Screw cylindrical head - groove DIN 84 M4x25 galvanized

Product detailed description

The screw with a cylindrical head and a slot according to DIN 84, ISO 1207 and ČSN 021131 is intended for precision assemblies in mechanical engineering and electrical engineering, where a clean and solid connection is required. This screw has a metric thread with a diameter of M4 and a length of 25 mm, with a thread pitch of 0.70 mm. The screw head has a cylindrical shape with a diameter of 7 mm and a height of 2.6 mm, with a slot width of 1.2 mm. The slot is continuous, which allows easy tightening and loosening using a standard flat screwdriver.

The screw material is steel with a strength class of 4.8, which means that it has a yield strength of 320 MPa and a tensile strength of 400 MPa. The surface treatment is white zinc plating, which provides protection against corrosion and increases resistance to external influences. This surface treatment is suitable for applications where increased resistance to corrosive conditions is required.

The screw is ideal for use in applications where it is necessary to ensure a strong and reliable connection, while its design features allow for easy handling and assembly. It is suitable for a wide range of industrial applications, including the production of machinery, equipment and electrical components.
