Screw cylindrical head - hex DIN 912 M12x320-10.9

Product detailed description

The cylinder head screw with internal hexagon according to DIN 912, ISO 4762 and ČSN 021143 is designed for applications requiring strong screw connections with high preload. This particular model has a metric thread with a diameter of M12 and a length of 320 mm, while the thread length is 36 mm. The screw is made of steel with a strength class of 10.9, which means that it has a high tensile strength, namely a minimum yield strength of 900 MPa and a minimum tensile strength of 1000 MPa.

The screw head has a cylindrical shape with a diameter of 18 mm and a height of 12 mm, while the internal hexagon allows assembly using an Allen key. The width of the internal hexagon is 10 mm. The screw has no surface treatment, which is important to consider when using it in corrosive environments where additional protection might be needed. The thread pitch is 1.75 mm, which is standard for this type of metric thread.

This screw is suitable for use in mechanical engineering and construction, where it is necessary to ensure high strength and reliability of the connection. Thanks to its design and material properties, it is ideal for applications where high demands are placed on mechanical resistance and assembly accuracy.
