A cheese-head slotted drive machine screws, defined in the DIN 84 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 cheese head machine screws are fully threaded and can be used for many applications.

The requirements for slotted cheese head machine screws are listed in the DIN 84 standard under the following headings:
Similarly, the ISO 1207 standard published by the International Standards Organization (ISO) describes the properties of slotted cheese head screws with product class A and threads from M1,6 to M10 (ISO 1207 Slotted cheese 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 cheese head machine screws are slotted cylindrical head threaded fasteners driven by a flat head screwdriver. The outer diameter of the metric cheese head machine screw is smaller than that of the pan head machine screw. But the thickness is greater than a pan head allowing a deeper slot for a screwdriver. These screws are produced from steel, stainless and brass.
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, within the scope of DIN 84 standard, for slotted cheese head machine screws, within the scope of ISO 1207 standard, slotted cheese head screws. (product class A) and within the scope of the BS 4183 standard, it also provides testing services for machine screws and machine screw nuts.
