304 stainless steel flat head self-tapping screws CA ultra-thin cross large flat head self-tapping screws M2M3M4M5

The core advantages of 304 stainless steel flat-head Phillips self-tapping screws are "material protection and anti-loosening, corrosion and rust resistance, aesthetic appearance when exposed, and convenient installation",

1. The design features a large flat head with a wide contact area, providing both excellent protection and anti-loosening performance. The head diameter is 30%-50% larger than that of ordinary round head self-tapping screws, ensuring a larger contact area with the workpiece. When tightened, it can evenly distribute pressure, preventing the screw from embedding into soft/thin-walled substrates such as wood, plastic, and thin metal, thus preventing substrate cracking, deformation, or indentation. The wide contact surface significantly increases friction, making it suitable for working conditions such as strong outdoor winds, home appliance vibrations, and daily furniture use. Its anti-loosening effect far exceeds that of small-head screws, making it particularly suitable for exposed fastening scenarios.
2. Cross recess + self-tapping thread, efficient installation without pre-treatment. Cross recess drive: precise positioning, high fit with screwdrivers/electric screwdrivers, easy to operate even for novices without slipping during disassembly and assembly; self-tapping thread: comes with sharp cutting threads, no need for pre-drilling or tapping, can be directly drilled into wood, eco-board, engineering plastic, thin steel sheet (≤1.2mm) and other substrates, allowing for installation by one person, significantly saving assembly time, suitable for factory mass production, on-site decoration, or DIY maintenance.
3. The exposed and aesthetically pleasing design features a flat head with a large, flat surface that is safe and scratch-resistant. After tightening, it fits more closely to the surface of the workpiece, creating a visually flat and clean appearance. The edges of the head are chamfered smoothly, eliminating sharp corners, ensuring that daily contact will not scratch skin, clothing, or equipment parts. It is suitable for exposed installation scenarios (such as outdoor fences, door and window frames, decorative panels)
