DIN6928 Hexagon Washer Head Tapping Screws

DIN 6928 hexagon washer head tapping screws combine a hexagonal head with an integrated washer flange. The hexagonal head allows the screw to be tightened with a wrench or socket, while the flange spreads the contact load over a wider area than a standard hexagon head. The self-tapping thread forms mating threads in suitable materials, making these screws useful for fastening sheet metal panels, metal housings, brackets, and other components where a wider bearing surface is needed.

As an ISO 9001-certified factory, we use specialized cold heading machines to form the hexagonal heads and washer flanges, followed by thread rolling machines to produce consistent thread profiles. We pay close attention to head dimensions, flange shape, and thread accuracy during production to help ensure a proper fit and consistent fastening performance. Our production process is managed according to the agreed product specifications and quality requirements.

Dimension Chart of DIN6928:

The DIN 6928 dimension chart provides the dimensional references needed to select the correct tapping screw for the thickness and fastening requirements of the assembly. The size range from ST2.9 to ST8 covers different fastening requirements, while the screw length determines the available thread engagement in the receiving material. The hexagon head dimensions and integrated washer diameter are also important when checking tool access and the bearing area beneath the screw head.
