DIN 7971-F self-tapping screws feature a continuous thread along the entire shank, designed to directly form the mating thread in the base material during installation.
They are suitable for fastening into thin sheet metal, light metal materials, and plastics. Depending on the thickness and hardness of the substrate, they may reduce or eliminate the need for pre-drilling. To ensure optimal performance, it is nevertheless recommended to comply with the hole diameters specified by the relevant standards, avoiding excessive tightening torque and unwanted stresses in the material.
The thread geometry provides high holding power, good pull-out resistance, and reliable long-term fastening performance.

The cylindrical head ensures uniform bearing on the fastening surface and allows stable assembly, making it particularly suitable for technical applications and mechanical assemblies.
The slotted drive allows the use of standard screwdrivers, ensuring ease of installation, accurate engagement, and reduced risk of head damage during tightening. This solution 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 finishes, including:
Screw length is measured from the point 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.
