Produktbeschreibung<\/h2>\n

Die EN 14399-8:2007 Zinc Plated Structural Carbon Steel Hex Bolt<\/strong> is a high-strength fastening component designed for structural steel connections, construction projects, machinery assembly, bridge engineering, steel frames, and heavy-duty industrial applications.<\/p>\n

Manufactured from structural-grade carbon steel<\/strong>, this bolt provides reliable mechanical strength, strong clamping performance, and stable fastening under demanding working conditions. The plain hex head design<\/strong> allows easy installation with standard spanners, sockets, or torque tools, while the partially threaded shank helps improve shear resistance in structural connections.<\/p>\n

Die zinc plated surface finish<\/strong> provides additional protection against rust and oxidation, making the bolt suitable for general industrial, construction, and steel structure applications. For projects requiring strict structural performance, this bolt can be supplied together with matching nuts and washers according to customer drawings, technical specifications, or EN-related requirements.<\/p>\n

    Why Choose EN 14399 Structural Hex Bolts?<\/h2>\n

    EN 14399 series structural bolts are commonly used in steel structure connections where strength, safety, and fastening reliability are important. Compared with ordinary hex bolts, structural bolts are usually used as part of a complete assembly with matching nuts and washers.<\/p>\n

    Die hex head design<\/strong> provides good torque transmission during installation, while the carbon steel body offers strong mechanical performance. The zinc plated finish gives the bolt improved surface protection, making it suitable for many industrial and construction environments.<\/p>\n

    For strict engineering projects, it is recommended to confirm the required standard, bolt grade, nut grade, washer type, thread length, coating thickness, and inspection certificate before ordering.<\/p>\n
