Cross Recessed Pan Head SEMS Screw
The pan head three-piece screw is a precision fastener that combines functionality and convenience. Its head features a rounded head design, facilitating quick tightening and loosening with a screwdriver. Its unique feature is the integrated spring washer and flat washer; this combination effectively enhances the screw's anti-loosening performance, maintaining a good tightening effect even under vibration. The flat washer also increases the force-bearing area, preventing damage to the surface of the connected parts. The shank has a standard metric mechanical thread with a flat end, ensuring high thread precision and a tight fit for stable connection. Common sizes range from M2 to M8, with a wide range of materials available, including 304 stainless steel, 316 stainless steel, low-carbon steel, and medium-carbon steel, allowing for flexible selection based on different usage environments and strength requirements. Various surface treatments are also available, such as natural stainless steel, stainless steel passivation, environmentally friendly blue-white zinc plating, color zinc plating, and environmentally friendly nickel plating, which not only improve the product's corrosion resistance and aesthetics but also meet environmental requirements in different scenarios. It is widely applicable to various occasions such as electronic equipment assembly, home appliance fixing, communication equipment assembly, sheet metal connection, and precision instrument fastening, providing a reliable guarantee for the stable connection of various devices.
