ISO 4762:2004 Socket Head Cap Hex Socket Tapping Screw

ISO 4762:2004 Socket Head Cap Hex Socket Tapping Screw uses a cylindrical head, hex socket drive, and tapping thread. It is suitable for connections requiring compact head geometry, controlled torque application, and assembly without pre-tapping.

The hex socket allows force to be applied in limited spaces, while the regular cylindrical head is suitable for machinery housings, module frames, and precision equipment where appearance and installation stability are important. The tapping thread improves fastening efficiency in sheet metal or light material pilot holes.

This product can be used in automation equipment, electronic enclosures, instrument structures, light machinery, and industrial components. High-strength steel, stainless steel, or treated versions can be selected to meet load, corrosion resistance, and long-term maintenance requirements.
