The 3/8 Torque Wrench is one of the most common ratchet drives. I think every mechanic that works on vehicles will have one, as it's an essential tool in any garage. It's not often you'll come across a device that performs so many duties. The 3/8 torque wrench has two jaw units, which are in turn driven by a spring. This unique feature helps to make sure that you get proper tightening and very little loosening.
It is easy to see how the 3/8 torque wrenches have become so popular, and they're so versatile and user-friendly. Almost every vehicle that can be driven on the road has one, from cars, trucks, SUVs, tractors, and boats, to you name it. Even mechanics and car enthusiasts have them because of the benefits these ratchet-type torque wrenches provide. Everyone knows that a dirty engine causes a dirty ride, and over time, this can lead to major problems. You can't just put a new plugin on an old engine; you have to take it apart and clean it first. This can become very difficult and dangerous if things go wrong.
When working on a car, it's always important to know the weight of each part and its corresponding size. With a 3/8 torque wrench, you can easily determine this and ensure you use the right size parts for the job at hand. You don't want to tighten or loosen something without knowing its size, as this can cause damage to other critical parts. If you don't use the right size socket, then the whole thing could fail. It's best to use the right-sized socket and torque wrench to avoid these issues.
If you're using a larger scale 3/8 torque wrench, then you know they come in different sizes. The advantage to these larger-scale wrenches is that they often come with a square drive feature. Square drives are very strong and can make long and hard drives much easier to complete.
However, this square drive feature comes with a trade-off. It can be difficult to tighten bolts that are close in size. This can become frustrating when you've spent a lot of time tightening your bolts, but the bolt slips through easily because the teeth of the torque wrench are square. To fix this, you need to apply some lubrication to keep the teeth square as you tighten the bolt.
Larger torque wrenches often come in both metric and standard sizes. Metric bolts tend to be stiffer and require a different method of securing them down. These types of bolts are also more expensive because they are made out of different metals. Many hardware stores stock metric bolts and even offer them in standard sizes.
Some metric-type tools have ratchets. A ratchet is basically a combination wrench. It has features that include both a standard and metric drive. You can get ratchets in a wide range of sizes, and you will be able to use them for different types of installations. For instance, you can get a ratchet that measures torque from one-half to three-eighths of an inch.
