Buying Guide:
Now that you’ve seen some of the top contenders, here’s a guide to help you choose the perfect torque wrench for your needs:
Type of Wrench
- Click Wrench: The most common type emits a click when the desired torque is reached. (All the wrenches on our list are click wrenches.)
- Beam Wrench: Uses a bending beam to indicate torque, and requires experience to interpret readings.
- Digital Wrench: Provides a digital readout of torque value, generally more expensive.
Range:
Consider the torque requirements of the projects you’ll be tackling. Most household DIY tasks fall within a range of 10-250 ft-lbs.
Drive Size:
The drive size refers to the socket size the wrench can accommodate. Common options include 1/4-inch (for small bolts), 3/8-inch (versatile for many tasks), and ½-inch (for larger bolts and nuts).
Measurement Unit:
Most torque wrenches display ft-lbs (foot-pounds) but some may offer in-lbs (inch-pounds) or Nm (Newton meters). Ensure the wrench uses the unit system you’re comfortable with or can easily convert between.
Head Type:
Some wrenches have a fixed head, while others have a reversible head for both tightening and loosening. Choose based on your anticipated needs.
How to Use Torque Wrenches:
- Set a Range: Using the adjustment mechanism, set the desired torque value on the wrench’s scale.
- Attach the Socket: Select the appropriate socket size for the bolt or nut you’re working on and attach it to the wrench’s drive end.
- Attach the Bolt: Position the socket over the bolt or nut and ensure a secure fit.
- Fasten the Nut: Slowly and steadily apply pressure to the wrench handle until you hear the click (or reach the indicated value on a digital wrench). This signals that the desired torque has been achieved. Important: Do not apply further force after the click.
Types of Torque Wrenches
- Click Wrench (Most Common): As mentioned earlier, click wrenches are the most popular type for DIY use. They offer a user-friendly experience with an audible and tactile click that indicates when the desired torque is reached. They typically have a micrometer-like adjustment mechanism for setting the torque value.
- Beam Wrench: Beam wrenches are a more traditional design that utilizes a bending beam to display torque. A deflection on the beam corresponds to a specific torque value on a scale. These wrenches require some practice to interpret readings accurately and may not be as precise as click wrenches.
- Split-beam Wrench: A variation of the beam wrench, the split-beam design incorporates a breakaway feature. Once the desired torque is reached, the split beam separates, preventing further tightening and protecting against over-torquing.
- Digital Torque Wrench: Digital torque wrenches offer the most advanced option. They feature a digital display that shows the real-time torque value as you tighten. This allows for the most precise control and eliminates the need to interpret click sounds or beam deflection. However, digital wrenches are generally more expensive than click or beam wrenches.

What Are the Advantages of Using Torque Wrenches?
- Prevents Over-Tightening: Over-tightening can damage threads, strip bolts, or even crack components. Torque wrenches ensure you apply the exact amount of force required for a secure and safe connection.
- Improves Accuracy: Torque wrenches remove the guesswork from tightening bolts and nuts. You can be confident that critical components are fastened to the manufacturer’s specifications.
- Ensures Consistent Results: Torque wrenches allow you to achieve consistent tightness across multiple fasteners, which is crucial for proper assembly and performance.
- Reduces Risk of Damage: By preventing over-tightening and ensuring proper torque, torque wrenches help safeguard your project from potential damage.
FAQs About Top 7 Best Torque Wrench Under $100
Can I calibrate a torque wrench myself?
It’s not recommended for most DIY users. Calibration requires specialized tools and expertise. Consult the manufacturer’s instructions for recommended calibration intervals and consider sending your wrench to a certified service center.
How often should I calibrate my torque wrench?
Calibration frequency depends on usage and the manufacturer’s recommendations. Generally, for occasional DIY use, a calibration every year or two might be sufficient. More frequent use or critical applications might warrant more frequent calibration.
What happens if I use a broken torque wrench?
A faulty torque wrench can provide inaccurate readings, potentially leading to over-tightening or under-tightening. Always ensure your torque wrench is in good working condition before use. If you suspect a problem, have it inspected by a qualified professional.
Can I use a cheater bar with a torque wrench?
Never use a cheater bar (pipe extension) with a torque wrench. This increases the leverage and can significantly alter the applied torque, potentially causing damage.
