Socket Size Chart report

Using a wrench can be accessible when you need to tackle jobs in your home. However, you can quickly overload your portable workbench when you have many varying sizes to work on. Arranging or sorting your sockets based on the size may sound easy. But it is not. Choosing socket sets that display all the sockets in order from smallest to largest is not the whole story, especially when you need to consider two measurement standards, SAE and metric.

Whether a mechanic or a homeowner, having a socket set is crucial. A socket set is very helpful whenever you need to deal with nuts and bolts. A good socket set gives you all the sizes necessary.

The following post will introduce all you need to know to ensure you are using the right socket wrench sizes and have the correct drive size to match.

Socket Size Guide

Sockets are generally used to tighten or loosen different fasteners. They can be an alternative to the conventional wrench if you know their usage. Working with slippery sockets of the right size gives an excellent grip. It gives you a smooth experience and prevents injuries of any sort. Most DIY enthusiasts and mechanics prefer having a set handy.

Sockets follow two different sizes. There are two different methods for measuring socket size. The SAE (Society of Automotive Engineers) system uses inches, and the imperial or metric system uses millimeters. Knowing about both is important if you need to use your sockets regularly. Below, you will find the necessary sockets, types, and sizes. You will also find a detailed chart for easy conversion.

Most Common Socket Drive Sizes

The drive is the central part of the socket. The hole where the socket is attached to a turning tool, like a wrench or a ratchet. The type of drive depends on the task at hand. You tend to find the following three standard sizes, although others are available.

• 1/4" Drives: You find these used for low-torque work and are usually for smaller-sized sockets, possibly up to around 14mm as a maximum. They are very useful, especially if working with small parts, such as fixing a broken valve.
• 3/8" Drives: The most common category of drives available is the 3/8" drives. They are common in most socket sizes.
• 1/2" Drives: The largest drive available is the 1/2" drive. Usually used for more substantial jobs on vehicles where the nuts are more substantial and need more torque. You'd see these drives in 19mm socket sizes often. They are generally used in mounting TVs or fixing shower vents.

Metric Socket Sizes Chart

The most common size chart for sockets is the metric size. They're used all over the world, minus a few exceptions. These are the sizes for sockets in the metric system.

SAE Socket Sizes Chart

The SAE measurement system is slightly complicated. It’s used more prominently in the USA and nearby regions. The SAE size chart is shown below:

SAE to Metric Conversion Chart

Both the SAE and Metric charts are pretty common, knowing both is crucial for you. The below chart will help you convert the socket dimensions from SAE to Metric.

If you lack a clear understanding of socket sizing, its easy to choose the wrong tool. Without a tool of the correct size, you won't be able to properly fix or lock the nut. You will find the above size charts more useful than you think.
