EN 14399 / DIN 6914 High Strength Hex Bolts, automotive fastener

Our EN 14399 / DIN 6914 High Strength Hexagon Structural Bolts are engineered for critical load-bearing connections requiring ultimate reliability and safety:

Key Advantages for Your Applications:

• Exceptional Load Capacity: Specifically designed for high-strength structural applications, capable of withstanding significant tensile and shear loads without deformation or failure.

• Ensured Structural Integrity: Provides a robust and durable connection essential for the reliability and safety of critical structures and heavy-duty systems.

• Precision and Consistency: Manufactured to stringent EN14399 and DIN6914 standards, ensuring precise dimensions and consistent performance for reliable assembly.

• Durability Against Elements: Available with various finishes (ZINC, ZINC PLATED, Black) offering enhanced corrosion resistance, prolonging lifespan in challenging environments.

• Versatile Structural Solutions: Offered in a wide range of sizes (including customized options) to meet the diverse requirements of various structural designs and connection points.

• Long-Term Value: Their high strength and durability minimize maintenance and replacement costs, providing a cost-effective solution over the operational life of the assembly.

Ideal for:

• Heavy Vehicle Frame Assembly: Securing primary frame components, crossmembers, and critical load-bearing chassis elements in trucks, buses, and specialized vehicles.

• Suspension and Axle Structures: Providing essential strength and reliability for connecting suspension systems and heavy-duty axles to vehicle frames.

• Trailer Manufacturing: Utilized in the assembly of trailer frames, hitches, and kingpin connections requiring maximum structural integrity.

• Vehicle-Mounted Equipment: Fastening structural mounts and supports for cranes, excavators, and other heavy machinery integrated onto vehicle chassis.

• Bridge and Infrastructure Connections: While broader, fundamental for highly stressed structural joints in bridges and civil engineering elements related to transportation routes.

• Railcar Construction: Used in the structural assembly of railcars and components subject to heavy loads and dynamic forces.
