Because of this, drives with cruciform slots have taken the put of slots in several purposes. widespread blade, flat-blade, slot-head, flat-idea, or flat-head / flathead screwdriver are all names for the unit utilized to push a slot. much more torque could be specified without having detrimental the screw head having a hollow-floor screwdriver mainly because it is more unlikely to cam out (depart the slot on account of the torque becoming transformed into an axial pressure, comparable to that observed with Phillips travel but relying only on driver blade).
Other screw manufacturers on the 1930s rejected the Phillips concept because it was named for a fairly complicated recessed socket condition in the head with the screw, rather than the simple milled slot of a slotted screw.
