Metric sizes range from M3 to M6, suitable for scenarios where precision connections are required, such as electronic equipment, furniture manufacturing, and automotive parts.
After tempering, alloy steel has high hardness and good toughness, which makes it suitable for repeated disassembly. The corrosion resistance of carbon steel is weaker than that of alloy steel.
Hexagon socket head: Suitable for use with hexagonal wrenches, high torque transmission efficiency, suitable for installation locations with limited space. Hexagon head: Suitable for use with socket wrenches, suitable for metal sheet connections requiring high torque. Self-tapping thread: Full thread: The thread covers the entire screw, providing an even grip and preventing material delamination or cracking.
