Must Have Features of The Best Digital Torque Adapter
Want to spend your hard-earned money on the best digital torque adapter to add to your toolbag?
Then it would be best if you looked for one that meets all of the criteria listed below.
Drive Size
To ensure that you can use a digital torque adapter and transform your standard wrench into a powerful torque wrench, you must first ensure that its drive will fit the adapter.
If you have a 1/2′′ wrench, you’ll need a 1/2′′ digital torque adapter. The same goes with a 3/8″ wrench.
The good news is that some of these digital torque adapters include drive adapters of various sizes, allowing users to utilize their 1/2′′, 3/8′′, and 3/4′′ wrenches.
Torque Range
Another important feature of a digital torque adapter is choosing one with a torque range that meets your requirements.
To do so, I recommend making a list of the tasks you perform with a torque wrench and noting the torque values they require. Then, once you’ve written down all of the measurements, double-check that they’re included in the torque range of the digital torque adapter you’re about to acquire.
If you ask me, a digital torque adapter with a torque range of 20 to 200 ft/lbs is more than adequate for an ordinary mechanic or tradesman.
Conveniente Modes
The modes of digital torque adapters are another major issue.
These torque modes can make your life easier if you use them correctly. So, here are the modes that I consider “necessary” for a digital torque adapter:
- Trace mode: When in use, this mode allows the user to watch the torque level that the wrench is generating.
- Peak mode: When a high torque level is reached, this mode alerts the user. This is normally accomplished through the use of both visual and audible cues, and it is critical when working on equipment that require precise torque when fastening nuts and bolts.
- Calibration mode: This is an excellent mode for calibrating torque wrenches that I believe is essential in all digital torque adaptes
High Accuracy
When you purchase a digital torque adapter, you are purchasing a tool that is designed to increase the power and convenience of a standard wrench.
As a result, most of these adapters have a torque range that the manufacturer specifies. However, in most cases, these torque ranges aren’t very accurate, which might cause significant disruptions in your workflow if torque accuracy is required when tightening nuts and bolts.
As a result, I believe that the best digital torque adapter should have no more than +/- 2% accuracy.
Easy-to-Read Rotatable LCD Screen
One significant difficulty with digital torque adapters for mechanics is that the LCD screen that displays the torque levels is difficult to see, which negates the point of buying such a device.
This is why, in my opinion, the ideal digital torque adapter should have a large LCD screen with large, easy-to-read numbers. The screen should also rotate so that the user can read the torque levels from any position.
Oh, and backlit screens have a significant advantage in that they let the user to read the screen in low-light situations, which are very common for mechanics.
Alert Type
This is a feature that is sometimes neglected in digital torque adapters.
A digital torque adapter usually provides visual and audible feedback to the user when a preset torque is reached. Unfortunately, these notifications are extremely difficult to hear, rendering them utterly useless.
That’s why I feel the best digital torque adapter should have a loud enough alert type for any mechanic to hear.
Frequently Asked Questions
You now know what my top picks for the best digital torque adapter are.
However, you might still have a few unanswered questions, which is why I made the following section that answers the most frequent ones.
What’s the best digital torque adapter good for?
A digital torque adapter is ideal for “expanding” the functionality of your standard wrench.
Its benefit is based on the three most common modes that this adapter provides:
- Trace mode: Allows the user to monitor the amount of torque applied by the adapter, which is ideal for avoiding breaking nuts and bolts.
- Peak mode: Once the preset torque is defined in the digital torque adapter, it produces a visual and auditory signal when that torque level is reached, which is ideal for mechanics who require maximum accuracy in their torque levels.
- Calibrating mode: With this mode, the user can calibrate the torque wrench to ensure that it is always calibrated, preserving the correct torque output to maintain accuracy.
So, if you want to make your wrench significantly more powerful and accurate, a digital torque adapter may be the best option for you.
Are digital torque adapters accurate?
This is heavily dependent on the digital torque adapter model.
Fortunately, most manufacturers will inform you of the torque range accuracy of a specific digital torque adapter.
For example, the NEIKO 20743A 3/4″ digital torque adapter has a torque range of 29.5-147.5 ft./lb. with perfect accuracy.
My recommendation is to purchase a digital torque adapter with less than +/- 3 percent accuracy. A lower accuracy could cause severe problems in your workflow.
Can you put an adapter on a torque wrench?
You most definitely can.
In fact, the best digital torque adapters come with adapters to fit all wrenches. That’s how you’ll find 1/2″ digital torque adapters with 3/8″, and 3/4″ adapters.
