Ratchets: What You Need to Know
Whether you’re working on a car, other piece of machinery or taking on a building project, a ratchet is an essential tool. Commonly used for fastening nuts and bolts, there are a few different types of ratchets available. Here are some important things to note:
Types of Sockets
Sockets connect to your ratchet to help you make adjustments quickly and easily. Depending on the job at hand, you’ll need a certain type of socket. Here’s a breakdown of the most common socket types you’ll find and when you’ll likely use them:
Socket Length and Special Features
Not every socket will work for every job, even if it’s the right size. If you’re working in a tight space or on a very difficult project, you may need a special socket length or type to get your job done efficiently. Some special features also make working with ratchets and sockets easier.
What does a quick release ratchet mean?
Well, basically it means that you can quickly remove the socket that’s attached to the ratchet by pressing that button.
What is the difference between a pear head and a round head ratchet?
The style of ratchet also dictates how the ratchet switches direction, with pear-head ratchets often having a small selector switch near the base of the head and round-head ratchets building the switch directly into the back, often as a knob. Round-head ratchets also tend to be bulkier than pear-head counterparts.
What are the two styles of ratchets?
The head shape also often dictates the type of mechanism that’s responsible for doing the ratcheting. The two main styles of ratchets are round head and pear head.
What is a roto head ratchet?
These are essentially round-head ratchets, or palm ratchets, affixed to a ratchet in a way that gives you a 270-degree rotation of the drive. These are bulky, but they come in handy when you can use them.
How does a ratchet count work?
A ratchet’s tooth count references how many teeth are on the drive gear, which translates to how far you need to move the handle to engage the next tooth. As manufacturing has progressed, and as space to work in a car has shrunk, ratchet tooth counts have gotten higher. That’s good news! The higher the tooth count, the less the handle has to move to engage the next tooth. That means if you’re in a tight situation you’ll be able to take things apart that you might not be able to with a ratchet that has a larger swing arc.
How many teeth does a ratchet have?
Fine, or high-tooth-count, ratchets range from about 72 teeth to 160 teeth. Now, tool manufacturers can create these high-tooth-count ratchets a few different ways. You can obviously machine more teeth onto the drive gear or you can add more pawls.
What are the different lengths of ratchets?
Ratchets generally come in three different lengths: stubby, standard and long . There are also extra-long ratchets for those who really need the added oomph to take something apart but don’t have the space to step up to a bigger drive size or use a power tool. As you can imagine, the ratchet’s length has a direct relationship to how much power you can apply with it: The longer the handle, the more torque. The downside: Longer handles don’t play well in cramped quarters. Tight places are where stubby ratchets thrive. You also won’t generally run into highly torqued fasteners in places where you’ll want to use a stubby ratchet, so the loss of leverage isn’t as big of a deal.
