Structural screw EN14399-4 (DIN 6914) 10.9 TNZ M12x85

Product detailed description

Structural bolt EN14399-4 (DIN 6914) 10.9 TNZ M12x85 is designed for strength and dynamically stressed connections in steel structures. This component is made of steel with a strength class of 10.9, which means that it has a minimum yield strength of 900 MPa and a minimum tensile strength of 1000 MPa. Such mechanical properties guarantee high resistance to mechanical stress and are suitable for critical applications where high reliability of connections is required.

The bolt has a metric thread with a diameter of M12 and a pitch of 1.75 mm. The total length of the bolt is 85 mm, while the thread length (L1) is 23 mm. The bolt head is hexagonal with a width of 22 mm and a height of 8 mm, which allows the use of standard tools for assembly and disassembly. The raised hexagonal head provides better force distribution and increases the stability of the connection.

The surface treatment of the screw is hot-dip galvanizing, which ensures high corrosion resistance and extends the service life of the component even in harsh outdoor conditions. The EN14399-4 (DIN 6914) standard guarantees that the screw meets all quality and safety requirements for use in steel structures, where high demands are placed on the reliability and durability of joints.
