DIN7983 Cross Recessed Raised Countersunk Head Tapping Screws

DIN 7983 Cross Recessed Raised Countersunk Head Tapping Screws are designed for assemblies where the fastener head needs to sit neatly within or close to the surface of the component. The raised countersunk head combines a tapered underside with a slightly projecting head, allowing the screw to provide a clean fastening appearance while retaining a defined bearing area around the joint. Its cross recess provides a familiar drive interface for screwdrivers and powered installation tools.

The tapping thread allows the screw to engage directly with a suitable pre-drilled hole, eliminating the need for a separate nut in many sheet-metal and fabricated-component assemblies. The combination of a raised countersunk head, cross recess, and tapping thread makes DIN 7983 useful when both the appearance of the finished surface and practical production assembly matter. Screw diameter, length, material, and surface finish can be selected according to the thickness of the components, substrate characteristics, installation requirements, and service environment.

Dimension Chart of DIN7983 Tapping Screws:

The DIN 7983 dimension chart covers the main dimensions used to select a raised countersunk head tapping screw for a particular joint. The available tapping screw sizes range from ST2.2 to ST6.3, providing options for thin sheet-metal components as well as larger fabricated parts. Screw diameter and length should be selected according to the material thickness and the required thread engagement, while the head dimensions determine how the screw seats against the countersunk surface.
