Screw cylindrical head - groove DIN 84 M4x8 brass

Product detailed description

The screw with a cylindrical head and a continuous groove according to DIN 84, ISO 1207 and ČSN 021131 is made of brass, which guarantees excellent corrosion resistance and good electrical conductivity. This component is ideal for precision assemblies in mechanical and electrical engineering, where a clean and solid connection is required.

The screw has a metric thread with a diameter of M4 and a length of 8 mm, while the thread pitch is 0.70 mm. The cylindrical head has a diameter of 7 mm and a height of 2.6 mm, which provides sufficient surface area for applying torque using a tool with a straight groove. The groove width is 1.2 mm, which allows easy handling during assembly and disassembly.

The brass material without surface treatment guarantees natural protection against oxidation, which is advantageous in environments with lower demands on chemical resistance. The screw is suitable for applications where reliability and aesthetic appearance of the connections are important. It is used especially where it is necessary to ensure a firm and stable connection of components, such as electrical equipment, precision mechanics and other technical applications.
