When searching for a DIN 7504 K standard PDF, you will often find references to .ISO 15480 is the modern international equivalent. While they are highly interchangeable, slight differences exist in head dimensions and standard testing tolerances. Always check your project specifications to confirm if the legacy DIN standard or the newer ISO standard is mandatory.
The defining feature of the DIN 7504 K screw is its thread geometry, which differs significantly from standard metric screws (DIN ISO 261/262) or sheet metal screws (DIN 7971). Key geometric parameters include:
Carbon steel screws require surface treatments to prevent oxidation:
Offers excellent general corrosion resistance for outdoor infrastructure.
If you're looking for a for these specifications, I can help you find a technical data sheet .g., A2 stainless) or load data ? DIN 7504 K ~ISO 15480 560 HV - Tme.eu din 7504 k standard pdf
The standard specifies requirements for self-drilling tapping screws featuring a hexagon head with a flange (collar) . This specialized fastener is designed to drill its own pilot hole, tap its own thread, and secure the connection in a single operation, primarily in metal-to-metal applications. Key Technical Specifications
Reduces the number of tools and steps required (no need for separate drill bits or taps).
(Note: The above is a summary. The official PDF contains full tolerance classes.)
The standard specifies the requirements for self-drilling screws with a hexagonal head and a tapping screw thread . This standard is crucial for ensuring that these fasteners can drill their own pilot holes in a single operation, typically in metal applications. When searching for a DIN 7504 K standard
The DIN 7504 K standard specifically focuses on the requirements for screw and bolt fasteners used in various applications, including construction, automotive, and industrial equipment. The standard covers a range of topics, including:
Hex head for high torque application, integrated flange for increased bearing surface, and a self-drilling point designed to penetrate metal. 2. Technical Specifications and Dimensions
Assembling ductwork, ventilation systems, and heating units.
The standard specifies a case-hardened hardness of 560 HV (Vickers Pyramid Number) or higher. The defining feature of the DIN 7504 K
This is the most critical variable. The standard recommends specific hole diameters for different materials.
The DIN 7504 K standard specifies the following requirements for bolted connections:
The standard (often referenced alongside the equivalent ISO 15480 standard) specifies the requirements for hexagon head self-drilling screws with a collar (or press washer).
