on the other hand, because an influence driver commonly eludes the slot during installation, harmful the screw and the material all-around it, this design will not be recommended to be used with energy equipment. for this reason, drives with cruciform slots have taken the place of slots in several programs. typical blade, flat-blade, slot-head, flat-tip, or flat-head / flathead screwdriver are all names for your product used to generate a slot. extra torque may be specified with out damaging the screw head that has a hollow-ground screwdriver because it is not as likely to cam out (leave the slot because of the torque currently being converted into an axial drive, just like that seen with Phillips push but dependent only on driver blade).

Phillips screw heads Possess a cross-formed indentation on the top with the screw, requiring a Phillips screwdriver.

Pozidriv and Phillips seem to be largely interchangeable, however, if taken improperly, they may be hazardous. When tightened, pozidriv screwdrivers may perhaps slide or pull off the Phillips screw head even though they'd jam suit into Phillips screws.
