Socket Size Chart: Metric and Standard (SAE)
A socket size chart is essential for anyone working with fasteners․ It provides a quick reference for both metric and standard (SAE) socket sizes, helping you select the right tool for the job․ You can also download a PDF chart․
Understanding Socket Sizes
Socket sizes refer to the measurement across the flats of a nut or bolt head․ Sockets are designed to fit snugly onto these fasteners, allowing you to apply torque with a wrench or ratchet․ Understanding socket sizes is crucial for efficient and safe work, preventing damage to both the fastener and your tools․
Sockets come in two main systems: metric and standard (SAE)․ Metric sockets are measured in millimeters (mm), while standard sockets are measured in inches․ It’s important to use the correct socket size for the corresponding fastener to avoid slippage and rounding of the edges, which can make the fastener difficult or impossible to remove․
Socket sets typically include a range of sizes to accommodate various applications․ The drive size of a socket, such as 1/4″, 3/8″, or 1/2″, refers to the size of the square opening that connects to the wrench or ratchet․ Different drive sizes are designed for different torque ranges, with larger drive sizes being used for heavier-duty applications․
Choosing the right socket size involves identifying whether the fastener is metric or standard and then selecting the socket that matches the fastener’s dimensions․ Using a socket size chart can greatly simplify this process, providing a quick reference for matching socket sizes to fastener sizes․

SAE to Metric Conversion Chart
A SAE to Metric conversion chart is a vital tool for easily converting between standard (SAE) and metric socket sizes․ This chart simplifies identifying equivalent sizes, ensuring compatibility and preventing damage to fasteners during projects;
Using the Conversion Chart
To effectively use an SAE to Metric conversion chart, begin by locating the known size – either SAE (standard) or metric – in the appropriate column․ Once found, simply read across the row to identify the corresponding size in the opposite measurement system․ This direct comparison allows for quick and accurate conversions, preventing the use of incorrect socket sizes․ For example, if you have a bolt head that measures 1/2 inch (SAE), find “1/2” in the SAE column and then look across to the metric column to find the equivalent metric size, which would be approximately 13mm; Similarly, if you know you need a 10mm socket, find “10mm” in the metric column and read across to see the closest SAE equivalent, which is roughly 3/8 inch․ Note that some sizes are only approximate equivalents, and the chart may also provide the decimal inch equivalent for greater precision․ Always double-check the fit to ensure you’ve selected the right socket, as forcing an ill-fitting socket can damage both the fastener and your tools․ Many charts also include additional information, such as tap drill sizes or hex key sizes, making them even more versatile․ For convenience, it’s a good idea to keep a printed copy of the conversion chart readily available in your workspace, or to have a digital version saved on your devices for quick access․ This simple step can save time and prevent frustration during any project involving both SAE and metric measurements․
