EN 14399-8:2007 Perno hexagonal de acero al carbono con zincado, alta resistencia, tuerca hexagonal de cabeza plana

Product Description

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

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

The zinc plated surface finish 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.

Product Specifications

Material and Surface Treatment

This bolt is made from carbon steel, which offers good strength, durability, and cost-effectiveness for structural fastening applications. The zinc plated finish helps protect the steel surface from corrosion during storage, transportation, and normal use.

Note: The product image shows a rough gray metallic surface, which may also look similar to hot dip galvanized finish. If the actual product is ordinary electro zinc plated, the surface will usually appear smoother and brighter.

Product Advantages

Common Applications

The EN 14399-8:2007 zinc plated structural carbon steel hex bolt is widely used in projects that require reliable fastening strength and stable connection performance.

Why Choose EN 14399 Structural Hex Bolts?

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.

The hex head design 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.

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.

Available Custom Options

Matching Nuts and Washers

For structural applications, bolts are usually used together with matching nuts and washers to achieve stable fastening performance.
