DIN 7971-C self-tapping screws feature a continuous self-tapping thread along the entire shank, designed to form the internal thread directly in the base material during installation. The pointed tip facilitates initial penetration and proper screw alignment, ensuring fast and efficient assembly.
They are suitable for fastening thin sheet metal, light metal materials and plastics. Depending on the thickness and hardness of the base material, pre-drilling can be reduced or, in some cases, eliminated. To achieve optimal performance, it is nevertheless recommended to follow the hole diameters specified by the applicable standards, in order to avoid excessive tightening torque and unwanted stresses in the material.
The thread geometry provides high holding strength, good pull-out resistance and reliable long-term fastening performance.

The cylindrical head ensures uniform load distribution on the fastening surface and allows stable installation, making these screws particularly suitable for technical applications and mechanical assemblies.
The slotted drive allows the use of standard screwdrivers, ensuring ease of installation, accurate tool engagement and reduced risk of head damage during tightening. This configuration is ideal for applications requiring a clean, discreet and functional finish.
DIN 7971 self-tapping screws are manufactured from high-quality materials and are available with various surface treatments, including:
The screw length is measured from the tip to the underside of the head, in accordance with international standards.
Thanks to their versatility and reliability, these screws are widely used in:
They provide an effective solution for fast, precise and durable fastening, reducing installation time and simplifying production processes.
