Screw cylindrical head - Allen DIN 912 M20x200-10.9

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 10.9, which means that it has a high tensile strength, namely at least 1040 MPa, and is suitable for applications where high resistance to mechanical stress is required. 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 200 mm.

The cylinder head of the screw has a diameter of 30 mm and a height of 20 mm, which provides sufficient surface area for applying torque using an Allen key, which is inserted into the internal hexagon with a dimension of 17 mm. This design allows for efficient torque transmission and minimizes the risk of head damage during assembly.

The screw is supplied without surface treatment, which is suitable for applications where increased corrosion resistance is not required, or where subsequent surface treatment is planned according to specific project requirements. This screw is ideal for use in engineering, construction and other industries where it is necessary to ensure a reliable and strong connection of components.
