The various drives:

Slot screw drive:

The drive has a single slot in the screw head and is driven by a flat-bladed
screwdriver. This was the first type of screw drive developed. The screwdriver
is sometimes called a flat-blade, flat-tip, slot-head or a flat-head
screwdriver.

Phillips:

The drive was invented by Henry F. Phillips. The Phillips screws have cross-slots that look
like an X stamped into the head. The drive was patented in the 1930’s. This
drive was invented to become a vast improvement from the antique slotted screw,
which tended to cam-out easily. Nowadays, the Phillips screw is easily mistaken for
a Pozidrive screw.

Pozidrive:

The drive is an improved version of the Phillips drive. Greater torque can be
applied on a Pozidrive screw. The Pozidrive screws and the screwdriver can be
distinguished by a second set of radial indentations set at a 45° from the
cross recess. The design is intended to decrease the likelihood that the
Pozidrive screwdriver will slip out. The disadvantage of the Pozidrive is that
is visually similar to Phillips and that many people are unaware of the
difference or do not own the correct screwdrivers.

IMPORTANT:
The screws having a pozidrive head can be unscrewed by a Phillips screwdriver,
but a Phillips screw cannot be unscrewed by a Pozidrive – It will severly
damage the screw and the tip of the screwdriver.

Robertson (Square drive):

The drive is also known as a square drive. Some people might refer to it as
Scrulox screw drive. The screw head has a square head. The tip of the
screwdriver is tapered to make it easier to insert into the screw. Robertson
screwdrivers are easy to use with one hand. It also allows the screw to be
placed on the screwdriver prior to driving it in position.

Torx:

The drive uses a star-shaped recess in the screw head with six rounded
points. It is designed to permit increased torque transfer compared to other
screwdrivers. Torx is very popularly used in the automotive, electronics and
woodworking industries. It has a very high resistance to cam-out and has an
extended bit life.

Security Torx:

The drive is similar to the standard Torx drive, but has a small pin in the
centre of the recess. This drive is also referred to as a tamper-resistant
Torx drive.
