304 stainless steel cylindrical head hexagon socket self-tapping screws, self-tapping wood screws, hexagon socket nails, M4, M5/M6 bolts

The core advantages of 304 stainless steel cylindrical head hexagon socket self-tapping screws are "high torque drive, corrosion resistance and rust prevention, fastening stability, and precision adaptability to various scenarios."

1. Hexagonal drive, high torque transmission + anti-slip design. The hexagonal slot pattern fits the wrench with a high degree of precision, achieving over 90% fit, enabling efficient transmission of high torque. Compared to Phillips and slotted screws, it is less prone to slipping during disassembly and assembly (due to wear and slippage of the slot), making it particularly suitable for precision assembly scenarios that require precise control of tightening force (such as internal fixation of electronic devices and installation of mold accessories). In confined spaces, it is easy to apply force with an extended hexagonal wrench, providing operational flexibility far exceeding that of ordinary slot screws.
2. 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 (non-coastal high concentration), and mild acid and alkali environmental erosion. It remains rust-free and corrosion-resistant even after long-term use in kitchen, bathroom, 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. 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. Its service life is 4-6 times that of carbon steel galvanized models.
3. Cylindrical head structure, uniform stress distribution + non-interference components. The cylindrical head features a uniform diameter cylindrical design, with a low head height and flat sides. After tightening, it does not protrude excessively and does not interfere with the moving parts inside the equipment (such as sliders, gears, circuit boards), making it suitable for securing internal components of precision equipment chassis and home appliances. The contact between the head end face and the workpiece is a flat fit, with evenly distributed pressure, avoiding excessive local pressure that could damage thin plates or plastic parts.
