Screw cylindrical head - hex DIN 912 M4x55-10.9

Product detailed description

The cylinder head screw with internal hexagon according to DIN 912, ISO 4762 and ČSN 021143 is made of steel with strength class 10.9. This component is designed for fixed screw connections with high preload, which means that it is able to withstand high mechanical loads. The screw is suitable for assembly using an Allen key, which allows for efficient and precise tightening.

The screw has a metric thread with a diameter of M4 and a pitch of 0.70 mm. The total length of the screw is 55 mm, while the thread length is 20 mm. The cylinder head has a diameter of 7 mm and a height of 4 mm, while the width for the Allen key is 3 mm. These dimensions guarantee compatibility with common assembly applications where precision and reliability are required.

The material of the screw is uncoated steel, which means that it is necessary to consider its use in an environment where it may be exposed to corrosion. The strength class 10.9 indicates that the screw has a minimum yield strength of 900 MPa and a minimum tensile strength of 1000 MPa, which makes it suitable for use in demanding conditions where high mechanical properties are required.

This screw is ideal for applications where high strength and precision are required, such as in mechanical engineering, the automotive industry or in plant construction, where the emphasis is on reliability and durability of joints.
