Top 10 Best Torque Wrench
All modern equipment –be it a car you drive, the motorcycle, the lawnmower, industrial equipment, even a bicycle– are engineered for performance, efficiency, and economy. The most precise way to hold it together is with bolts and nuts. Each bolt is designed to hold its share of the load and to keep it in precise alignment. It means that you cannot go on guessing how much to tighten the bolt or nut without risking sheering off a bolt, stripping its thread, or under-tightening a nut at which point it will become loose even just during normal operation.
In the things like wheel nuts and axle nuts (where nut clamping power responsible on properly loading a bearing), under-tightening or over-tightening will cause you very expensive repairs in the future.
Never mind that a brake caliper bolts responsible for your safe stopping on the road. Proper tightening, clamping, torquing is not open for interpretations anymore. It is exact science, and you need to pay attention too. Lucky for you, you stumbled upon my website.

Tohnichi Adjustable Torque Wrench QL50N
Tohnichi Adjustable Torque Wrench is purely metric tool. It is best to use when torque specified in Newton-meters. This way you don’t have any ambiguity, and assembler after good night out would not mix up the Nm with ft.lbs.
However though, the values are not approximate so they require precision. This torque wrench complemented well by his 40-200Nm brother: Tohnichi Adjustable Torque Wrench QL200N4.
Both these torque wrenches are for Clock Wise torqueing only. One of the best things about these wrenches, nice pronounced solid click.

- This is metric only
- The small convex window makes decimals hard to read
Capri Tools 31200 20-150
Capri Tools 31200 inch pound torque wrench has ¼” drive. Although this wrench is an industrial-level torque wrench, it has a solid tool for easy and certain adjustments. Drive selection is straightforward, and a ball-bearing bit holder button (instead of a friction bearing) is a nice feature. It’s high tooth count, which is handy when working in tight spaces, might find it handy to most auto mechanics. It’s designed for regular, daily use and long-term durability (Approved for up to 10,000 clicks at max torque without re-calibration.) It is also reversible (can tighten both clockwise and counter-clockwise.)
For best fit application use it for 40 – 135 in.lbs range. Don’t use it right at 150 in.lbs; the risk of overtightening something is great with the small tool.
- Accurate: less than +/- 3% CW, and +/-5% CCW
- All metal construction
- Well designed and suitable for industrial applications where ISO standards call for NIST traceability
- Socket release button is great, and needed for small size torque wrenches
- Micrometer positive lock ring for secure locking mechanism
- Some people like tools to be shiny, not satin finish
- Again, some people find the scale hard to read
Important Torque Formula & Equation Tables
Using a torque wrench will be useless until you know the torque units and values you need to torque the nuts and bolts to. Here are the tables to take the guess work out of most commonly used fasteners. When it comes to intricately engineered and precisely designed parts, or components, you need to consult the repair manuals and assembly instructions.
For example, many engine manufacturers use single use bolts that are designed to Torqued-To-Yield (TTY). In that case, you torque with this wrench, then you turn the bolt X degrees more. Those are designed to utilize the clamping force of the bolt when it is overstretched. There are tools for that as well, and it will be covered on our Advanced Torque Wrenches guide.
Proper Handling and Care
You need to select the right torque wrench for the application. There are few things one needs to pay attention to, and it is very important to use the tool properly and handle it with care.
- Choose a torque wrench that has your specified torque value from 20% to 90% of torque wrench full scale. This will ensure the most precise torqueing in your application.
- Don’t throw or drop a torque wrench. Impact of the tool on a hard surface can throw off its calibration. If the calibration is off, you will not get specified torque value that you need to achieve.
- Use a torque wrench only at the end of the final assembly. Unless you doing forensic disassembly, don’t use it as the primary mean of removing nuts or bolts. When you use torque wrench for removing nuts or bolts, make sure it is rated for CCW, and torque value spec is 40% to 60% of the torque wrench full scale. Use appropriate tools for initial fastening as that could damage it and cause it to need recalibrating sooner.
- Use appropriate tools for initial fastening. The use of torque wrench in initial step could damage it and cause it to need re-calibrating sooner.
- Apply torque wrench in a controlled, smooth, and methodical manner. Fast or jerky movements can result to inconsistent and inaccurate torquing. It can also damage it.
- When storing a click-type torque wrench, set it to the manufacturer recommended setting. If the setting is not specified, set it to the lowest value on the scale.
- Most torque wrenches are length specific so always grasp the wrench in the center of the handle. If two hands are needed, place one hand on top of the other. Sometimes, when the socket extension is used, support the torque wrench at the pivot point.
- Recalibrate a torque wrench when a certain amount of time or number of cycles have been reached as specified by the manufacturer, or sooner if it have been mishandled or dropped.
- Never use cheater bars or handle extensions unless they are allowed by the manufacturer.
- Store your snap on torque wrench in a clean and dry protected area (preferably in the manufacturers case) and keep calibration certificate where you can access it for your reference.
