It is hard to imagine a mechanic without sockets in their toolbox. Whether they are chrome sockets or impact sockets, both are must-have tools in any professional garage or workshop. Do you know how they were designed and how they evolved over the years? You will find these answers in this blog.

History of Sockets 

 

J. J. Richardson was the inventor of the first “ratcheting wrenches” (also known as ratchets and socket wrenches) to use with interchangeable sockets. The patent was granted in 1863 and the first illustration of this socket wrench appeared with two different sizes of interchangeable square sockets in a 1864 issue of Scientific American.

The invention of the ratchet was revolutionary for mechanics; no longer was it required to painstakingly install and remove nuts and bolts with a traditional wrench, but mechanics could now make quick work of their nuts and bolts with a efficient back-and-forth ratcheting motion thanks to the innovative socket wrench.

Modern-Day Sockets

 

Without a doubt, sockets and socket wrenches are two of the most important tools for a mechanic. There are many types of sockets in the market ranging from shallow to deep, 6 pt or 12-pt, as well as many other shapes, sizes, and features!

Sockets typically come in two different unit systems: metric sockets in millimeters and SAE sockets in imperial units (inches and fractions). However, there are also many specialty sockets such as E-Torx, triple square, and bit sockets. 

Metric fasteners are typically found on European and Japanese vehicles with imperial (SAE) sizes being more prevalent in American-made vehicles. However, with more globally sourced parts and more standardization, it’s not uncommon to find both standards used in a single vehicle. Because Metric and SAE sockets are not perfectly interchangeable, and using the wrong size socket on a nut or bolt could damage the fastener head, most mechanics find themselves owning both Metric and SAE sockets. 

Sockets are a must-have tool. With the variety of shapes, sizes, and features available at Olsa Tools, you can find one that will make your job easier.

Common Types of Sockets

Below are some of the most common types of sockets, each designed for specific applications to help you work more efficiently and safely.

• Standard sockets: Commonly used for general fastening tasks, available in both metric and SAE sizes.
• Deep sockets: Designed for reaching fasteners in recessed areas, providing additional clearance for long bolts. If you need deep sockets, check out our impact swivel socket set, it comes with shallow and deep socket varieties.
• Impact sockets: Made of thicker, more durable material to withstand the high torque of impact wrenches.
• Impact swivel sockets: Feature a pivoting head that allows access to fasteners at difficult angles while enduring high torque.
• Torx sockets: Specifically designed to fit Torx (star-shaped) fasteners, commonly used in automotive and machinery.
• Hex bit sockets: Used to fasten or loosen bolts and screws with hex heads, ideal for precision applications.
• Spark plug sockets: Equipped with a rubber insert to grip and remove spark plugs without damaging them.
• Universal joint sockets: Provide flexibility and allow access to fasteners at various angles in tight spaces.
• Pass-through sockets: Designed to work with threaded rods, allowing the fastener to pass through the socket.
