Screw cylindrical head - hex DIN 912 M12x20 stainless steel A4

Product detailed description

The cylinder head screw with internal hexagon according to DIN 912, ISO 4762 and ČSN 021143 is designed for fixed screw connections with high preload. This particular model has dimensions M12x20 mm, which means that the outer diameter of the thread is 12 mm and the length of the screw is 20 mm. The screw is made of stainless steel grade A4-70, which provides high corrosion resistance, which makes it suitable for use in harsh environments, including the chemical industry and marine environments.

The cylinder head of the screw is designed for use with an Allen key, which allows for efficient torque transmission during assembly and disassembly. The internal hexagon ensures a precise fit of the tool, minimizing the risk of damage to the head when applying high torque. The screw is suitable for applications where it is necessary to achieve high preload in the joint, which increases the strength and stability of the structure.

The strength class A4-70 indicates that the screw has a minimum yield strength of 450 MPa and a minimum tensile strength of 700 MPa. This combination of material properties and mechanical parameters ensures reliability and long service life of the screw even in extreme conditions. The screw is ideal for use in applications where high strength and corrosion resistance are required without the need for additional surface treatment.
