Physical properties: Brass is a copper-zinc alloy with a density usually between 8.4 - 8.85g/cm³. Compared with metals such as steel, brass screws are lighter, which makes it possible to reduce the overall weight to a certain extent in some applications that require weight, such as parts of aerospace equipment. Copper has good electrical conductivity, and brass as a copper alloy also inherits this property. Therefore, this screw can be used in electronic equipment where electrical conductivity is required, such as the fixing and connection of circuit boards, to ensure the stable transmission of current.

Thermal conductivity: Brass has good thermal conductivity. When used in some equipment that requires heat dissipation, screws can help transfer heat and play a certain role in heat dissipation. For example, inside a computer case, the use of brass screws helps to dissipate the heat generated by electronic components.

Chemical properties: Brass has excellent corrosion resistance, and a dense oxide film can be formed on its surface. This oxide film can prevent oxygen and moisture from further reacting with the internal metal, thereby improving the corrosion resistance of the screws. In particular, brass screws that have been nickel-plated will have further enhanced corrosion resistance and are suitable for humid or corrosive environments, such as outdoor equipment, ships, etc.

Antioxidation: At room temperature, brass has a certain antioxidant capacity against air and water. However, in an environment containing substances such as sulfur and chlorine, brass may undergo chemical reactions, and discoloration or corrosion may occur on the surface. Therefore, when used in special environments, additional protective measures may be required.

Mechanical properties
Strength and hardness: Brass knurled screws have certain strength and hardness and can withstand certain tension and pressure. However, compared with high-strength steel screws, their strength and hardness are relatively low. Therefore, in some occasions with high strength requirements, such as the fastening of large mechanical equipment, screws of other materials may need to be selected. However, in some scenarios where strength requirements are not particularly high, such as furniture assembly and the fixing of small electrical equipment, brass screws can meet the use

requirements. Brass has good toughness and is not easy to break when subjected to external force. This makes the screws not easy to damage even if they are twisted or deformed during installation and removal, which improves the service life and reliability of the screws.

Processing performance: Brass has good cutting performance and is easy to perform turning, milling, drilling and other processing operations. This allows manufacturers to process screws of various specifications and shapes according to customer needs to meet different usage requirements. For this type of screw with knurled straight lines, brass material can adapt to the knurling process well. Knurling can increase the friction on the surface of the screw, making it convenient for users to manually turn the screws and improve the convenience of operation. Moreover, the surface quality after knurling is better, with clear lines and wear resistance.
