You know you need to buy an electric torque wrench, but the number of options can be overwhelming. If you’re unsure which one to buy, this handy guide will help steer you in the right direction. We’ve compiled a list of our favourite electric torque wrenches and pulled out their best features to make your decision as easy as possible!
Torque Accuracy
Torque is the strength of a bolt or screw which is applied as a twisting force. If you want to tighten bolts or screws to the exact amount, then you need an accurate torque wrench. This can be achieved through various means including internal calibration, external calibration and even using an actual torque wrench with a dial indicator. You can also test your torque right in your workshop to ensure accuracy.
Magnetic vs. Electronic
If you’ve shopped for a torque wrench in the past, you may have noticed two different styles in use. The first is the mechanical style, which uses a spring-loaded internal mechanism to apply torque. The second style is what’s known as electronic or digital, which uses an electronic circuit to apply torque. Electronic wrenches are a good choice if you need more accuracy or want to avoid backlash when applying torque.
Torque Range
The torque range is the highest and lowest amount of torque a wrench can apply. The wider the range, the more options you’ll have to work with. You may want to avoid wrenches with longer ranges if you need something more specific that only goes up to a certain amount. For example, if your car axle needs to be torqued at 65 ft-lbs and your wrench goes up to 250 ft-lbs, then it won’t be able to get the job done for you.
Handle and Grip
Grips can make a big difference in comfort and usability. The handle should match your hand comfortably and provide a good grip to avoid slippage. When you’re using a wrench for hours at a time, the last thing you want is something that makes your hand cramp up! Avoid ones with flimsy plastic handles, especially if they come apart easily or have sharp edges that dig into your hand.
Torque Adjustability
You may need to adjust the amount of torque based on the object you’re working with. If a bolt is stuck in something, you may need to apply more torque than usual to get it out. A wrench that can be adjusted in small increments (the smaller the better) will give you more control over how much torque gets applied to a bolt or screw. You never want too much or too little.
Length
When you shop for a torque wrench, you may want to consider the length. If you’re working on a shorter part, you’ll need a shorter wrench to avoid over-torquing. On the other hand, if it’s longer, you’ll need a longer wrench. You never want too short or too long! A good rule of thumb would be measuring the longest side of your wrench and adding two inches for extra length.
Space Saving
If you want to keep a wrench within easy reach, consider the space it takes up in your tool kit. You may need multiple wrenches of different sizes or sizes that will fit your specific needs. A good torque wrench should fit every bit of space you have without taking up too much room!
Conclusion
The right torque wrench is out there, you just need to find it. Find one that meets your needs and works well with your hands and the work you’re putting it through. By considering these tips, you’ll be able to choose the best wrench for your workshop!
