What Kind of Materials for this Allen bolt Fastener
Steel
Carbon Steel: Carbon steel non - standard cap screws are widely used due to their good strength and relatively low cost. They can have different carbon content levels. Low - carbon steel screws (containing up to about 0.3% carbon) are more ductile and easier to machine. Medium - carbon steel (around 0.3 - 0.6% carbon) provides higher strength and is suitable for applications that require more load - bearing capacity. High - carbon steel (above 0.6% carbon) can be heat - treated to achieve even greater hardness and strength, making them ideal for applications where resistance to wear and high - tensile forces is needed.
Stainless Steel: Stainless steel non - standard cap screws are corrosion - resistant, making them suitable for use in environments where moisture, chemicals, or other corrosive agents are present. The most common types are austenitic stainless steel (such as 304 and 316). 304 stainless steel is excellent for general - purpose applications in mildly corrosive environments like food processing equipment and household appliances. 316 stainless steel, which contains molybdenum, has even better corrosion resistance and is often used in marine environments, chemical plants, and medical equipment.
Aluminum
Aluminum non - standard cap screws are lightweight and have good electrical conductivity. They are used in applications where weight reduction is crucial, such as in the aerospace industry and in some electronics cases. However, aluminum screws have lower strength compared to steel, so they are often used in applications where the fastening forces required are not too high.
Brass
Brass non - standard cap screws have an attractive golden - colored appearance and good corrosion resistance, especially in environments where there is a risk of galvanic corrosion. They are used in decorative applications, such as in furniture and architectural details. Brass also has good machinability, allowing for the production of screws with complex shapes or precise dimensions.
