best socket set

Every car mechanic should own a complete socket set for car maintenance and other automotive tasks. The best sets include hundreds of sockets and wrenches that are organized inside of a rugged tool box.

The best socket set is the DEWALT DWMT75049, which is a 192 piece set that is designed for mechanics performing car maintenance.

Unfortunately, there is no single socket that is suitable for all nuts and bolts. This means you will need to own various socket sizes to complete all tasks. To avoid disappointment, we advise that you buy from reputable brands that are known for their high standards and have spare sockets available in case you lose any.

Socket Set Buying Guide

If you are a mechanic or enjoy working on your own cars, then a socket set is essential. Without a range of sockets, you won’t be able to remove all the different types of nuts and bolts on your car. You have the choice of getting a whole range of different sockets with some sets containing over 500 sockets in total.

To help you make an informed buying decision, we have produced the below guide regarding socket sets.

Socket Size Comparison

A big mistake that many beginners will do is only purchase a few socket sizes to save a bit of money. However, you can guarantee that when you are half way through working on the car, you will need a socket size that you do not have.

Mechanics from the US will use a different dimension system (dual inch) over foreign cars that use metric sizing. Knowing the exact measurements of each will give you an insider to the correct socket set to buy. Below is a socket set comparison chart for each dimension.

Bolt DiameterSock Size (Dual Inch)Socket Size (Metric)
1/8 inch5/8 inch8 mm
3/16 inch3/8 inch10 mm
1/4 inch7/16 inch11 mm
5/16 inch1/2 inch13 mm
3/8 inch9/16 inch14 mm
7/16 inch5/8 inch16 mm
1/2 inch3/4 inch19mm
9/16 inch13/16 inch21 mm
5/8 inch15/16 inch24 mm
3/4 inch1-1/8 inches29 mm
7/8 inch1-5/16 inches34 mm
1 inch1-1/2 inches38 mm

Its important to note that sockets can come in different lengths that include shallow, semi-deep and deep. To the average household user or mechanic, you will only need shallow and semi deep sockets.

However, if you are working on cars frequently, investing in the best socket set with deep sockets will give you the edge when working on hard to reach bolts or nuts.

Socket Set For Mechanic

Socket Drive Size vs Socket Size

Many people confuse the drive size to the size of the socket itself. The socket drive size is the rear of the socket that attaches to the wrench and there are only a few, that include:

  • 1/4 inch
  • 1/2 inch
  • 3/4 inch
  • 1 inch
  • 1-1/2 inch
  • 2-1/2 inch

Socket sizes come in a whole range of sizes as shown in the table above but they are just the most popular sizes. It is worth mentioning that if you plan on using a cordless impact wrench that use the same drive size, you may want to check the max torque that they can handle. This is because an impact wrench may increase the chances of cracking the socket.

6 vs 12 Points

The part of the socket that is put onto the nut or bolt head is known as the point. The shape is either a 6 pointed hexagon or a 12 pointed star shape where both have their own benefits and drawbacks. To begin with, the 6 pointed socket is the stronger of the two because the inner walls sit flush on the hardware and include thicker walls.

12 point sockets provide convenience as they can be placed on the nut or bolt in any of the 12 positions. For hard to reach nuts and bolts, this can be really useful but it is important that you only use them for light work applications.

Socket Set For Car Maintenance

Deep vs Shallow Sockets

Not every nut and bolt are the same and you make need either a shallow or deep socket to accomplish a certain job. For example, you may have a nut that sits more than an inch below the top of the bolt that it is attached too. If you were to use a standard socket, it may struggle to touch the bolt as it may hit the end of the socket.

Therefore, having some deep sockets to hand will ensure you are able to reach awkward sockets such as seated spark plugs and much more.


Whether you need a complete set of sockets or an extra set for smaller jobs, all of our recommendations cover both requirements. Investing into a quality socket set for car maintenance that comes with a warranty is highly recommended. There is nothing worse than cracking a socket and not being able to get it replaced.
