Phillips self-tapping screw DIN 7981C 4.2x22 galvanized

Product detailed description

The self-tapping Phillips screw according to DIN 7981C, ČSN 021235 and ISO 7049 is designed for applications requiring solid connections without the need for pre-drilling. This screw is made of steel and has a size of 4.2 x 22 mm, which makes it ideal for use in metals and plastics. The surface treatment is made by galvanic zinc plating, which provides protection against corrosion and extends the life of the component.

The screw head is hemispherical, which provides an aesthetic appearance and at the same time allows for even distribution of pressure on the surface of the material. The Phillips cross groove ensures easy and effective assembly using standard tools. The shape of the screw is marked as CH, which means that it has a sharp tip that facilitates penetration into the material without the need for pre-drilling.

This screw belongs to the category of self-tapping screws, which are specially designed to create threads in the materials into which they are inserted. Thanks to its properties, it is suitable for a wide range of applications in industry, construction and home workshops, where a quick and reliable connection is needed without the complications associated with pre-drilling.
