CNC Double-Headed External Hexagon Screw/Customizable Products/Factory Direct/Precision Size Control
Double-Headed External Hexagon Screws / Precision CNC Processing / Customizable The double-headed external hexagon screw is primarily processed through precision CNC machining, utilizing high-precision CNC equipment for cutting, drilling, tapping, and other operations. Each product undergoes a strict process to ensure precision and consistency. CNC machining enables the production of complex thread patterns and shapes, making it suitable for high-precision customization. Material: This product is made from high-strength carbon steel, alloy steel, stainless steel, and other materials to meet different environmental and application requirements. The copper content, hardness, corrosion resistance, and other characteristics of the material can be customized according to customer requirements. Material Grade/Requirements: Based on application needs, material grades include but are not limited to: Carbon Steel (e.g., AISI 1018, 1045) Stainless Steel (e.g., 304, 316) Alloy Steel (e.g., AISI 4140) High-strength Materials (e.g., 16Mn, 45# steel) Surface Treatment: We offer various surface treatments, such as galvanizing, electroplating, oxidation, and phosphating, to enhance the corrosion resistance, wear resistance, and aesthetic appearance of the screws: Galvanizing: Provides corrosion resistance, ideal for outdoor environments. Electroplating: Enhances appearance and corrosion resistance. Oxidation: Suitable for high corrosion resistance requirements. Tolerance Control: The screw size tolerance is controlled within ±0.01mm, and the thread tolerance conforms to ISO standards to ensure high precision.
