①, When L＜L ref., e=0, and the method of diameter ds is omitted

②, Material:

a) Steel, strength class (material): St, standard DIN EN 10087, DIN EN 10277-3 (these two material standards have been replaced by DIN EN ISO 683-4)

b) Stainless steel, strength class (material): A1, A2 according to standard DIN EN ISO 3506-1

c) Non-ferrous metals, strength class (material): CU3 according to standard DIN EN 28839

Differences between stainless steel screws and regular screws:

1. Stainless steel screws have higher strength than regular screws due to the addition of relatively more alloying elements, allowing them to withstand greater shear forces.

2. Stainless steel screws are resistant to rust and corrosion, while regular screws are more prone to rusting and degradation, leading to a shorter lifespan of the components.

Stainless steel screws have higher strength and toughness compared to regular screws, and they are relatively more expensive.

Selection criteria for stainless steel screws:

stainless steel screws are primarily used in environmental equipment, medical devices, communication equipment, power facilities, electronic products, instruments, food machinery, the petrochemical industry, ship assembly, pump and valve pipelines, building facades, outdoor environments, sports facilities, and outdoor decorations.

Principles for selecting stainless steel screw materials:

1. Consider the mechanical properties, especially strength 2. Requirements, of the stainless steel screw material.

3. Consider the corrosion resistance requirements of the material based on the working conditions.

4. Consider the heat resistance properties (high-temperature strength, 5. oxidation resistance) of the material based on the working temperature.

Consider the processing properties of the material based on the production process requirements.
