Slots in the outer edge of the head provide a more positive drive with less risk of fastener distortion and breakage. Power-driven equipment may be used with the matching driver socket, making this model suitable for mass-production applications where both a high level of security and fast assembly time are required - eg. electronics or office equipment.
