A pan head slotted drive machine screws, defined in the DIN 85 standard published by the German Institute for Standardization (DIN), are externally threaded fasteners designed to be combined with threaded nuts or threaded holes in parts designed to hold them together. Slotted pan head machine screws are fully threaded and can be used for many applications.

The requirements for slotted pan head machine screws are listed in the DIN 85 standard under the following headings:
Similarly, in the ISO 1580 standard published by the International Standards Organization (ISO), the characteristics of slotted round head screws with product class A and threads from M1,6 to M10 are described (ISO 1580 Slotted round head screws - Product class A).
Another standard published on this subject is BS 4183, published by the British Standards Institute (BSI). This standard describes the requirements for metric countersunk machine screws.
Slotted pan head machine screws are threaded fasteners with a flat bottom and a round head on top. Metric slotted round head machine screws have a slot for a flat-tipped screwdriver. The outer diameter of the head on a pan head machine screw is approximately twice the diameter of the thread size. Metric pan heads are the most commonly used type of machine screw.
Among the numerous test, measurement, analysis and evaluation studies it has given for businesses in various sectors, our organization, with its trained and expert staff and advanced technological equipment, provides slotted round head screws for slotted pan head machine screws within the scope of DIN 85 standard, within the scope of ISO 1580 standard. (product class A) and within the scope of the BS 4183 standard, it also provides testing services for machine screws and machine screw nuts.
