Screw cylindrical head - hex DIN 912 M20x140-12.9

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 component is made of steel with strength class 12.9, which guarantees high strength and resistance to mechanical stress. The screw has a metric thread with a diameter of M20 and a pitch of 2.50 mm, while the thread length is 52 mm. The total length of the screw is 140 mm.

The screw head has a cylindrical shape with a diameter of 30 mm and a height of 20 mm, while the internal hexagon allows assembly using an Allen key. The width B1 is 17 mm. The screw has no surface treatment, it is blackened, which can be advantageous in applications where increased corrosion resistance is not required.

This type of screw is suitable for use in industrial applications where high demands are placed on the strength of the connection. Thanks to the internal hexagon, it is possible to achieve a higher tightening torque, which is important for ensuring the reliability and stability of the structure. The screw is ideal for use in mechanical engineering, construction and other technical areas where high strength and precision of the connection are required.
