The DIN 7045 standard, published by the German Institute for Standardization (DIN), defines the requirements for H-type or Z-type cross-recessed round-head screws (product class A). This standard was later published by the International Organization for Standardization (ISO) under the title: ISO 7045 H-type or Z-type cross-recessed round-head screws - Product class A. This standard includes the specifications for H-type or Z-type cross-recessed product class A round-head screws with threads from M1,6 to M10.

In the DIN 7045 standard, the requirements for H-type or Z-type cross-recessed round head screws are listed under the following headings:
A versatile type of screw primarily used for metal-to-metal applications are flat-head screws. This screw has a wide head with rounded edges and requires a threaded hole. Ball head screws are often used to fasten metal components such as machinery and automotive parts, and accessories such as license plates and headlights. These screws come in a wide variety of styles, sizes and materials for all types of consumer, commercial and industrial use.
Round head screws are commonly manufactured using stainless steel, carbon steel and alloy steel for better wear and tear. Various coating methods are applied, such as black phosphate for corrosion control and zinc for galvanization.
