DIN 965 Cross Countersunk (Phillips) Flat Head Machine Screws - ISO 7046 H Type or Z Type Cross Recessed Countersunk Flat Head Screws (Common Head Style), Product Class A

The metric cross countersunk (Phillips) flat countersunk head machine screws as defined in the DIN 965 standard published by the German Institute for Standardization (DIN) are designed for metal-to-metal applications that require a pre-drilled hole and a matching metric nut or screw to be screwed in. These screws are usually fully threaded with machine threads and a blind spot. Recommended pre-drilled hole sizes vary depending on the diameter of the screw to be used, but should be slightly larger in diameter than the main (maximum) thread diameter. These screws are manufactured from zinc plated steel and stainless steel. Metric flat countersunk heads have a flat top surface and a cone-shaped bearing surface with a head angle of approximately 90 degrees. Used for applications where the head must be flush with the mating surface of the substrate. Cross countersunk head machine screws are produced in diameters from M1.6 to M10, in zinc-plated steel and stainless steel, and up to 38 mm long.

Similarly, in the ISO 7046 standard published by the International Standards Organization (ISO), the characteristics of countersunk flat head screws with product class A and property class 4.8 and with H-type or Z-type cross-recessed threads from M1,6 to M10 are described.

Another standard in this regard is the following standard published by the British Standards Institute (BSI): BS 3692 ISO Metric precision hex bolts, screws and nuts, specification.
