Phillips self-tapping screw DIN 7981C 3.5x6.5 galvanized

Product detailed description

The self-tapping Phillips screw according to DIN 7981C, ČSN 021235 and ISO 7049 is designed for creating solid connections without the need for pre-drilling in metal and plastic materials. This screw has dimensions of 3.5 x 6.5 mm and is made of steel that is galvanically galvanized and passivated, which ensures increased corrosion resistance. Zinc coating is common for applications where protection against oxidation and improvement of aesthetic appearance are required.

Constructively, this screw is equipped with a hemispherical head, which provides uniform pressure distribution on the surface of the material, thereby minimizing the risk of damage. The head is equipped with a Phillips-type cross groove, which allows for effective transmission of torque during assembly and disassembly using appropriate tools, such as cross-head screwdrivers.

The screw belongs to the category of self-tapping screws, which are designed to create their own thread when drilled into the material. This type of screw is ideal for applications in the field of production and assembly, where speed and efficiency of the assembly process are required. Screws of this type are often used in the automotive industry, electrical engineering and in the assembly of sheet metal structures.

Given its technical properties and the standards to which it corresponds, this screw is suitable for a wide range of industrial applications where reliability and durability of joints are required.
