Phillips self-tapping screw DIN 7981C 3.9x25 galvanized

Product detailed description

The self-tapping screw with a Phillips cross recess according to DIN 7981C, ČSN 021235 and ISO 7049 is designed for fixed connections in sheet metal and plastics without the need for pre-drilling. This screw has dimensions of 3.9 mm in diameter and 25 mm in length, which makes it suitable for a wide range of applications in metal and plastic materials.

The screw is structurally equipped with a hemispherical head, 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 recess ensures easy and effective tightening using a standard cross screwdriver, which reduces the risk of damage to the head during assembly.

The screw is made of steel, which is galvanically galvanized and passivated, which increases its resistance to corrosion. This surface treatment guarantees long-term service life even in more demanding conditions. The screw belongs to the group of self-tapping screws, which are designed to create threads in the materials into which they are inserted, eliminating the need for pre-drilling.

The screw is an ideal solution for applications where it is necessary to ensure a strong and reliable connection in thin-walled materials such as sheet metal and plastics. Its use is wide, from industrial applications to home projects where quick and efficient assembly is required.
