Hexagon Washer Head Self-Drilling Screws | DIN 7504-K / ISO 15480
Hexagon washer head self-drilling screws are designed for applications where drilling, tapping and fastening can be completed with a single fastener.
The integrated drill point allows the screw to penetrate suitable metal materials during installation, eliminating the need for a separate drilling operation in appropriate applications. The tapping thread then forms the mating thread as the screw advances.
The hexagon washer head provides a strong external hexagonal drive for installation with sockets or nut drivers. The washer-style bearing surface helps distribute the clamping load over a wider area.
DIN 7504-K is commonly associated with hexagon head self-drilling screws with flange, while ISO 15480 specifies the corresponding self-drilling screw design.
These screws are widely used for:
Sheet metal fastening
Metal-to-metal applications
Steel profiles
Roofing and cladding
Metal structures
HVAC equipment
Electrical enclosures
General construction and fabrication
Different diameters, lengths, materials and surface treatments are available according to application requirements.
We also support OEM production, customized packaging and production according to customer drawings or samples.
