Most Common Craftsman Drive Sizes

The small square connection fitting of the socket wrench that sits on the ratchet is called the drive. Various sizes take a different number of sockets, which can be metric or SAE. (Read Sae to Metric conversion Chart)

Although there are various sizes available, the three conventional sizes are the most common.

  • 1/4″ Drives: These are often used for low-torque tasks and are only suitable for sockets up to 14mm in diameter.
  • 3/8″ Drives: These are the most versatile, since they can cover sockets for jobs around the house, as well as your car and many other places.
  • 1/2” Drives: Typically used for larger jobs on automobiles where the nuts are larger and require greater torque. They’re used for sockets with a diameter of 19mm and higher.

Types of Sockets

While you may have a considerable number of metric and SAE standard socket sizes, the wrenches you use to use them may vary.

It’s easy to see why the following wrenches have swiftly become some of the most popular tools in the shed.

Impact Sockets

Numerous people use hand tools, yet many sockets are incompatible with them. Impact sockets are made to work in conjunction with these other tools. An electric wrench or pneumatic impact wrench is a good example.

You’ll require socket sets designed to resist these greater torques if you use these. These sockets will be more durable than standard sockets and suitable for smallest to largest socket sizes with adapters.

Socket Point Number

A 12-point socket is practical and simple to use. It can be slipped over the hardware in any of 12 locations, making alignment easy.

On the other hand, six-point sockets have been chosen for more significant hardware situations that require substantial torque. While 12-point sockets are well suited for most light and household tasks, six-point sockets have been chosen for more significant hardware situations that require substantial torque.

In this case, six-pointers have a decreased risk of slipping. Because its inner walls are positioned against all six sides of the hardware, a six-point socket is more durable than a 12-point.

Shallow vs. Deep Sockets

If you’re working in a restricted location, conventional shallow sockets may not be able to touch a nut or bolt before the top of the stud or bolt touches the top of the socket. A notable example is spark plug sockets, as well as various wheel nuts.

What Size Sockets Does Craftsman Make?

While the company makes the complete socket set sizes above for the smallest to the largest SAE sockets, you can find the socket sizes for metric.

You’ll notice here that as metric is deemed more accurate, there are no half-size metric sockets as they increase in increments of 1mm.

Here you can see the metric socket size chart from Craftsman. Several of these are the same size as SAE, yet you will see such sockets where the metric size converts in the later SAE to metric conversion chart. (Find the Best Deal on Socket Sets)

How Do I Know My Socket Size?

How are full socket set sizes measured is often asked, and it is here it is good to learn how to read socket sizes. It is of little use to have a 1/4 inch drive, and you are searching 3/8 socket set sizes to get one to fit. You’ll find the 3/8 drive socket set sizes more common socket sizes than 1/4 socket set sizes.

When you want to know how to establish socket size, it helps you understand knowing how are sockets measured.

There are two systems for calculating socket head sizes: metric (millimeters) and imperial (inches).

The size is always stated in imperial measures, regardless of whether the drive socket is imperial or metric. Sockets come in a variety of sizes and are offered in sets.

Sizes in Imperial

The term imperial has been used to refer to the US weights and measures system since 1965. At the same time, the United Kingdom began to use the metric system.

Imperial socket head sizes range from 5/32′′ to 1 1/2′′ or more and are measured in inches and fractions of an inch.

Imperial vs. metric sockets is mostly utilized in the United States, although with more Asian manufacturers producing parts, the metric is becoming more popular.


The Society of Automotive Engineers is an American standards organization. SAE is a not-for-profit association that focuses on transportation-related industries like automotive and aerospace. (Find the Best Ratcheting Wrenches For The Money)

SAE is intimately linked to imperial size sockets because sockets designed for use in the American automobile sector must adhere to SAE regulations.

Metric socket size chart

Metric System

The metric measurements of a socket set are in millimeters. The standard metric socket head size is usually between 3mm and 80mm.

Because the metric system is now the most widely used measuring system on the planet, you can find typical metric bolt sizes and metric socket sizes in every country.

Because more products are arriving in the United States from foreign countries, there is no need to worry about whether you need an imperial or metric socket.

What exactly is AF?

The American fractional scale is used to measure sockets and socket sets. When European manufacturers use metric sockets and Americans use imperial sockets, the term AF might be confusing because it has two meanings.

American Fractional is abbreviated as AF, which is also a synonym for imperial. When used with metric sockets, however, AF stands for “Across Flats.” An 8mm AF socket, for example, will fit a bolt head with flats that are 8mm broad.

To add to the confusion, some socket manufacturers use the abbreviation AF to refer to their high-quality anti-slip sockets, which apply force to the flats of your bolt head rather than the corners.

What is the Drive Size of a Socket?

14-inch, 3/8-inch, and 12-inch drive sizes are offered for a metric socket set, Imperial sizes, and other unique variations you could come across.

With the main to, each needs a unique ratchet and additional attachments like an extension. Different socket sizes use larger drive sizes, while smaller sockets use smaller drive sizes. Besides this, you find common ratchet sizes and an adapter that enables you to use one ratchet on smaller socket tools to meet your needs.

Common socket sizes are available in a variety of socket sets that are metric and imperial. You can even find they come as a combination socket set and accommodate a wide range of socket types from the one ratchet handle.

The drive socket’s dimensions have four common socket sizes and will always be measured in imperial units as it is an international standard. The drive socket size most common are 1/4″, 3/8″, 1/2″, 3/4″, or 1″.

Small hand tools socket sets will be 1/4″ or 3/8″ drive sockets as they are better suited to work in tight spaces.

Large socket sets can be 3/4″ or 1″ drive sockets as these tools are needed for larger fasteners. A greater socket size means a larger drive socket, and which can deliver high force and torque without putting the tool in harm’s way. (Find the Best 3/4 Drive Jumbo Socket Set)

What is The Order of Sockets?

When you want to know how to organize sockets by size, you can use this chart as a comparison. Metric units run up in numbers, yet you may need a guide to order your SAE sockets from smallest to the biggest socket, and keep your socket sizes in order.

Most often, you’ll use a certain number of sockets to deal with an exhaust system, or for larger sockets where you are driving large lag bolts, wall studs for your flat screen tv, and often your car’s lug nuts when changing tires.

In these instances, you’ll be glad of the socket organizer that comes with your sockets and the socket size chart.

Here you can find the SAE to metric conversion chart running smallest to largest and where metric sizes match the SAE equivalent. The biggest ratchet size would most often be 1-inch, yet even this is held back for more substantial jobs.

    Not a complaint, but an observation: I still have a few Whitworth (“Wentworth”) 1/2″ drive sockets in my toolbox. Leftovers from my MG TD days. They differ from both SAE and metric sizing.
