Slotted Cylindrical Head Bolts

Carbon steel is a common material for Slotted Cheese Head Industrial Screws. It offers good tensile strength and hardness, enabling the bolts to withstand significant mechanical stress and resist deformation and breakage during use. Carbon steel bolts are relatively inexpensive, making them a cost-effective choice for many applications. However, they are susceptible to rust in humid or corrosive environments. To address this, they often undergo surface treatments such as zinc plating or galvanizing to enhance corrosion resistance.

Stainless steel, such as grades 304 and 316, is widely used for Notched Cheese Top Head Screws due to its exceptional corrosion resistance. Stainless steel can withstand oxidation and corrosion in harsh environments like marine, chemical, and humid settings, ensuring long-term reliable connections. It also exhibits good heat resistance, maintaining its mechanical properties at high temperatures. Additionally, stainless steel offers excellent weldability and machinability, allowing for the production of high-quality bolts with precise dimensions and smooth surfaces.

Slotted Cheese-shaped Head Threaded Screws made from alloy steel are designed for high-strength fastening requirements. Alloy steel contains elements like chromium, molybdenum, and vanadium, which enhance its strength, toughness, and hardenability. These bolts exhibit superior mechanical properties and can meet the demands of heavy-duty applications in industrial machinery, automotive, and other sectors. They provide reliable fastening in scenarios involving high stress, impact, and vibration.

To further improve performance, Grooved Cheese Head Construction Screws often undergo various surface treatments. Zinc plating is a common process that coats the bolt surface with a layer of zinc, protecting it from rust and corrosion. Passivation treatment forms a dense oxide film on the surface, enhancing corrosion resistance and oxidation resistance. Black oxide treatment gives the bolt a black oxide coating, improving wear resistance and heat resistance while providing an aesthetically pleasing appearance. These treatments extend the service life of the bolts and enhance their adaptability to different environments.
