Self-tapping screw phillips DIN 7516D M4x40 galvanized

Product detailed description

The countersunk head Phillips cross recess self-tapping screw according to DIN 7516D is designed for creating threads in sheet metal and non-ferrous metals. This type of screw is made of galvanized steel, which ensures its increased corrosion resistance and longer service life compared to non-galvanized variants. Galvanizing is a process in which a layer of zinc is applied to the surface of the steel, which acts as a protective barrier against corrosive influences.

The screw has a metric M4 thread and a length of 40 mm, which makes it suitable for applications where precise and strong fixation is required. The countersunk head allows the screw to be flush with the material, achieving a smooth surface without protruding parts. The Phillips cross recess is designed to provide optimal torque transmission during assembly, reducing the risk of damage to the screw head or tool.

DIN 7516D specifies the technical requirements for this type of self-tapping screws, including dimensional tolerances and mechanical properties. Screws according to this standard are ideal for use in industrial applications where reliable and efficient assembly into thin-walled materials is required. Due to their properties, these screws are widely used in the automotive, electrical and mechanical engineering industries.
