What’s the Equivalent of a 14mm Socket?

Socket wrenches are essential tools in a variety of industries, from automotive repair to home improvement. One of the most important aspects of using socket wrenches is understanding socket sizes and their equivalents. In this article, we will focus on the 14mm socket size and explore its applications, equivalents, and common uses.

Understanding Socket Sizes

Socket sizes play a critical role in the world of tightening and loosening. They allow for a precise and secure fit between the socket and the corresponding fastener, ensuring efficient and effective work. Here are some key points to consider when it comes to understanding socket sizes:

Metric and Imperial:
Socket sizes are primarily divided into two systems: the metric system and the imperial (or SAE) system. The metric system is widely used throughout the world and measures socket sizes in millimeters (mm). The imperial system, used in the United States and a few other countries, measures socket sizes in fractions of an inch.

Metric socket sizes:
Metric socket sizes are identified by their inside diameter, which is measured in millimeters. Sizes typically range from as small as 4mm to as large as 36mm, with smaller increments between sizes in the smaller range and larger increments in the larger range. Common metric socket sizes include 6mm, 8mm, 10mm, 12mm, 14mm, 17mm, 19mm, and 22mm.

Imperial Socket Sizes:
Imperial socket sizes are measured in fractions of an inch. Common imperial socket sizes include 1/4-inch, 3/8-inch, 1/2-inch, 5/8-inch, 3/4-inch, 7/8-inch, and 1-inch. These sizes also follow a gradual increment pattern, with smaller increments in the smaller sizes and larger increments in the larger sizes.

While it is generally recommended to use the exact socket size for a particular fastener, there are instances where interchangeability is possible. This is especially true when there is a slight difference between the required socket size and the available socket sizes in your set. In such cases, you can use a socket that is slightly smaller or larger than the specified size as long as it provides a snug and secure fit on the fastener.

However, it is important to use caution when using alternative socket sizes. Using a socket that is too small may result in rounding of the fastener or damage to the socket itself. On the other hand, using a socket that is too large may not provide a secure grip, resulting in slippage or stripping of the fastener.

Special Socket Sizes:
In addition to standard metric and imperial sizes, there are also specialty socket sizes designed for specific applications. These may include extra-large sockets for industrial machinery, special sockets for specific automotive components, or sockets with unique shapes or features for special tasks.

It is important to have a comprehensive socket set that covers a wide range of sizes to ensure you are prepared for a variety of fastening and loosening tasks. A well-equipped socket set will allow you to tackle a wide range of projects, from automotive repairs and home maintenance to industrial applications.

Equivalent Socket Sizes

While it is important to have a socket set that covers a wide range of sizes, it is not always practical or convenient to have each individual socket size. In certain situations, you may need to find an alternative socket size that can be used interchangeably with a 14mm socket. While it is generally recommended to use the exact size whenever possible, there are some close equivalents that can be used in a pinch. Some common alternatives to a 14mm socket include

  • 9/16-inch socket: The 9/16″ socket is slightly larger than the 14mm socket, but the difference is minimal. In many cases, a 9/16″ socket can be used as a replacement for a 14mm socket, especially in applications where precision is not critical.
  • 19/32-inch socket: Another close equivalent to the 14mm socket is the 19/32-inch socket. This size is slightly larger than the 14mm socket, but can often be used interchangeably in certain situations.
  • 23/32-inch socket: Although the 23/32-inch socket is larger than the 14mm socket, there are times when it can be used as a replacement. However, it is important to exercise caution and ensure a proper fit, as the size difference can affect the performance and safety of the tightening or loosening process.

Common applications

The 14mm socket size is widely used in various industries and applications. Some common applications include

  • Automotive repair: The 14mm socket is often used for tasks such as removing or installing spark plugs, manifold bolts and certain engine components.
  • Plumbing: In plumbing applications, the 14mm socket can be used to work with pipe fittings, valves and fasteners commonly found in plumbing systems.
  • General maintenance and DIY projects: The versatility of the 14mm socket makes it a valuable tool for general maintenance and DIY projects such as furniture assembly, appliance repair or equipment maintenance.


Understanding socket sizes and their equivalents is essential for anyone working with socket wrenches. While a 14mm socket is a standard size with numerous applications, there are close equivalents that can be used in certain situations. However, it is important to exercise caution and ensure proper fit when using alternative socket sizes. Remember, using the correct socket size is critical to the safety and effectiveness of any tightening or loosening application.


What is a 14mm socket equivalent to?

A 14mm socket is equivalent to almost 9/16″ in size. It is the closest size to a 14mm metric head. The closest size wrench to 14mm is metric/standard wrench conversion chart lists 9/16″ as the size. The closest size bolt to a 9/16 wrench is hex, lag, square, and heavy hex. Arranging or sorting your sockets based on the size may sound easy. But it is not. Especially when there are two measurement standards, SAE and metric, which you need to keep in mind. You can think of a drive socket as the hole (square) for attaching the socket to a turning tool like a wrench or a ratchet. The most common drive sizes are 1/2″, 3/8″, and 1/4″. Impact sockets are specially designed to fit in such tools. You can use the metric socket sizes chart and SAE socket sizes chart to easily convert between US inches and metric mm wrench and spanner sizes.
