DIN 7343 coil pins are cylindrical and thin-walled fastening elements designed with flexibility. These pins are engineered to withstand high impact and vibration loads. Their coiled structure allows the pins to expand and flex during installation, providing a secure connection. Typically made from steel, they are coated to enhance corrosion resistance. Coil pins are widely used in machinery, automotive, and various industrial applications.
