The Buyer’s Guide
Accuracy is the most essential feature to check when buying any torque wrench and the adapters are not an exception. You will just waste effort and time in vain if you buy a cheap and improperly calibrated tool. Besides inaccurate tools can become a reason for serious vehicle malfunction. To avoid any false reading, invest in the adapters that come with a calibration certificate.
The most accurate tools allow no more than 0.5% error in both directions. But the error up to +/- 4% is totally acceptable. Digital torque wrenches and adapters are typically more accurate than analog tools.
Digital LCD screens provide better readability options than analog tools because the manual instruments are not always good to read at night or poorly lit rooms. The digital screens of adapters should have a wide view angle so you could read the markings in any position. Also, the display of a digital torque adapter has to be bright, with a backlit, clearly readable and offer the font settings.
One of the best reasons to buy a digital adapter for measuring torque range is a set of versatile functions. Advanced adapters offer a few extra settings:
- LED lights for additional notification after reaching the torque limit;
- The audio alert system with beep or click sounds for the same reason;
- Different peak and trace modes;
- Different measurement settings to read the marking and increments in metric and Imperial systems;
Surely, you should skip the instruments made of cheap materials. Yes, the price may be attractive but such a tool won’t last long. So, consider avoiding any instruments with plastic details, especially if the body is made of plastic. It is quite possible to save a few dollars even on top-notch adapters made of metal.
Besides, all high-end digital torque adapters are designed to withstand strong applied forces. It should survive through drops and slippage. All-steel and metal adapters can last much longer than any plastic tool.
Battery and power
A digital torque adapter should not sit idle on your garage shelf. You should use this instrument frequently. And sometimes you may need to use this instrument right in the middle of the road. In all these cases, it is better to use adapters with strong and long-lasting batteries that require occasional charging. Check the user reviews for the actual battery life of particular instruments.
Some adapters have an energy-saving feature of automatic shutdown if they remain inactive. For example, if you forgot to turn the adapter off after using it.
Digital adapters are supposed to be lightweight so you could carry them in a back pocket. However, the small and lightweight adapters may have a non-ergonomic design that a user may find inconvenient. Typically, the weight of adapters varies from 5 ounces to 2 pounds. It is better to stick to the mid-weight up to 1 pound.
Torque range and size
The larger size, the more flexible tool is. Consider spending a few extra bucks to buy a long and versatile adapter that already comes with different socket heads. As you might have noticed, the most common adapter’s drive size is 1/2-inches. Such adapters are more affordable and widely used for the majority of nuts, bolts and screws. However, if the adapter offers the options of 3/8 and 1/4-inch ratchets for a reasonable price.
The same approach is relevant to the tool’s torque range. The larger this range, the more accurate results the adapter can deliver.
