Abstract: A screw head and screwdriver for use in combination are provided to reduce the occurrence of stripping a screw head during tightening or removing the screw. The head slot employs slot walls that indent in some portion of the wall, the indent portion forming a ledge under which the screwdriver tip may be retentively captured thereby preventing the tip from lifting from the screw slot and stripping the screw head. The screw slot and driver also generally employ a tapered form, such that the slot widens from a central portion out to the outer circumferential edges. The narrow portion of the slot matching in form a narrow portion of the driver tip such that the driver tip tends not to slide off the screw head during use. Utilizing these inventive design concepts prevents the screwdriver tip from slipping off the head and resulting in the need to apply less downward pressure.
