What are socket sets used for?

Socket sets offer a comprehensive selection of socket wrenches, allowing you to quickly and easily tighten or loosen fasteners of all sizes and types. They are available in imperial or metric sizes, and the most inclusive ones often offer both options. Multi-piece sockets include ratchets, regular and deep sockets, adaptors, and joints.

Smaller sets are ideal for simple everyday tasks, while a large set can offer additional deep sockets and multiple drive sizes.

This buying guide informs you of the different types of sockets available, their usage and features and introduces you to the best socket sets available.

In the end, you will have the knowledge and expertise to tackle any project that comes your way.

Most common socket set components:

• Ratchet
• Universal Socket
• Pass-Through Socket
• Driver Socket
• Spark Plug Socket
• Impact Socket
• Socket Adaptor
• U-Joint Adapter
• Socket/Ratchet Extension Bar
• Torque Wrench
• Joint

Socket Types

Chrome Plated Non-Impact Sockets

The most common socket available on the market is the chrome-plated non-impact socket. The chromium-vanadium steel it is made of undergoes a heat treatment process that grants it extreme hardness. These sockets have thin walls, making it easy to work in narrow spaces when applying hand torque.

These sockets are best used for auto repairs, household jobs and outdoor projects involving non-powered hand-driven jobs. You should avoid using non-impact sockets with an impact wrench, as the increased torque can easily shatter the socket.

Impact Sockets

Impact sockets are used for heavy-duty jobs requiring air or power tools. They have thicker walls, are finished in black phosphate or black oxide to withstand higher torque, and have a pliable steel composition. Thanks to the cross hole in the handle end, impact sockets can be securely attached to the square drive of an impact gun.

Universal Sockets

A universal socket offers extreme DIY versatility. Its shape resembles a standard deep socket but with many small metal pins in its head. These pins make the socket compatible with various fasteners, perfect for smaller jobs or tasks requiring multiple fastener types.

Driver Socket

Driver sockets are screwdriver-bit fasteners. The most common ones include flathead, Phillips, hex or star-head screws.

Spark Plug Sockets

As the name suggests, this socket type is most commonly used in the automotive industry. It is a deep socket designed to fit over the body of a spark plug in a spark-ignition engine.

This socket is lined with a rubber insert that grips the spark plug, allowing you to pull the plug out once loosened.

Socket Adaptor

Socket adaptors allow you to fit a socket to a ratchet handle with a different size (drive adaptors) or shape (hex-shank adaptors).

U-Joint Adapter

A U-joint adapter is an accessory that allows you to connect a socket to a ratchet and use it at different angles relative to the fasteners.

Pass-Through Socket

You can use a pass-through socket to turn a nut on a longer, threaded bolt, allowing the bolt to extend through the socket and ratchet. If you have this socket type in your set, you do not need low-profile and deep sockets. However, pass-through sockets can work only with specifically designed ratchets.

Breaker Bar

Breaker Bars are long, non-ratcheting bars often used with sockets. Thanks to their extended handle, they provide greater torque with the same force applied. 

Extension Bar

An extension bar is an attachment between a socket and a ratchet to increase the reach of the socket and turn recessed fasteners.

All you need to know about Ratchet Wrenches

One of the most essential socket set pieces is the ratchet wrench. Ratchets come with three different drive sizes&#;1/4&#;, 1/2&#;, and 3/8&#;. The drive is the part of the ratchet where the socket is attached. Different drive sizes have various applications and specifications; thus, aligning the drive size with the job is essential.

Drive Size

1/4&#; Drive

A ¼&#; drive ratchet is perfect for small DIY projects, such as shelf assembly, stud attaching, or other low torque jobs. A ¼&#; drive will give you just enough torque for a job (no more than 78Nm). These are usually used for smaller-sized sockets (maximum 14mm).

3/8&#; Drive

A 3/8&#; drive ratchet withstands higher torque, and it is more versatile than the ¼&#; equivalent. Sockets with a 3/8&#; drive have thicker and more rigid sidewalls and can be used at home and in the workshop.

1/2&#; Drive

½&#; inch drive ratchets are used for heavy-duty jobs where you operate with big fasteners and require more force or torque. For example, when you replace a vehicle wheel or assemble heavy machinery. These drives are primarily used for 19mm sockets and above.

Gearless vs Geared Ratchet

Most ratchets operate with a geared drive mechanism that allows them to move only in one direction. This mechanism comprises a gear and a pawl (a type of latch consisting of a spring-loaded tapered lever pivoted at the end). The gear has asymmetrically shaped teeth, allowing it to move past the pawl only when it rotates in the desired direction, leading to a fixed swing amplitude.

In recent years, gearless ratchet models have also gained popularity. Gearless models don&#;t have a ratcheting mechanism inside them; instead, they have a roller bearing. Thus, these ratchets require fewer movements to turn fasteners than a geared drive.

Drive Shape

The most common socket drive shapes are hex and square. Owning a few socket drive shapes and sizes will allow you to tackle almost all standard fasteners in everyday jobs.

Ratchet Head

A ratchet&#;s head can be either fixed, flex or swivelled. Flexible-head ratchets let you adjust the handle&#;s angle to work in tight areas. However, flex-head ratchets are unsuitable for high-torque jobs as they add one more possible failure point to your tool.

Swivel-head ratchets are bulky, giving you a 270-degree rotation of the drive. They can easily switch from a ratchet to a nut driver to quickly remove fasteners.

In terms of shape, there are two main shapes of ratchet heads, round and pear.

Locking Mechanism

Some ratchets have locking mechanisms to keep the socket and the fastener in place without falling. Sometimes, this can be a small ball detent holding the socket or a push-button at the back of the ratchet head, allowing for locking and unlocking the mechanism.

There are also ratchets with a directional knob at the back, allowing you to change the direction whether you tighten or loosen the fastener.

FAQ

How do I know if a socket fits a particular fastener?

Sockets are designed to fit specific fastener sizes. Check the size markings on the socket and match them with the fastener size. For example, a 10mm socket fits a 10mm hexagonal fastener.

What should I look for in a high-quality socket set?

• Material Quality: Look for sets made from high-quality steel alloys for durability.
• Precision and Fit: Ensure sockets fit securely onto fasteners to avoid stripping.
• Durability: Check for features like corrosion resistance and impact resistance.

What is an impact socket, and how is it different from a regular socket?

Impact sockets are designed to handle the high-torque forces of impact wrenches. They are made from tougher materials, like chrome-molybdenum steel, and have thicker walls than regular sockets to withstand heavy impacts.

At Toolden, we offer various Socket Sets for domestic and commercial applications.

for $250 in 1/4 + 3/8 metric only you can buy any brand you want. Its really more about how many variations you want (deep, shallow, semi, swivels) and maybe how much coverage at that stage...do you need ratchets and drive tools as well? I wouldn't hesitate to mix brands a bit, either.

Without a doubt the best value is gearwerench sets for $100. There is also Toptul and Facom along with Napa/Carlyle...All of those are Taiwan coo and the quality is good to great and prices from dirt cheap to modestly expensive.

For coo conscious tools, I'd look at Proto first. There is also williams and wright and SK but that tend to be in sets and you'd have to like the ratchets.

Also, don't forget you can score some basic kits from german brands like stahlwille if you catch them on sale and just need shallows with drive tools.

If you need deep and universals, that will stretch your budget a bit and force you down into lower pricepoints because the number of pieces will double or triple. and the per-item cost will be also higher as those tools have more materials and time involved in the production.

I'd strongly consier the GW kit with deep/shallows in 1/4+3/8 dive and bogo universals. with whats left over, a snap on or maybe a couple of carlyle long ratchets -- if you need the more comprehensive type solution on that fixed budget.
