Usually, it also involves a mating toolsuch as a screwdriverthat is used to turn it. The following heads are categorized based on frequency, with some of the less-common drives being classified as "tamper-resistant".
Most heads come in a range of sizes, typically distinguished by a number, such as "Phillips 00". These sizes do not necessarily describe a particular dimension of the drive shape, but rather are arbitrary designations.
Slot screw drives have a single horizontal indentation the slot in the fastener head and is driven by a "common blade" or flat-bladed screwdriver.
This form was the first type of screw drive to be developed, and for centuries, it was the simplest and cheapest to make. Additionally, it is unique compared to other common drives, due to it being straightforward to manufacture the slot head, and the ability to be driven by a simple handtool.
The slotted screw is commonly found in existing products and installations, along with use in simple carpentry work and in applications where minimal torque is needed.
Slot screws are also used in the restoration of antique furniture, vehicles, and equipment. However, this design is not well—suited for installation by power toolsgiven that a power driver often slips out of the slot; this often causes damage to the screw and surrounding material. For this reason, cruciform-slotted along with drives have replaced the slot drive in numerous applications. A hollow-ground screwdriver is less likely to cam out leave the slot due to the torque being translated into an axial force — similar to that encountered with Phillips drive but dependent only on driver bladeso more torque can be applied without damaging the screw head.
Note that it is this typical chisel shape which allows 9 screwdriver sizes to drive 24 different slotted screw sizes, with the drawbacks of not fitting as closely as a hollow-ground screwdriver would, and increasing the possibility of damaging the fastener or surrounding area.
At least one mechanical method of temporarily holding a slotted screw to a matching screwdriver is available, the Quick-Wedge screw-holding screwdriver, first manufactured by the Kedman Company in the s. Dzus fastenerswhich have a cam-lock body instead of a threaded body, use a slot drive. Coin-slot drives are so-called because of the curved bottom of the recess, which facilitates driving them with a suitable coin. They are often used on items where the user is not likely to have a screwdriver when needed, such as recessed screws that attach cameras to tripod adaptersand battery compartments in some equipment such as children's toys.
Hi-Torque slot drives were designed by Alcoa Fastening Systems, for situations where very high torque is needed, along with the ability to repeatedly install and remove the fastener.
A cross or double-slot screw drive has two slots, oriented perpendicular to each other, in the fastener head; a slotted screwdriver is still used to drive just one of the slots. The advantage is that they provide some measure of redundancy: should one slot be deformed in service, the second may still be used and the tool cannot slip out.
The following are screw drives based on a cruciform shape; i.Their rounded top will extend slightly above the mating surface when seated in a countersunk recess and may be considered a design element. The external machine screw threads mate with tapped holes and nuts; the "A" suffix denotes they are fully threaded. Select from Class 4. Steel, plain finish, and stainless steel thread tolerance is 6g and plated steel is 6h; right-hand threads are standard. Oval head screw length is measured from the largest diameter point of the head—where the rounded top meets the conical bearing surface—to the tip.

The design off the screw head was to accept a driver that had a 57 degree point with tapered wings that came to a sharper point, this enabled the driver to be released from the screw when excessive torque was applied. The Pozi-drive was invented to further improve on the torque and cam-out of the Phillips head.
To do this there was a second cross added to the first cross. This not only helped when distinguishing between the two head types, it also further improved the contact of the driver to the screw.
A different screwdriver is needed for use with each screw. The new screwdriver for use with a pozi-drive screw has a blunt point rather than a sharp point and the angle of the blades are sharper by 45 degrees. One of the most common problems with the screws are that to the untrained eye both recesses look the same. A Phillips Driver will fit into a Pozi screw head but a Pozi driver will not fit into the Phillips screw head, it is not recommended to use a Phillips driver with a Pozi screw as it will eventually round off the recess of the head causing damage to the screw and making it unusable.
