Import Din 6914 Structural Bolt — Buy in wholesale FOB from Supplier in China

The Din 6914 structural bolt is a high-strength fastener designed for load-bearing connections in steel structures, manufactured to DIN 6914 and ISO standards. This listing specifies available grades 8.8, 10.9, and 12.9, with material options including carbon steel, alloy steel, and stainless steel. Surface finishes include plain, zinc-plated, and black oxide, each selected for corrosion resistance or aesthetic compatibility in industrial environments. Dimensions and thread profiles follow exact DIN 6914 specifications for head geometry, shank length, and thread pitch.

These bolts are typically produced from medium-carbon alloy steel for grades 10.9 and 12.9, heat-treated to achieve tensile strengths of 1040 MPa and 1220 MPa respectively. Stainless steel variants use AISI 304 or 316, offering corrosion resistance in humid or coastal applications. The plain finish is standard for painted or coated assemblies, while zinc plating provides sacrificial protection. Black oxide is applied for minimal friction and moderate rust inhibition in dry indoor settings.

Buyers in construction, bridge fabrication, and heavy machinery sectors source these bolts for structural joints requiring high preload and fatigue resistance. They are commonly used with matching Din 6915 Hv10 nuts and hardened washers. Packaging is in cartons or plastic bags on pallets, with monthly supply capacity at 100,000 pieces. Trade terms are T/T, and shipments originate from Shanghai or Ningbo ports. Buyers should confirm grade certification and batch traceability before ordering.

Ningbo Steel Bolt Co., Ltd operates from Panjiashan, Xiepu Town, Zhenhai District in Ningbo, Zhejiang Province, China. The company specializes in manufacturing structural fasteners for industrial applications, with production focused on DIN and ISO-compliant bolts and related hardware. The supplier’s trust tier is harbor, indicating verified business registration and factory location, though response rate and average response time are not available on the listing.

No claims are made regarding years in operation, employee count, or client names. The supplier does not advertise certifications such as ISO 9001 or third-party testing reports. Buyers should request material test certificates and batch records directly. The listing confirms capacity at 100,000 pieces per month and availability of multiple finishes, but does not specify whether the facility is vertically integrated or sources raw materials externally.
