Digital torque wrenches are a commonly found production tool across various industries. It offers torquing precision that no analog counterparts could match.

Due to their popularity, there are numerous digital torque wrench brands that you can choose from. Each offers a wide array of digital torque wrench products with varying sizes, torque ranges, accuracy levels, and prices.

For those who are new, the immense range of digital torque wrench choices in the market can be overwhelming. Fortunately, this article will walk you through the most reliable brands, compare the strengths and weaknesses of their products, and help you determine the one that suits your needs the best.

After all, you deserve the best digital torque wrench that you can get. Precision in torquing is crucial, it directly impacts the quality and safety of your products.

Important Factors in Choosing the Best Digital Torque Wrench

In a nutshell, there’s no such thing as a “perfect digital torque wrench” in the market. Each product comes with its own set of advantages and disadvantages.

Similarly, there’s no “best digital torque wrench brand”, as each brand typically aims for a certain segment of customers. Some brands can offer a more general assortment of digital torque wrenches, while others can be more oriented toward a certain niche.

Nonetheless, there are several key indicators that you should consider when buying a new digital torque wrench:

Size and Torque Range

Before buying a digital torque wrench, determining the correct wrench size and torque range is a must. Wrenches come in different sizes and torque ranges, as they are built for different purposes.

There’s a wide variety of wrench sizes, each corresponding to the nuts and bolt sizes that they can handle and their torque range. A torque range is the amount of torque (generally stated in Newton meters/Nm or foot-ponds/ft-lb) that a wrench can provide.

The most common digital torque wrench sizes are ¼, ⅜, ½, and ¾ inch wrenches. The smallest wrenches can be used to fix your gardening equipment, while the larger ones are used to fasten bolts in an airplane’s wings.

Hence, it’s important to know the type of work that your digital torque wrench will do before purchasing one.

Precision Rate

Another key indicator to look for is precision rate. A Digital torque wrench is indeed far more accurate than analog wrenches. However, they are still susceptible to imprecision.

A digital torque wrench’s precision rate is measured by its possible deviation, the difference between the torque stated on the wrench’s readings, and the actual amount of torque in the field. As a reference, the ISO 6789:2017 standards require a maximum deviation rate of ±4% or ±6% (depending on the wrench type).

Higher-end wrenches typically have a deviation rate of 2% or lower. The lower the possible deviation is, the better.

Moreover, always check if there’s a calibration certificate from the manufacturer included in the packaging. This certificate ensures that the said wrench has been proven to be accurate and ready for use. It’s also a plus point if it has passed relevant certifications, such as those from ISO or any relevant national certification body.

Wrench Material and Build Quality

While the first two factors were quantifiable, this factor is rather qualitative. Digital torque wrenches on the market are built from differing materials and varying build quality,which generally corresponds with their price.

Ideally, the wrench body should be made of a strong and corrosion-free material, such as stainless steel or chrome-plated. For the handle, choose the material that offers a firm grip and is comfortable for hand use. For this factor, it’s best to try your prospective wrenches directly and feel them for yourselves.

To add, always visually inspect the wrench for any possible defect. If any defect is spotted, immediately report it to the distributor/manufacturer. The earlier it’s detected – the better, as often your wrench has a limited guarantee period.

User-Friendliness

A decisive advantage of digital torque wrenches over their analog counterparts is the availability of a fully digital interface. Thus, it’s easier to input torque value, check the wrench’s torque readings, and integrate with quality control mechanisms.

Moreover, digital torque wrenches can also omit light (such as color-specific lamps) and/or sound (such as a beep) feedback signals to their user. These signals are useful to inform the user if the desired torque value has been reached in order to prevent overtorquing.

Furthermore, it can also notify the user if an incorrect torque value has been inputted – perfect for quality control.

Ideally, a good digital torque wrench offers both light and sound feedback signals, which allows full situational awareness to its user.

The Brand’s Existing Distribution Network

Just like any industrial machinery, a digital torque wrench can break down and require repairs from a qualified technician. Thus, the availability of spare parts and servicing agents spread in your region is a considerable factor.

The larger the brand of your digital torque wrench is, the easier it is to find spare parts and repair services. It’s in your best interest to keep downtime as minimal as possible.

Cost

Last but not least, a digital torque wrench’s cost cannot be overlooked. A digital torque wrench typically costs hundreds of Euros, with some costing beyond EUR 1,000.

Generally, its price tag corresponds as well with its features, torque range, and quality. It’s important to find a balance between the required functionality and your company’s budget.

Choosing the Right Brand for Your Needs

Choosing the most reliable digital torque wrench is indeed challenging. From the comparison above, one can generalize the types of digital torque wrenches into three 3 categories; lower-, mid-, and higher-end tiers. Each has its capabilities, features, and costs. Some wrenches can transcend this grouping and are difficult to classify due to their extraordinary features, such as Milwaukee Tool’s M12 Fuel.

In general, lower-tier wrenches are suitable for personal uses, such as building living room furniture or fixing your bicycle. They’re cheap, but not all can pass the stringent industrial requirements for precision, such as the ones set in ISO 6789:2017.

Meanwhile, mid-tier wrenches easily cost more than twice their lower-end counterparts. However, they do offer accuracy rates that are ISO 6789:2017 compliant – making them sufficient for industrial uses. They also come with color-coded lights and vibration signals, making it easier to know if the correct torque value has been applied.

Higher-end wrenches take it a step further – with an even higher precision rate and datalink capabilities than your other devices. This allows your digital torque wrench to go beyond merely tightening nuts and bolts.

It can serve purposes such as feeding real-time information for quality control purposes or a digital recorder that will be used in your future audits.

Conclusion

In conclusion, it’s best to fully understand your company’s needs before buying a digital torque wrench. These wrenches come with various features and price tags. For maximum production efficiency, it is always recommended to stick with higher-tier wrenches.

Not only do they have the best precision, but they also have one key advantage that others don’t: datalink capability. When your digital torque wrench can automatically obtain and send information with your other devices, it will save your company a good deal of cost & time.

Gone are the days when your quality control officers must go back and forth between the assembly line and the office to collect information and input them in a spreadsheet on a PC. Or the time when your company has to print hundreds of pages of instruction manuals for your workers for each industrial machinery.
