DIN 7982 defines countersunk head, cross-recessed self-tapping screws with Type C thread-forming geometry. These screws cut their own mating threads into sheet metals and plastics, enabling flush fastening without pre-tapped holes.
DIN 7982 screws have a countersunk head, which sits flush with the surface after installation, making them suitable for applications where a smooth finish is required. DIN 7981 screws, by contrast, have a pan head that remains above the surface.
They are generally made from case-hardened carbon steel for standard sheet-metal use, and stainless steel grades (A2, A4) where higher corrosion resistance or outdoor applications are required.
They are widely used in electrical and electronics assemblies, HVAC ducting, consumer appliances, sheet-metal fabrication, and automotive interiors where flush-mounted fastening is essential.
Common finishes include zinc plating, nickel coating, black oxide, and plain/oiled, each selected based on corrosion resistance, torque control, and aesthetic requirements.
