What Size Impact Wrench For Automotive Work – Guide

When working with cars, one of the most important tools is the wrench. A standard socket or bolt tool has sizes that are mostly universal; you can usually get what size fastener you need in any shop.

But when it comes to actually changing out parts, having the right-sized impact wrenches can save you time and energy! An “impact” wrench is one that breaks away rather than using conventional torque settings.

In this article, We will discuss some common automotive work that requires an appropriate-size impact wrench, as well as some tips for buying your own.

What types of automotive work need an impact wrench?

One of the first things you should know about auto mechanic tools is that they come in all kinds of sizes. There are metric-size wrenches, imperial-size wrenches, and everything in between!

Imperial-size wrenches have numbers like 1/8 or 5/16 which mean one-eighth of an inch or five-sixteenths of an inch respectively. These are great because you can easily compare them to other similar-sized objects!

Most people use the word “wrench” when talking about mechanics but there are actually three main types: A Corded Impact Wrench and a Cordless Impact Wrench.

Corded Impact Wrench

A corded impact wrench is a power tool that’s connected to a power source through a cord. The electrical power supply provides continuous power to the tool, making it ideal for heavy-duty tasks that require a lot of torque.

Corded impact wrenches are also typically more powerful than cordless models, making them ideal for larger jobs that require a lot of force.

Cordless Impact Wrench

A cordless impact wrench, on the other hand, runs on rechargeable batteries, allowing you to work in areas where there’s no electrical outlet. 

The lack of cords also provides greater mobility and flexibility, allowing you to work in tight spaces or at different angles with ease. 

Cordless impact wrenches also tend to be lighter and more compact than corded models, making them ideal for smaller jobs or for use in tight spaces.

Air Impact Wrench

An air impact wrench is a tool that is commonly used in the automotive industry to loosen and tighten bolts and nuts. 

It is a pneumatic tool that is powered by compressed air and works by delivering a high torque output with a quick impact, making it easier to loosen stubborn bolts and nuts. 

There are also adjustable wrenches which are not really specific lengths either, instead, they expand or contract as needed.

What size impact wrench should I get?

You will need the right tools when performing any type of automotive work, such as changing or tightening an engine part.

One of those tools is an appropriate-sized socket or bolt puller. A bolt puller comes with a handle and a hook that grabs onto the head of the bolt. Then you use the handle to pull up on the bolt, which can be tricky because sometimes there are nuts attached to it!

You also need an appropriate-sized socket to take off or tighten the correct fastener type. The wrong-sized socket could cause too much friction when trying to turn the fastener, or it could break down due to excessive torque.

There are many different sizes of sockets in the world, but most people agree that 1/2″ (13 mm) diameter sockets are the best overall choice unless you have no other option. These are called half-inch hexagonal sockets and are the standard size used almost everywhere.

It is very difficult to find this outside of specialty tool stores so they are expensive, but they last a long time so it’s worth the investment. Also, you can check Size Air Hose For the Impact Wrench.

How to use an impact wrench?

Many people begin working on cars because they want to have a career in automotive technology or mechanics, but most unfortunately never learn how to properly work with one of the key components of your car!

The word “wrench” comes from the French words roulant, which means rolling, and engine, which means engine or tool. A wrench is a handle attached to a circle (wheel) that fits into other circles (axles). By changing the position of the wheel relative to the axle, you can perform various tasks, such as turning, loosening, or tightening nuts and bolts.

There are many types of wrenches, including Corded Impact, Cordless Impact, socket, and combination. The size of a wrench makes a difference in what it can be used for and how easily it can be used to do so. There are two main sizes of wrenches: metric and imperial.

Metric wrenches have numbers instead of letters to denote their diameter. These include millimeter (mm), centimeters (cm), and decimal mm (1/10th of a meter = 0.01 meter) wrenches. An example would be a 1/4 inch (0.64 cm) hexagonal drive socket wrench. This would be a good choice if you need to change a bolt or nut that has a washer already. A common use for this is replacing the bearing cover on a vehicle door.

How to choose the right impact wrench

To perform any kind of automotive work, you will need the right tools and equipment. For example, if changing out your vehicle’s brake rotors, you will want a proper sized adjustable torque wrenches.

Impact wrenches are one such piece of equipment that many people get wrong. There are two main types of impact wrenches – fixed-speed and variable-speed. Fixed-speed tools only have a few settings typically, while variable-speed ones let you increase the torque setting as the machine allows.

The most common type is the vise grip which uses friction to hold onto the rotating part. This style can be tricky to use properly since you must ensure that enough force is being applied to prevent slippage but not so much strength that you damage the part being worked on.

You will want to make sure that you pick up each one individually to verify that they fit in order to feel comfortable using them.

Tips for impact wrench maintenance

Any tool with moving parts is always at risk of breakdown or damage. Having appropriate tools to fix your vehicle will prevent this!

Most automotive professionals have at least one heavy-duty torque wrench in their collection. These are used to apply pressure to create friction when starting engines or changing gears.

 A common place to use a wrench is during winter service when cars may need more engine start-up energy than normal.

Another important part of an automotive technician’s inventory is a small hex key or Allen screwdriver. This help remove stubborn nuts and bolts from difficult positions. Technicians also keep a pair of leather gloves handy as many components require good-quality lubrication.

General tips:- Always wear protective gear- Never take your eye off of the job for too long- Keep sugary drinks and snacks away to perform routine services

Never drop a bolt onto the ground while it is still hot! This could cause it to crack or shatter which would make reassembling it very hard or impossible. If you must step away, put something cold between your hand and the object to avoid burning yourself.

Cost of impact wrenches

Buying an automotive tool like an impact wrench can seem expensive, but you are sure to use it at least once while owning a car!

Most manufacturers will include free tools when you purchase a new car. These are typically called “accessory” or “aftermarket” equipment because they are not part of the original manufactured equipment package.

However, before buying such accessories, make sure that your car comes with the appropriate size socket needed to fit the bolts on your vehicle. If it does not, then you have wasted money!

There is also no need to spend lots of cash on an expensive tool. There are some great budget alternatives that work just as well if not better than more expensive models.

Impact wrench safety

You should follow some basic rules when using an impact wrench to ensure your safety. Never remove the handle or grip material before putting the head in place! This is what allows you to hit the metal with enough force to cause sparks and ignition.

Make sure your hands are full length away from the body when holding the head. If needed, cover the exposed end of the handle with your other hand to prevent accidental contact.

Never put too much pressure onto the tip as this could result in breaking or bending which would impair function. Only tighten pieces tightly enough so that it feels smooth and light, but not impossible to turn.

We recommend always wearing work-appropriate gloves while working with tools like this to avoid any potential damage to yourself or your house. Make sure to wash your hands immediately after use!

Always keep your eye’s up and look around the area while operating such equipment to make sure you don’t hurt anyone or anything else! These tips will help make your car repairs more safely done.

Time and Torque Testing

One of the most important things to know about wrenches is that there are many different size wrenches, with varying degrees of power.

There are 1/2 inch (13 mm) Corded Impact Wrenches, 3/8 inch (9 mm) Cordless Impact Wrenches, 5/16 inch (8 mm) hexagonal bar end adjustable wrenches, and one very popular set which is 7/32 inch (5 mm) open-ended socket. 

All these different sizes have various terms such as “torque” or “stress” applied to them so that they will not break when used properly.

The term “torque” simply means how much pressure is being exerted on the shaft of the wrench, while the word stress refers to how much force the handle can take before breaking. Both of these apply only when using proper tools!

You will need both imperial and metric sockets when working on an automotive job, as well as a standard and metric driver, and either a standard or metric-sized square drive pinion. You also want to be sure to use a quality tool; anything cheap might break down at the last minute.

FAQ’s

Why should you care about the size of your auto repair tool?

Because some machines require more power than others to start, the size of your torque wrench determines how quickly you can do certain things.

Can you use an impact driver for automotive work?

Yes, an impact driver can be used for automotive work as it provides high torque output making it suitable for tightening or removing bolts and screws in tight spaces.

What size impact wrench do you need to take wheels off cars?

A 3/8 inch or 1/2 inch drive impact wrench is usually sufficient to take wheels off a car. The size of the drive needed is dependent on the size of the bolts or lug nuts on your car’s wheels. 

A 3/8-inch drive impact wrench is more compact and lightweight while a 1/2-inch drive impact wrench delivers more torque.

How many ft-lbs of torque do you need for car tires?

Typically, a torque of around 80-100 ft-lbs is required to secure lug nuts on a car tire. However, it’s best to consult the vehicle’s owner’s manual for specific torque specifications. Over-tightening or under-tightening can cause problems and affect the performance and safety of the vehicle.
