Metric size coverage: M2, M2.6, M3, M4, M5, M6, a total of 6 specifications, thread diameter range 4-50mm, suitable for electronic equipment, furniture manufacturing, automotive parts and other scenarios that require precision connection.
After tempering, alloy steel has high hardness and good toughness, which is 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.
Fix circuit boards, heat sinks, housings and other components, and adapt to PCB boards
