oxide, Dacromet, or PTFE
Up to 720 Hours Salt Spray Resistance: Dacromet and PTFE-coated Square Nuts significantly outlast standard fasteners, cutting replacement frequency in half in corrosive or high-vibration environments.
Built for High-Torque Structural Joints: The flat, wide bearing surface resists rotation and spreads load evenly, making our Square Nuts ideal for railway track assemblies, heavy machinery frames
One Supplier, Widest Coverage: Spanning M8-M100-one of the broadest ranges available-across four materials and five coating options, we consolidate what typically requires two or three separate vendor
Material Matched to the Job: Choose Carbon Steel or Alloy Steel for high-strength structural connections, or 304/316 Stainless Steel for corrosion-critical piping and equipment, all from one source
Direct-From-Factory Advantage: As the actual manufacturer-not a trading company-we control every production step, cutting out middleman markups and passing factory-direct pricing to you.
Internationally Certified Production: Our facility holds ISO 9001, BV, ABS, and CE certifications, so every batch of Square Nuts meets recognized international quality standards before it ships.
Full Material Traceability: Every order can be supplied with a Material Test Certificate (MTC), giving you documented proof of chemical composition and mechanical properties for full peace of mind.
Open to Independent Verification: We welcome third-party inspection and testing at any production stage, so you can confirm quality yourself before the shipment ever leaves our factory.

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.
