A Torque Wrench can be defined as the tool that is used to apply torque and fasten nut and bolts. This tool comes in the form of a socket wrench and features internal mechanisms. Conrad Bahr invented these in 1918 to prevent the over-tightening of bold on water pipes. These wrenches share similar mechanisms with Torque Screwdrivers. These Wrenches also help the user to measure torque needed to fasten the bolt or nuts without over tightening them.

What is a Torque Wrench – Why you need it?
The simplest idea that trickles into DIY minds is ‘Why not use the same torque value on every fastener that is of a particular size? A shop manual, really? Just to tell us that a valve cover held down by a 5⁄16-inch bolt requires a 11 ft-lb torque, and that a stud of the same measure sitting on the shock absorber demands 20 ft-lb?’ You can almost see how high their eyebrows have gone. Listen up, DIY-ers.
- Inclined wedges or planes help you turn bolts and nuts into place. These grooves are called threads.
- As you turn the nut or bolt along these threads you are veritably applying force along them; the bolt therefore acts like a tension spring.
- The bolt shank tension helps clamp two components into one.
- If this clamping force exceeds the load exertion between, say, the block and the head the pieces will never get loose of their own accord; this is a good thing.
- What is clamping force? It is how much twisting force you are putting on the nut or bolt head.
The DIY-er raises his chin and says, ‘So, yeah, you’re right about all that. Tighten till it won’t come loose. That’s it. Why make it sound so complicated?’
No, no, and no. The ideal amount of torque you need to apply is determined by these factors:
- If a gasket is present between ther two components
- Differences in total bolt length
- The bolt’s alloy type
- What material the clamped parts are made of
- The amount of friction being applied between the threads. This last point is a crucial one, it determines the link between the torque application on the bolt head and the clamping force needed for the job.
From as little as a few percent to over fifty, different friction levels determine how much force you need to apply during tightening. Doing it just right can save you a lot of hassle. Ths is where your brains come in and sheer strength can end up being a bad thing.
You can therefore certainly expect variations in clamping force. Too many differences can be a bad thing, especially for intake manifold and cylinder installations.
Use the right torque wrench, apply the right torque amount (ft-lb), and pay attention to friction and clamping factors.
How Reviews Help With Torque Wrench Usage
You cannot hope to find the best torque wrench for your needs if you do not know how to properly use one. Sooner or later the wrench you buy because someone said so or a review insisted it will resolve all your problems will lose its importance as one of the top tools for use in your garage or workshop.
In this spirit, let us broach a crucial topic where so many DIY users go wrong, namely applying the right amount of pressure using a torque wrench. Lug nuts are quite a common automotive repair element; you will come across these a lot during car and bike repairs and maintenance.
There is more to reviewing than merely telling readers which torque is best; we will leave that to the brand manufacturers. We also share facts and techniques on how best to use your selected wrench. That said, how do you tighten lug nuts properly and ensure maximum safety and quality of workmanship?
To get the ideal tightening level needed with your torque wrench, you must reach the ideal torque value for your vehicle (this is often measured in foot-pounds). Each fastener on, say, your car will require the same torque level.
How do you know when to stop? You cannot possibly be thinking about the torque level all the time, especially if you are a DIY-person. Here is an example:
- Suppose you apply ten pounds of force on the handle as you press down on a nut using a one-foot long torque wrench. You are veritably going at the nut using a ten foot-pound torque (this is basically distance x force or in this case 1 x 10 = 10).
- If you happen to apply 60 pounds of force using a 4-foot wrench, you will be applying a torque of 240 foot-pounds (60 x 4 =240).
- Bear in mind that most torque wrench for lug nuts display a 100 foot-pound torque requirement. It is as much elbow grease as what the wrench is performing, so it depends on how much cranking you are willing to dole out.
- Your aim is not to over-tighten a fastener but to keep it within a narrow range. Do not be surprised if a bolt or nut automatically unscrews after a while on the road. This is if they are too loose. Despite it all, if they still manage to hold on to their position you can expect leakage from the O-ring clamped there or the gasket even.
- If, on the other hand, you tighten them too much the parts that are bolted may be damaged, warped, or compressed. If the threads strip or the bolt shank shatters, you will lose all clamping force and the fastener is as good as useless.
The fastener is the best tool for a tightening job but you will be surprised how often people forget the basics, assuming that mere force alone will get the job done. It is not about strength alone, we have brains for a reason.
How To Find The Best Torque Wrenches Online
In this section, we are going to share with you a motley mix of useful information on how you can find the best torque wrenches online.
There are currently four different kinds of sizes for torque wrenches.
- Cars do well with 1/2-inch drive torque wrenches. The same applies to moderately big equipement and automotive repairs, not to mention SUV’s and trucks. You can find some inch pound torque wrench in here.
- If your projects involve small bolts and nuts, a 1/4-inch drive is ideal. Small torque applications like with this wrench are best for garden and lawn gear as well as motorbikes and bicycles.
- Overly heavy equipment and machines demand the use of a 1-inch drive torque wrench. Such machines include passenger airlines, tractor-trailers, marine equipment, and cargo aircraft.
- Light trucks and cars, among general passenger vehicles, are great with our final wrench size, namely a 3/8-inch drive.
Learning from the user experience, suppose you want to perform tire and/or engine work and you are confused about whether to use a ½-inch or 3/8-inch wrench. You can start with a ½-inch torque wrench with 30-150 and take it to your lug nuts.
The range has to be maintained around the middle because the bottom and top limits of the 30-150 ft-lb range are not as accurate. Using that value to fasten, say, 30 ft-lbs can result in your torque being off by 7%, which can be a good or terrible one. Apparently with torque wrenches, size does matter.
Types of torque wrench
When selecting a precision tool of this caliber and type, make sure you can use the one you want to apply the needed tension, load, or force to threaded fasteners; this is usually during assembly time.
Since you are most probably going to shop for a torque wrench online, bear in mind that you cannot skimp on accuracy and quality when it comes to torquing. After all, a machine has to hold under vibrational pressure not to mention general operation rigors. Good torque equals long-term efficiency and adequate component tightening.
- Beam Torque Wrenches
One of the more simple wrenches out there, its design comprises a lever arm separating the handle and head. Thanks to its elasticity, the arm can actually bend against the pressure being applied to it. Do not worry, this is a good thing. If the wrench is inactive or there is no pressure, the arm and indicator remain parallel to each other. You can use the scale to get a reading during work; it looks and performs like a weight scale with a needle pointer.
- Deflecting Beam Torque Wrenches
With this one, you do away with the coil spring method of applying torque and rather go for the deflecting beam technique; hence the name. Aside from promoting enhanced safety for higher torque levels, you also gain better precision. A distinct click can be heard when a certain torque level has been attained. This is one of the more smart torque wrenches out there.
- Electronic Torque Wrenches
Not only can you program these, they also have pre-set limits. Linked to the torsion rod is a strain gauge. By signaling the transducer whenever needed, this feature helps determine torque force per unti. An LED readout shows you the value. You also have a tiny chip equipped with a memory stick to save all readings that are consequently open for computer access. How convenient is this.
- Plumber’s Torque Wrenches
Solely for soil pipe and coupling use, this specialized wrench looks rather like a ratchet in that it has a T-shaped handle. Thanks to its pre-calibrations, though, it can slip back when the required torque strength is reached. As the name suggests, this wrench is best used by plumbers.
- Click Torque Wrenches
A bit more sophisticated than the socket wrench whose design this one is based on, click wrenches let you use a clutch mechanisms to pre-set torque levels that when reached causes the clutch to slip by way of indication. As you can imagine, this is quite an accurate tool and prevents over-stretching or breakage.
- Hydraulic Torque Wrenches
Especially made for torque applications to fasteners, you can use this one to place pressure on bolt or nut heads. Because the torque can be pre-calibrated, you can quickly get started with tightening. Just make sure the bolts and nuts are ideally lubricated. After all, this wrench is used for heavy-set automobiles where plenty of power and pressure are called for.
Thanks to the idea of square drive technology, rotors can expand outwards or inwards and display heightened functionality no matter the load or speed involved. In addition to improving rotor lifespan, square drives help avoid failures due to distortion.
Here is a table with ideal square drive recommendations for varied torque wrenches.
The primary reason you are using a torque wrench is to apply an accurate or exact torque to a fastener. This includes a bolt or nut. By applying the wrong amount of torque, you can experience mechanical failures, loose fasteners, warped material, rattling, and other issues that will prove dangerous for the machine or vehicle you are working with.
Measured in foot-pounds (ft-lbs) or Newton-meters (NM), this range tells you the minimum and maximum torque that can be applied to something from a particular torque wrench. For instance, light work to do with fastening or tightening will find a 15-75 ft-lb range more than enough for the job.
An operating range comprising maximum and minimum values is termed range, and you should never stick to the extremes. Calibration can be severely affected if you do not find a balance at the middle of the range; the wrench’s precision will drop as well. When it comes to range, do not surprised if you find yourself using different wrenches for one task or project; one range does not fit all.
- As mentioned above, the 15-75 ft-lb range is ideal for light duty work as seen with valve cover bolts, oil drain plugs, and cover for spark plugs. This is the low range.
- Still in the low range category is a 30-150 ft-lb range that is best for slightly heavier work as with tightening head bolts, caliper bolts, and lug nuts. It is imperative that you have a torque wrench with this particular range, because of how simple it makes the transition from maintenance to high-end upgrades and repairs.
- The mid-range comprises 50-250 ft-lbs and is great for all critical assemblies from suspension to steering. Trailers and lightweight trucks make excellent use of this range.
- Heavy and grand equipment and machines where driveline components and bearings need ace tightening do well with the upper range of 120-600 ft-lbs.
- Even here you have a 200-1000 ft-lb range that is applied to camshaft sprockets and harmonic balancers. In other words, the bigger end of the upper range is multifunctional and used in racing vehicles; maintenance and repair.
