Failure to which, you will end up using a lot of time, get fatigued and destroy tools or parts. You can even end up bruising yourself. It is therefore very important for you to use a correct tool for every piece of work. Below is a comprehensive and in depth guide for 25 automotive repair tools for every successful workshop
Spanners are also called wrenches. They are of several types and used for different specialties when needed. Wrenches mostly used in an automotive workshop are, ring spanners, open-ended spanners, combination spanners, flare-nut spanners, adjustable spanners, spark plug spanners , impact wrenches, air wrenches and pipe wrenches.
A. Ring spanner.
It is also called a box-end spanner. The ring spanners are of different sizes. The two diameters are not the same. They loosen or tighten bolts where sockets do not fit.
B. Open-ended spanners.
The open ended spanners are open in both sided hence the name and are also of different sizes. They are recommended for general use. They loosen or tighten bolts mostly when loosen since ring spanners tend to be tedious.
D. Combination spanners.
A combination spanner has one side closed and the other open. They are usually of same size and take the advantage of both the ring spanner and the open ended spanner.
C. Flare-nut spanners.
They are also called open-nut/fitting/line spanner. They are usually a variation of the open end spanner. Flare nut spanners are used on fittings associated with pipes and tubings and provide better grip.
E. Pipe wrench.
Used to tighten or loosen pipe fittings. Have jaws that exert a lot of force to grip them.
F. Adjustable spanners.
An adjustable spanner has a knob that is used to adjust its head size to fit the head of a nut or a bolt.
G. Impact wrench.
An impact wrench is a wrench that makes use of electricity to produce mechanical rotary toque to loosen or tighten a bolt or nut. Those that use brushless motors are the best.
H. Air wrench.
An air wrench is a wrench that makes use of compressed air to produce mechanical rotary toque to loosen or tighten extremely hard bolts or nuts.
When there is not a lot of pressure involved, ratchets make it easier to tighten or loosen bolts and nuts. They can turn in either direction as set by the user.
3. TORQUE WRENCH.
A torque wrench or tightening wrench is used to tighten nuts and bolts to manufacture’s specifications. When ordered to use torque specs, make sure you are accurate; too much torque on the bolt or nut might lead to breakage of what is being fastened. This sometimes can be what we call an expensive mistake.
Sockets are of different sizes to fit the different sizes of bolts nuts. However, when using an impact wrench the right type of socket must be used, usually those with six sides. This is important because using the sockets with 12 sides are not strong enough and can either get destroyed. They also don’t grip as to per the toque ability of the impact/air wrenches and could lead to rounding of nuts and bolts
5. SQUARE DRIVES.
Square drives are of different sizes. They a used with sockets of different sizes too, the harder the work that needs to be done the bigger the square drive a still the socket.
6. BREAKER BARS
Also called adjustable offset handles. They are long and give leverage when doing heavy loosening or tightening. A large space is needed for them to operate well.
Are used to hold parts together e.g. when welding. Also used when dis-assembling leaf springs because of their tension. G-clamps of the right size must be used.
8. SLIDING TEE-HANDLE.
Its handle is sliding and hence can be held by two hands. Provides better leverage too as its positions are adjustable which clears obstructions when loosening or tightening bolts.
9. SCREW DRIVERS.
There are different types of screwdrivers used in the workshop for various purposes. Two main screw drivers are the flat-head screw driver and the Philips star.
A. The flat head screw driver.
It is the most common type of screw driver in a workshop. As its name suggests, it is called a flat head because its blade is usually flat.
Safety rules must apply when working with the flat head screw driver.
B. The Philips star screw driver.
10. MICROMETER SCREW GAUGE.
A micrometer screw gauge is a precision instrument used to measure accuracy and distance. They are of different types each measuring its own place. They measure either outside distances, inside distances and depth with each measurement and its own tool.
A. Inside micrometer.
Used to measure inside distances.
B. Outside micrometer.
It is a general type, and used to measure outside precisions.
11. TELESCOPIC BORE GAUGE.
Used together with a micrometer to measure distances at awkward spots.
12. VANIER CALLIPERS.
It is also a precision instrument that is used to measure dimensions requiring high level of accuracy.
Has a both internal and external jaw that catches the work to be measured. It can also measure depth at its end through a caliper slide.
13. STRAIGHT EDGE.
It is a long straight rule that is flat and used together with feeler gauges to measure flatness of a surface.
14. FEELER GAUGES.
Used together with a straight edge to measure clearances and narrow gaps
It is a hardened and tapered tool made of tool steel. A scribber is used to make sharp clean lines on metals.
16. STEEL RULE.
They are rulers made of steel. They measure precisions of up to a millimeter.
17. GASKET SCRAPPERS.
Gasket scrappers are used to scrap remains of old gasket so that a new one can be put. Make sure you understand the safety measures and the reason as to why you should use a gasket scrapper.
Different types of punches are used in a workshop. Those mostly used are, pin punches, prick punches and center punches.
A. Pin punch.
They are used to drive out rivets or pins and are available in various diameters.
B. Center punches.
Center punches are used to mark indentations to direct where drilling begins.
As the name suggest, anti-seize is a compound when used, two metals joined together cannot form a permanent join although fastened together. Used in nuts and bolts to prevent rust and helps make work easier when
Just a single vice in a workshop is not very efficient. However, several vices are used in professional workshops for various specific jobs.
A. Drill vice.
For a work to be drilled, it must be positioned and locked in a specific place.
B. Bench vice.
It is the most common type of vice in a workshop, have serrated jaws to give it an extra grip. If a danger exists that whatever is being griped can be marked or get destroyed, soft jaws are used.
C. Offset vice.
Used to grip awkward objects that cannot be gripped vertically with an bench vice
There is simply no workshop without pliers. This is because pliers are used almost everywhere in auto repair. Some of pliers used in a workshop are, combination pliers, needle nose pliers, long needle nose pliers, pinter pliers and circlip pliers.
A. Combination pliers.
Are used as general purpose work tools in the workshop. Have different functionalities for gripping and cutting.
B. Circlip pliers.
C. Long nose pliers.
Are special pliers used to reach spots where others cannot.
D. Pinter pliers.
They are used to cut angles. Leverage is added by rolling them on the curve of the jaws.
There are different types of chiesels used in an automotive workshop. Mostly used includes flat chiesels and close cut chiesels.
A. Cross cut chisel.
Their edges are cross-cut and sharpened. Cross cut chiesels are used for cleaning and making key ways in grooves.
B. Flat chisel.
23. ALLEN KEYS.
They are hexagonal in shape and are designed to fit in sockets. Allen keys come in sets of respective correct sizes.
Hammers are very important in every workshop. That is why different types of hammers have been made to suit different types of work in an automotive workshop.
A. Ballpeen hammer.
This is the most common hammer in an automotive workshop. It is also called an engineer’s hammer. It has a hardened steel head.
B. Lamp hammers.
They are the largest and strongest hammers in the workshop and are used for strong blows. Lamp hammers are made of high carbon steel.
C. Dead blow hammer.
It is designed in such a way that when it hits something, it will not bounce back. Care must be taken when using a dead blow hammer.
