Applications
of Screwdriver
Screwdrivers
are one of the most necessary and sought-after tools for any tool kit. For
loosening and tightening different kinds of fasteners, there is no option for
screwdrivers. These are used in various applications like
·
Opened the mobile
phones
·
Opened the
Electronics and electrical equipment
·
Opened the
computers
·
Carpentry and
woodworking
·
Mechanical and
industrial production
·
Metal worked and
fastening wood to metal
·
Flammable environments,
etc.
Screwdrivers
Sizes:
The
screwdrivers are available in many different sizes. These are usually sized as
standard large, medium, and small. Certain screwdrivers are also sized to use
in tightening or confined spaces. The screwdriver tip width and the length of
both the blade and the overall tools are generally measured in millimeters.
Again,
depending on the worker, the screwdriver sizing can vary. For example, Phillips
screwdriver provides four standard screwdriver sizes ranging from no 0 to 4,
where #0 describes the smallest screwdriver. On the other hand, certain
screwdrivers are sized based on the Torx size. The size is specified by the
letter T replaced by a number. For instance, T10 screwdrivers. This screwdriver
sizing approach ranges from tiny screwdrivers to T45 and beyond. The same
sizing system is applicable to screws as well which in turn helps in choosing
the screwdriver size for a particular sized screw.
Types
of Screwdrivers;
In
general, screwdriver types are resolute based on the drive tip shape to fit
specific kinds of screws. Again, certain kinds of screwdrivers are specific
tools for particular industries. Using the right kind of screwdriver to the
screw saves effort and, time, the following section gives a guide to the most common
types of screwdrivers.

1: Different Types of Screwdrivers
1.
Crosshead Screwdrivers or Phillips; Screwdrivers;
Crosshead
screwdrivers or Phillips screwdrivers are considered to fit screws with
Phillips heads having a crossed shape recess. These are available in sizes from
size zero to size four. Phillips screwdrivers are imaginary to cope with higher
torsion. Their angled tips allow appropriate deeper into the screw head which
decreases the chances of the driver sliding out.
2.
Torx or Star Screwdriver;
Torx
screwdrivers are most popular by various names like star head screwdrivers,
pointed screwdrivers, or six-point screwdrivers. The trademark name for a
six-point star-shaped intrusion in the screw head is Torx. This kind of
screwdriver is suitable for assigning higher torques without the tool slipping.
Torx screwdrivers are obtainable in a range of sizes. These use a numbering
system that starts with the letter T followed by a number, for example; T8,
T14, T10, T26, etc. With the increase in the numbers, the size of the tooltip
increased. Torx screwdriver is widely used in Automotive, factories, and
industries.
3.
Insulated Screwdrivers;
Insulated
screwdrivers provided added safety in potentially hazardous situations and
because of this, they are also known as safety screwdrivers. These types of
screwdrivers are widely popular among electricians. The insulation is usually
made from non
4.
Torque Screwdrivers;
The
torque screwdrivers are quite similar to a torque wrench and are used to
provide a specified controlled torque. These work using a torque-limiting
clutch that has a limit on the applied force beyond a certain threshold.
5.
Flathead Screwdrivers;
Flathead
Screwdrivers are also known as slot-headed screwdrivers. These types of
screwdrivers are quite common and have multi-purpose applications. With their
flattened tip, flathead screws provide a linear straight movement.
6.
Tri-Wing Screwdrivers;
Mostly
used for specialized implements like consoles, cameras, and mobile phones,
Tri-wing Screwdrivers possess quite small tips to enable use with smaller
screws and bits.
7.
Pozidriv Screwdriver;
A
better version of Philips Screwdrivers, Pozidriv screwdrivers are designed to
reduce cam-out whenever a screwdriver slips out of the screw head on the
application of more torque.
8.
Hex Screwdriver;
As
the name hints, they, are hexagon screwdrivers used to work with hex screws.
Allen keys or wrenches are representative examples of Hex Screwdrivers.
9.
Square Screwdriver;
To
reduce the cam-out issue of the slotted screws and speed up the fastening
procedures, the square-headed screwdriver that fits screws with a square-shaped
recess was developed.
10.
Electric Screwdrivers and Impact Drivers;
Electric
Screwdrivers are compact powered tools required for various tasks like
assembling furniture or screwing into softwood or other similar material.
Whenever, Impact drivers, are essentially more heavy-duty screwdriver kind that
is used for jobs requiring sudden force to drive into or removed from harder,
denser materials.
11.
Precision Screwdrivers;
Precision
screwdrivers are suitably used for very few devices whenever extremely small screws
are used. Representative examples are mobile phones, watches, etc.
12.
Magnetic Screwdrivers;
Magnetic
Screwdrivers have an inherent magnetic force that allows the screws to be
attached at the tip. These are found in major applications in the electronics
industry where screws are small and have a high potential to be dropped simply.
13.
Ratchet Screwdrivers;
With
a built-in mechanism, these allow the application of force only in one
direction while allowing free movement in the alternative direction, Ratcheting
Screwdrivers work similarly to ratchet spanners.
