Mechanics who work on automobiles often need special tools to get the job done. A spanner wrench is a type of speciality wrench designed to help mechanics tighten and loosen nuts on car wheels, as well as other components in different locations. These wrenches are often referred to as “crow’s foot wrenches” for the distinctive shape of their head. The specific type of spanner wrench you need for your project depends on where the nuts and bolts are located. Cars have many different nuts and bolts that must be tightened or loosened depending on the needs of the moment. Whether it’s fasteners under the bonnet or those that hold together body panels, there are several locations where a mechanic might find them with a special tool called a spanner wrench, also known as either a stubby wrench or a crow’s foot wrench, depending upon what type of nut or bolt they are working with.
A spanner wrench is a type of wrench that is designed to fit nuts or bolts that are located in places where no ordinary wrench can reach, such as on the underside of a car’s engine. These wrenches are designed with a long handle to keep the mechanic’s hand away from the area where the bolt or nut is being worked on. There are several types of spanner wrenches, including stubby wrenches and crow’s foot wrenches. Stubby wrenches are short wrenches with a long handle, typically up to 36 inches long. These are typically used when there isn’t enough clearance between the mechanic and the part to be worked on. Crow’s foot wrenches have a longer handle and are used for reaching further places.
Stubby Wrenches - Normally, when you are working on a car’s nuts and bolts, you have access to both sides of the nut or bolt. The only time you need to use a special wrench is when you are trying to reach an odd angle or you don’t have the clearance to get to the nut or bolt. In these situations, you might need to use a stubby wrench. This wrench is designed to fit nuts or bolts even if they are close to your hand. Crow’s Foot Wrenches - If you need to reach deeper than your hand can go, or if your car has a specially designed bolt whose head cannot be accessed from the top, you will need a crow’s foot wrench. Crow’s foot wrenches are designed with a long handle and a “V” shape at the head. This wide head allows the wrench to fit over nuts or bolts that are further away than a normal wrench can reach.
If you know what type of spanner wrench you need and where it is, use these instructions to put it to work. - Step 1 - Choose the Right Spanner Wrench - Look at the nut or bolt and find out which type of spanner wrench will fit it. If you can’t find the spanner wrench that would fit your nut or bolt, you might have the wrong wrench for the job. - Step 2 - Get into Position - Open the hood, lift the car’s chassis, or do whatever is necessary to get yourself into the right position to work on the nut or bolt you need to tighten or loosen. - Step 3 - Apply the Right Amount of Pressure - Tighten the nut or bolt as much as you can by hand. If you can’t get the nut or bolt tight enough to stay in place, use the spanner wrench to finish the job. - Step 4 - Take the Spanner off - Once you have the nut or bolt tightened or loosened enough, take the spanner wrench off and close the hood. If you aren’t done working on that area of the car, put the spanner wrench where you can find it again easily.
There are some situations where you will always need a spanner wrench. Other situations where you might need a spanner wrench to depend on the car you’re working on, its age, its design, and the part you’re trying to work on. For example, you might need a spanner wrench any time you are trying to work on the nuts and bolts under the hood of an old car. If you have an older car where the hood is held up with a cable and several different lengths of bolts, you might need to use a spanner wrench to tighten or loosen all of them. You might also need a spanner wrench if you are trying to work on the nuts and bolts that hold together a car’s chassis.
A spanner wrench is a type of wrench designed to fit bolts or nuts in places where no ordinary wrench can reach. There are several types of spanner wrenches, including stubby wrenches and crow’s foot wrenches. If you need to reach beyond your hand’s reach, or if you need to fit over a nut or bolt that curves down, you will need a spanner wrench.
