Structural screw EN14399-4 (DIN 6914) 10.9 M12x75

Product detailed description

The EN 14399-4 (DIN 6914) structural bolt with dimensions M12 x 75 is designed for high-strength bolted connections of steel structures. This bolt meets the DIN 6914 and EN 14399-4 standards, which ensures its suitability for use in critical applications where high strength and reliability of the joints are required.

The bolt is made of steel of strength class 10.9, which means that it has a minimum yield strength of 900 MPa and a minimum tensile strength of 1000 MPa. These properties make it suitable for use in demanding conditions where high demands are placed on mechanical resistance and stability of the joints.

The screw design includes an enlarged hexagonal head with dimensions of 22 mm in width (B1) and 8 mm in height (H), which allows for effective force transmission and easy handling during assembly. The thread length (L1) is 23 mm, while the total length of the screw is 75 mm. The screw has a metric thread with a pitch of 1.75 mm, which ensures compatibility with common metric nuts and other fasteners.

The surface finish of the screw is without additional treatment, which is suitable for applications where increased corrosion resistance is not required or where additional surface treatment is expected according to specific project requirements. This screw is ideal for use in construction and industrial applications where high strength and reliability of joints are important.
