Why Do You Need a Ratchet Wrench?

Ratchet Wrench


A ratchet wrench is used to tighten and loosen nuts and bolts. The ratchet mechanism lets it exert undo the nut only in one direction - meaning that you can quickly undo or tighten nuts without having to constantly lift the ratchet off, as you would with a traditional spanner. The reverse movements are very efficient and require little or no adjustment at all. On the other hand, it allows you to use the tools very effectively even in cramped out spaces like car engines and other areas where you need every delicate and efficient usage. And the most important thing about these wrenches is that they can easily be used in tight corners and narrow spaces with the least bit of effort. In addition, it could apply with an extender arm, a few adopters, and removable joints that help you work with all kinds of nuts and bolts regardless of size.


Drive Sizes

All ratchets accept sockets using a square drive and mostly there are 3 most commonly used drive sizes that you can find in the market. Everywhere in the world drive sizes are likely given in inches.
● 1/4 inch - Used for smaller sockets and precision work. Useful for dismantling individual components on the bench.
● 3/8 inch - The middle-sized, and in my opinion, the most useful size for general use in a car. A 3/8" drive can drive sockets of all sizes. It is big enough to apply quite a lot of force, but not too big to fit into tight spaces
● 1/2 inch - 1/2" sockets are generally used for nuts and bolts from around 10mm and up. A 1/2" drive socket can apply enough force to undo all nuts on a car.


Tooth count

Inside a ratchet, there is a toothed wheel that lets it freely rotate as you tighten the socket. Each click you hear is a tooth passing the ratchet. The more teeth there are, the less movement is needed on the return stroke. A ratchet with 72 teeth will work considerably faster than a 36 teeth ratchet. Making high tooth counts requires quality engineering and manufacturing. So it’s considered that better quality tools will have a higher tooth count.
Whenever you are getting a ratchet wrench make sure that you invest in a high-quality tool that can offer you long periods of usage without any difficulties.
