The core advantages of 304 stainless steel large flat-head self-tapping screws are "corrosion resistance and rust prevention, material protection and stability, aesthetic appearance when exposed, and convenient installation."
Made of 304 stainless steel, this material is corrosion-resistant and rust-proof in all scenarios, featuring an alloy ratio of 18% chromium and 8% nickel. A dense oxide film forms on its surface, which can withstand moisture, salt spray (not high concentrations from coastal areas), mild acids and alkalis, and daily cleaning agents. It remains rust-free and corrosion-resistant even after long-term use in kitchens, bathrooms, balconies, outdoor rain shelters, and other scenarios. There is no risk of plating peeling off, avoiding the rusting issue that occurs when the plating of carbon steel nickel-plated screws falls off. Its service life is 4-6 times longer than that of carbon steel models.
The large flat head with wide contact design, featuring both excellent protection and anti-loosening properties, boasts a head diameter 2-3 times larger than that of ordinary round head screws. This design provides a large contact area with the workpiece, maximizing pressure distribution during tightening and preventing screws from embedding into soft/thin substrates such as wood, plastic, and thin metal (preventing cracking, indentation, and perforation). The wide contact surface enhances friction with the workpiece, offering superior anti-loosening performance compared to small head screws in scenarios like equipment vibration and daily furniture use, making it especially suitable for exposed fastening applications.
Self-tapping threads, equipped with efficient pre-treatment-free and self-sharpening cutting threads, allow direct drilling into substrates such as wood, eco-boards, engineering plastics, and thin steel plates (≤1.2mm) without the need for pre-drilling or tapping. Both manual screwdrivers and electric screwdrivers can be used, significantly saving assembly time. No nut is required, allowing for installation by a single person, making it suitable for factory mass production, on-site decoration and construction, or personal DIY scenarios.
