Screw cylindrical head - hex DIN 912 M3x35-8.8 galvanized

Product detailed description

The cylinder head screw with internal hexagon according to DIN 912, ISO 4762 and ČSN 021143 is intended for fixed screw connections with high preload. This screw is made of steel of strength class 8.8, which means that it has a minimum yield strength of 640 MPa and a minimum tensile strength of 800 MPa. These properties make it suitable for use in applications where high mechanical resistance and reliability of connections are required.

The screw has a metric M3 thread with a nominal diameter of 3 mm and a thread pitch of 0.50 mm. The thread length is 18 mm, which allows sufficient insertion into the nut or threaded hole to ensure a fixed connection. The total length of the screw is 35 mm. The cylindrical head has a diameter of 5.5 mm and a height of 3 mm, while the internal hexagon (hexagon) has a width of 2.5 mm, which allows assembly using an Allen key.

The surface treatment of the screw is white zinc-plated, which provides increased corrosion resistance and improves the aesthetic appearance. This treatment is suitable for applications where the screw is exposed to moisture or other corrosive influences.

The screw is ideal for use in mechanical engineering, the automotive industry and other technical sectors where it is necessary to ensure a strong and reliable connection of components. Thanks to its properties and standardized dimensions, it is compatible with other components and systems that meet the same standards.
