List of screw head drives

The list of screw head drives contains about 125 screw head drives (also called screw profiles), i.e. H. the shapes on the screw head for the attachment of a tool ( screwdriver or wrench ).

Explanations

The list is not complete; it also contains combination profiles. English names are in italics.

In the schemes, depressions in the screw should be drawn in black, elevations in white and the background in gray.

A simple slotted screw then looks like this:
and a hexagon socket screw like this:

Not all schematic drawings in the list conform to this convention.
