The core advantages of 304 stainless steel cross-belt screws are "material protection against loosening, corrosion resistance and rust prevention, convenient installation, and aesthetic and tidy appearance."

1. Comes with a built-in washer (spacer), integrating both protection and anti-loosening functions. The washer is integrally molded beneath the screw head, eliminating the need for additional flat washers. This allows for a one-step installation, saving time on accessory procurement and assembly.
   Protecting the base material: The washer increases the contact area between the screw and the workpiece, evenly distributing the tightening pressure, preventing the screw from embedding into soft/thin-walled base materials such as wood, plastic, and thin metal, and avoiding cracking, deformation, or indentation of the base material. Enhancing anti-loosening: The anti-slip surface of the washer fits tightly with the workpiece, coupled with the biting action of the thread, improving the vibration resistance. Under working conditions such as home appliance operation and daily furniture use, it is less prone to loosening, and its anti-loosening effect is superior to that of ordinary non-interference screws.
2. 304 stainless steel material, featuring multi-scenario corrosion and rust resistance with an alloy ratio of 18% chromium and 8% nickel, forms a dense oxide film on the surface, which can withstand the erosion of humid, salt spray (non-coastal high concentration), mild acid and alkali environments. It remains rust-free and corrosion-resistant after long-term use in kitchen, bathroom, balcony, outdoor rain-proof equipment, and other scenarios; there is no risk of plating peeling off, avoiding contamination of workpieces caused by the peeling of carbon steel screw plating. Its service life is 4-6 times that of carbon steel galvanized models. The material is non-magnetic, environmentally friendly, and non-toxic, suitable for use in scenarios requiring safety, such as children's products and food machinery parts.
3. Cross recess drive, versatile, convenient, and easy to operate. The cross recess is a versatile drive slot type, compatible with ordinary screwdrivers and electric screwdrivers, with precise positioning, making it difficult for the screwdriver to slip during disassembly and assembly, and even novices can easily get started. Compared to specialized slot types such as hexagonal, it requires no additional specialized tools, making it suitable for home DIY, on-site quick repairs, and other scenarios.
