The SAE Socket Size Chart provides a handy reference for the different socket sizes in inches and their equivalent fastener diameters. This chart is useful for anyone working with SAE sockets and fasteners, as it allows for easy identification of the appropriate socket size for a given fastener diameter. By using this chart, users can ensure that they select the correct size socket for their specific application, thus avoiding potential issues such as stripped fasteners or incomplete tightening.


What is a SAE socket size chart?

A SAE socket size chart is a reference guide that provides information about the corresponding sizes of SAE sockets for different fastener measurements.

What are the common SAE socket sizes?

Common SAE socket sizes include 1/4 inch, 3/8 inch, 1/2 inch, 5/8 inch, and 3/4 inch, among others. These sizes are used to match the specifications of different nuts, bolts, and fasteners.

How do I read a SAE socket size chart?

To read a SAE socket size chart, locate the measurement of the fastener (such as the bolt diameter) and then find the corresponding socket size listed on the chart. This will ensure that you use the correct socket for your application.

Can I use an SAE socket on metric fasteners?

While SAE socket sizes are primarily designed for imperial or inch-based fasteners, it is possible to sometimes use an SAE socket on metric fasteners if the sizes are relatively close. However, it is generally recommended to use metric sockets for metric fasteners to ensure a proper fit.

Are SAE socket size charts universally standardized?

No, SAE socket size charts may vary slightly based on manufacturer or region. While there are standard sizes that are commonly used, it is important to cross-reference the specific chart you are using with the tools you have to ensure compatibility.
