Hex heads are characterised by their hexagonal shape, made to be driven by a wrench or socket. This design and style allows for superior torque software, building them a go-to option for large-duty mechanical applications.

The Pozidriv screw drive as well as Supadriv screw generate are rather equivalent with regard to how they work and look. This is a subsequent development by the identical business.
