The tamper resistant System Zero dome head security screw has an external non-slip drive built into the head, which helps avoid damage to adjacent components, requiring a special insert bit or key wrench to insert and remove.
Please note that these product properties are not a replacement for the manufacturer's literature and it is always recommended that Fastenright is consulted before specifying.
