DIN 7983 Raised Countersunk Head Self-Tapping Screws

DIN 7983 Raised Countersunk Head Self-Tapping Screws are self-tapping screws with a raised countersunk, also known as oval countersunk, head and a cross recess. The raised head provides a finished appearance while the countersunk underside allows the screw to seat neatly against the fastening surface. DIN 7983 is a widely recognized legacy designation, while ISO 7051 is the current international standard for cross-recessed raised countersunk head tapping screws.

These screws are commonly used for fastening sheet metal, thin metal components, panels, electrical enclosures, appliances, equipment housings and other assemblies where a raised countersunk head is preferred. The self-tapping thread is designed to form or engage threads in suitable pre-drilled or prepared materials, making the screws suitable for a wide range of general industrial fastening applications.

DIN 7983 Raised Countersunk Head Self-Tapping Screws are available with different cross-recess configurations, including Phillips and Pozidriv types, depending on the required drive system. Point and thread configurations can also vary according to the application and material being fastened.

Common sizes are available across the ST2.2 to ST9.5 range under the current ISO 7051 scope, with steel and stainless steel options widely used in commercial applications. When sourcing these screws, buyers should specify the required thread size, length, material, drive type, surface finish and applicable standard to ensure dimensional and functional compatibility.
