TIGHTENING, REPAIRING, AND ADJUSTING TOOLS
USING CORRECT PROCEDURES:
Proper maintenance of equipment requires experience,
training and using the right tools. Mechanical
maintenance requires hand tools, torque tools, special
flaring tools and other specialized tools. In making
repairs in the computer laboratory means that you have
to use the right equipment and supplies so that every
repairs that you will do is right.

TIGHTENING, REPAIRING, AND ADJUSTING TOOLS
USING CORRECT PROCEDURES:
The smartest rule for purchasing tools is to buy good quality products.
High quality tools are not only safer to use, but most of them last a
lifetime with proper treatment. Typically, you can define a quality tool if
when using it the metal pieces are smooth and polished, and the tool is
well balanced—it fits easily into your palm. Inferior machines, on the
other hand, have faulty or rough metals (often concealed by paint) and
show primitive machining. However, the most important thing is that
good resources are better to use. Cheap tools can break up and cause
accidents.

13. There Are A Number Of
Different Types Of Drills
And Fasteners On The
Market. Sifting Through All
Options Can Be
Overwhelming, So In This
Section We'll Give You The
Specifics You Need To
Choose The Right Drill Or
Fastener Tool.

DRILLS
Three sizes of drill bit holder are
available for power drills: 1⁄4-
inch, 3⁄8-inch and 1⁄2-inch
capacity. The two most common
sizes are 1⁄4 and 3⁄8 inches. The
1⁄4-inch drill has a capacity of
1⁄4-inch drills in metal and 1⁄2-
inch drills in wood. A 1⁄4-inch
drill can perform only a small
range of drilling operations and
should not be used for
complicated tasks, but it is the
least costly type of electrical drill.
15
16. 16

The two primary styles of hand
drills are the push drill and the
hand brace. Push drills are
useful for making the pilot holes
and setting the hinges. A hand
brace is especially useful when
operating in restricted areas due
to its ratchet function.
PUSH DRILLS
HAND BRACE

HAMMERS
The most common hammer is a
carpenter's curved nail hammer; 16
ounces is a reasonable size for men and
14 ounces for women. It is steel-coated,
wood-coated or steel-coated and used to
drive nails and other fasteners. The claw
at one end of the head is a two-legged
arch used to dig nails out of wood. The
other parts of the head are the face and
the eye. A flat-faced or flat-faced
hammer is ideal for beginners to use, but
it is more difficult to push a nail flush to
the work surface.

RUBBER MALLET
A rubber mallet comes in handy
when you're trying to break
down painted windows or have
to do light hammering on
surfaces that can be harmed.
Other specialty hammers
include a ball-peen hammer for
metal working and a mason
hammer for brick and mortar
projects.

SCREWDRIVERS
Each toolbox should have one
set of high-quality
screwdrivers that are only
used for tightening and
loosening screws. There are
several types of screwdrivers,
which differ depending on
the screw head, each of
which is made to match.
19
20. HERE ARE THE MOST COMMON SCREW HEADS:
20
Standard head - Also
referred to as a flat,
slotted, or straight
screwdriver. Make sure
that the tip is the correct
width and thickness to
match the screw-head slot.
Phillips head - Often
known as cross or X-
head screwdrivers,
the Phillips head fits
into a cross-shaped
recess in the screw
or bolt head.
Torx head - Torx head (or
similar designs called
Robertson) screwdrivers
fit into a square or
hexagonal socket, which
allows more torque to be
used to tighten or loosen
the fastener.
21. 21
WRENCHES
The purpose of the wrench is to
turn the head or nut of the bolt.
Choosing the right wrench
depends on the nature and size
of the fastener. It can also
depend on how difficult the
fastener is to hit. Wrench styles
include the open end, the mix,
the flexible one and Allen.
21
22. 22
TYPES OF WRENCHES
1.Box end - The box or closed end wrench is used
where there is space to position the wrench around the
fastener. Box end keys are available in 6-and 12-point
models to match the number of sides on the fastener.
Hexagon fasteners have six sides, or points, and are the
most common.
2.Open end - This form of wrench is used for turning
fasteners in places where the end-of-box wrench

TYPES OF WRENCHES
3.Combination - A combination wrench has ends that
carry out unique tasks. One end may be open and the
other closed, one may be offset and the other straight,
or the two ends may be fractionally different in
dimension.
4. Adjustable - The adjustable wrench can be used in a
number of fastener sizes. The downside is that it is less
stable than a fixed-size wrench and can easily hurt you
or damage the fastener. Adjustable wrench can only be
used if the correct size wrench is not available.
23
24. 24
TYPES OF WRENCHES
5. Socket - The socket wrenches fit over the fastener,
making removal simpler and safer than most wrenches.
Sockets come in regular and extended depth;
extensions are available to make it easier to remove
fasteners. They are mostly bought in sets by the size of
the drive.
6. Allen – called by the brand name Allen, they are used
on fasteners with a hexagonal hole in the head. Allen
wrenches are available with an L-or T-shaped handle.

FASTENERS
25
A fastener (US English) or fastening (UK English)[1] is a hardware device that
mechanically joins or affixes two or more objects together. In general, fasteners
are used to create non-permanent joints; that is, joints that can be removed or
dismantled without damaging the joining components.[2] Welding is an example of
creating permanent joints. Steel fasteners are usually made of stainless
steel, carbon steel, or alloy steel.
26. 26
PLIERS
Think of pliers as the extension of
your fingers, just bigger. They're used
to grab and hold a part of it. Pliers
should not be used as fasteners to
tighten or loosen fasteners. Popular
types of pliers include slip-joint,
groove-joint, needle-nose and locking.
26
27. 27
PLIERS
1. Slip-joint – This type of pliers has two settings in
the handle that allow for two widths. Once the
correct width is chosen, the handles are closed
together to force the jaw around the part and hold
it securely.
2. Groove-joint - Groove-joint pliers are similar to
slip-joint except that they use an elongated hole in
the handle with grooves that allow for several
widths.

PLIERS
3.Needle-nose - This type has jaws that
come to the point of firmly grasping
small parts or wires, particularly in tight
locations.
4. Locking - Sometimes called Vise Grip
brand name, the locking pliers are
adjustable and can be locked to hold the
part in place.

5. PLIERS WITH A BITE- If removing
stripped screws is part of your job
description, then grab a grip and buy
a pair of VAMPLIERS. The jaws have
vertical and horizontal clamps built to
carry small, round screw heads. This
thing really does latch on the screws
better than the regular pliers, and all
the editors here at CPT were pleased
by the high-quality feel of the tool.

PHILIPS HEAD SCREW
DRIVER are the ones
that are used to tighten
or loosen screws that
are cross-headed.
Torx screwdrivers are
used to fasten or loosen
screws that have a star-
shaped depression; these
screwdriver tips have a
firmer grip and do not
move easily when
fastening
FLAT TIP SCREW
DRIVERS-are flat-
headed and used
to turn slotted
screws.

Wire cutters are
helpful in
stripping and
cutting wires as
per one’s need
Needle-nose pliers provide
the consumer with cutting
and holding functions.
They are particularly
useful in hardware and
electronics repair; because
of their pointed needle-like
tip, they come in handy
when the nut or element is
stuck in the otherwise
unreachable cranny of the
motherboard.
A nut driver, similar in
appearance to a
screwdriver, is an integral
part of a computer repair
toolkit. They are used to
fasten bolts and nuts of
different sizes. They have a
hollow shaft that gives them
the strength of the threaded
nut.

The crimpers are used to link
wires in such a way that they
are capable of transmitting data.
By deforming either one or both
of the wires, two wires are
connected together with the aid
of a crimping tool. - of the wires
to be attached is first put in the
connector jack and then
compressed and held together to
form a uniformly conductive
wire.
Wire strippers are pliers that help
strip the wire off its insulation. In
general, the wire is covered with
an insulating material cover. If
the situation requires, the wire
must be stripped of all its
insulation cover to be used, e.g.
as a connector or cable. A wire
stripper consists of a pair of
blades that act like a pair of
scissors.
