Screw cylindrical head - hex DIN 912 M20x45 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 screw has a metric thread M20 and a length of 45 mm, which makes it suitable for applications where high strength and reliability of the connection are required. The material from which it is made is stainless steel grade A4-70, which guarantees high corrosion resistance, which is ideal for use in harsh environments such as the chemical industry, food processing or outdoor applications.

The cylinder head of the screw allows for even pressure distribution on the surface of the material, which is important for minimizing the risk of damage to the parts being joined. The internal hexagon, also known as an inbus, allows for easy and efficient assembly using an Allen key, which increases the accuracy and speed of assembly. The screw is designed to provide high tensile strength, which is indicated by the strength class A4-70. This class means that the minimum tensile strength is 700 MPa, which is suitable for applications with high mechanical loads.

This screw is ideal for use in structures where high strength and corrosion resistance are required, while its standardized dimensions and standards ensure compatibility with various systems and components. The screw is supplied without surface treatment, which is typical of stainless materials that naturally resist corrosion without the need for additional treatment.
