Screw cylindrical head - hex DIN 912 M20x230-8.8

Product detailed description

The cylinder head screw with internal hexagon, marked according to DIN 912, ISO 4762 and ČSN 021143, is intended for fixed screw connections with high preload. This component is made of steel of strength class 8.8, which means that it has a yield strength of 640 MPa and a minimum tensile strength of 800 MPa. The screw has a metric thread with a diameter of M20 and a length of 230 mm, which makes it suitable for use in applications where a significant length and strength of the connection is required.

The screw head is cylindrical with an internal hexagon, which allows assembly using an Allen key. This type of head is suitable for applications where it is necessary to minimize the height of the head above the surface of the connection. The screw has no surface treatment, it is supplied in black, which is typical for components without additional anti-corrosion protection. Therefore, it is suitable for use in environments where it is not exposed to aggressive corrosive influences.

This screw is ideal for use in mechanical engineering and construction, where high strength and reliability of the connection are required. Thanks to its design and material properties, it is suitable for assembly applications, where it is necessary to achieve high preload and ensure joint stability.
