Key features

Designed according to the DIN 7504 K specification, providing a standardized self-drilling fastening solution for metal sheet and industrial applications.

The hexagonal head allows secure engagement with compatible sockets or drivers, while the integrated washer provides a larger bearing surface for stable fastening.

The sharp drill point is designed to penetrate suitable metal sheets efficiently, helping reduce the need for separate pilot drilling during installation.

Multiple stainless steel grades are available to meet different requirements for corrosion resistance, mechanical strength, durability, and service environments.

304, 316, and 316L stainless steel provide good corrosion resistance and are suitable for various indoor and outdoor fastening environments.

410 stainless steel offers higher hardness and mechanical strength, making it suitable for applications requiring greater strength and wear resistance.

The combination of a self-drilling point and hex washer head enables fast and stable fastening of suitable sheet metal and metal components.

Suitable for sheet metal fabrication, machinery, construction, equipment assembly, HVAC systems, electrical enclosures, and other industrial fastening applications.
