Needle-nose pliers have very narrow jaw tips that let them squeeze into tight spaces, and they are perfect for jobs where precision is needed. You can use them to zero in on the specific point along the wire that needs to be shaped.
The other tools pictured are a chisel, file, and pin punch. A rasp is essentially a very coarse file with a flat surface to smooth surfaces.
A diagonal plier employs jaws whose cutting edges join at a diagonal angle. Unlike scissors, they make a cut by "wedging" the material apart.
A wing nut has "wings" on each side for hand-tightening ease.
Hacksaws are used for cutting metals such as iron, steel, aluminum, and copper.
A car's braking system is controlled by the movement of pressurized liquids.
The tool pictured is a hole cutter bit, also known as a hole saw. They are non-adjustable, so each one can only drill one size of hole.
Wrenches use leverage to apply torque, or twisting force, to a fastener.
A soldering gun is a tool that is often used for soldering electrical connections.
There are two types of wrenches: open-end and box-end. A wrench with closed ends is called a box-end wrench.
A castellated nut uses a cotter pin to lock it into place, which must pass through a hole in the bolt or stud that the nut is threaded on.
The oil pan is where oil drains to; it is the reservoir. When the car is running, the oil pump draws oil out of the pan into the oil galleries.
An outside micrometer is used to measure the diameter of cylindrical objects and can also measure the thickness of a flat object. It is comprised of an anvil, spindle, sleeve, thimble, and ratchet
The ball peen hammer has a regular hammer head on one face and a rounded striking surface on the other face. Common uses are shaping metal, setting rivets, and driving cold chisels.
While cars used to use carburetors to ensure that the air-fuel mixture was correct in its ratio, modern vehicles use an ECM (electronic control modules) to determine the optimum air-fuel mixture.
Generally, making large (bigger than 1/2" diameter) holes is done through a process called boring. This can be done using holesaws, rather than drill bits.
Making a small indentation with a center punch allows a drill to stay on target long enough to get a hole started.
A Torx screw head is star shaped with 6 rounded lobes.
