The cross-section of the screw part is shaped like a rice ball (triangular), allowing for fastening with a smaller torque compared to tapping screws. It can be used with both metal sheets and plastic components. It enables standardization and integration of screws during assembly manufacturing. It is compliant with EU-RoHS regulations.
