When working on a car, boat or plane, bolts usually come in two different types. The first one is the regular bolt. The bolt you can tighten up with a regular ratchet and your bare hands. It doesn’t really matter how hard you tighten it as long as it’s tightened.
The second type is a little fancier. These bolts require to be tightened to a specific torque. The most common example of this would be the engine head and exhaust manifold bolts. They are under constant stress and you can’t risk having them loosen up.
You absolutely need to tighten them to a specific torque using the best torque wrench you can find or you may end up having to pay for expensive repairs.

This is actually one of the torque wrenches I use every day on the job. I bought it maybe 4 years ago and it’s working like new. I even had it tested last year and the calibration was still on point! After all, isn’t accuracy the most important factor when buying a torque wrench?
What To Look Out For When Buying A Torque Wrench?
When on the hunt to find the best torque wrench possible, a number of factors are to be considered correctly select on that will fit your needs.
What’s your budget?
First, you need to establish your budget. Some torque wrenches are quite inexpensive while others can cost a huge amount of money depending on the overall quality, accuracy, size, and the number of options they may come with. The trick here is to find one that will give you the most bang for your buck based on the tasks you intend to use it for.
Always take a minute to think about what you may do with the tool.
Bigger and longer torque wrenches provide greater leverage but they won’t always fit where you need them to. Smaller ones can be used in tighter spots but the measuring range is often a lot lower.
If you work in a low-light environment, you may need one with a lighted display or one emitting a buzzing signal when the target torque is reached.
Mechanics working on V-type engines may need a torque wrench equipped with a flex head while small engine mechanics don’t.
Digital or Analog?
Whether you prefer analog or digital torque wrenches is mostly a matter of taste.
Digital ones may be a little more accurate because it’s easier to adjust the torque setting down to the decimals but electronic systems may not be as reliable in the long term.
Analog models, on the other hand, are built using nothing more than metal so they usually last longer than digitals. They don’t require the use of batteries, eliminating the risk of having to find new coin batteries every time you want to torque something.
Digital torque wrenches often offer peak and trace modes to keep track of what you are doing in real-time. Analog models simply can’t do that.
There’s a big difference between all-steel and chrome-vanadium torque wrenches. All-steel models are typically less expensive but they are also heavier, bulkier and the handle may sometimes crack under pressure after a couple of years. Chrome-vanadium ones are usually more expensive but they are lighter, thinner and will last longer than steel models. It really depends on the frequency you may use your torque wrench.
All-steel models are perfect for weekend DIYers and backyard mechanics. They are quite inexpensive and will do the job just fine. Chrome-vanadium ones are mostly designed for professional use or regular intensive work.
Accuracy may or may not be an important factor. If you mainly use it to torque lug nuts to 90ft./lb., pretty much any torque wrench will do. However, when you need to torque engine head bolts, an inaccurate tightening procedure may stretch the bolts more than required.
This weakens them and leads to costly repairs in the future. Mechanics working in the aviation industry are required to use torques wrenches calibrated following specific national standard certification.
Most common torque wrenches usually have a measuring range from 10 to 250 ft./lb. and that should be more than enough for most applications. Typical exhaust manifold bolts only require to be torqued to something around 20ft./lb.
Car lug nuts only need to be tightened to 90-110 ft./lb. and 150 ft./lb. for engine head bolts. Big rig mechanics will need to get their hands on a much bigger torque wrench since commercial truck wheels sometimes require a torque setting of over 600 ft./lb.
In the end, the winner of the “Best Torque Wrench of 2021” title is definitely the GearWrench 85077 digital model. The unusual but cleverly designed teardrop sealed head makes it last longer than any other on the list and the 5-degree arc swing simply leaves common torque wrenches in the dust.
It works and measures torque in both directions as well as offering a convenient Peak and Trace function for approximately the same price tag as its competitors. With a longer lifespan and more features than most, the GearWrench 85077 is really a no-brainer.
