Click, Dial, or Digital? The Ultimate Guide to Torque Wrenches and When to Use Them

Whether you're a seasoned mechanic, aerospace technician, or weekend DIYer, using the right torque wrench can mean the difference between a job well done and a major mechanical failure. In this guide, we explain the differences between click, dial, and digital torque wrenches, what they’re best used for, and answer common questions we hear from our customers across Canada.

What Are the Different Types of Torque Wrenches?

1. Click Torque Wrench

The click-type torque wrench is the most common torque wrench used by mechanics and technicians. It uses a spring-loaded mechanism that disengages when the set torque is reached, producing a distinct “click” sound and feel to signal the user to stop applying force. This torque wrench is great for automotive, machinery, and general mechanical work.

How it works:

• You manually set the desired torque level (usually in foot-pounds or Newton-meters) using a calibrated handle.

• As you apply force, internal tension builds.

• When the set torque is reached, the clutch mechanism slips slightly, producing the "click."

Pros:
✅ Durable and rugged for daily use
✅ Inexpensive compared to digital options
✅ Simple, mechanical operation (no batteries)
✅ Available in many drive sizes and torque ranges

Cons:
⚠️ If you miss the “click,” you can over-torque fasteners
⚠️ Accuracy depends on regular calibration
⚠️ Not ideal for applications requiring detailed torque data logging

2. Dial Torque Wrench

Dial torque wrenches display torque values using a deflecting pointer that moves across a dial face as force is applied. Unlike the click wrench, this type does not release or alert you when the set torque is reached—you must watch the dial and stop at the right point. This torque wrench is great for aerospace and lab settings.

How it works:

• The applied torque causes the main shaft to flex, and this motion moves a needle across a dial indicator.

• You visually track the torque in real time.

Pros:
✅ Highly accurate and consistent
✅ Easy to monitor real-time torque application
✅ Ideal for slow, controlled torqueing
✅ Great for non-destructive torque testing

Cons:
⚠️ Requires constant visual attention
⚠️ Bulky and less ergonomic in tight spaces
⚠️ Usually more expensive than click wrenches
⚠️ Slower workflow in high-volume environments

3. Digital (Electronic) Torque Wrench

Digital or electronic torque wrenches use strain gauge technology to electronically measure applied torque and display the value on a screen. Many models provide alerts (beeps, vibrations, flashing lights) to notify you when you're approaching or reaching your target torque. This torque wrench is used in precision manufacturing, tech assembly lines and any job requiring data capture or logging.

How it works:

• You set the desired torque via buttons or a touchscreen.

• As you apply force, an internal sensor measures torque and relays it to a display.

• Alerts notify the user as they near the torque threshold.

Pros:
✅ Extremely accurate (±1% or better)
✅ Often includes data logging, angle measurement, and USB/Bluetooth connectivity
✅ Ideal for documentation and compliance in regulated industries
✅ User-friendly alerts reduce human error

Cons:
⚠️ Battery powered — requires charging or replacement
⚠️ More delicate electronics — not ideal for heavy-duty abuse
⚠️ Higher initial cost
⚠️ Can be overkill for basic jobs

FAQs

What is the best torque wrench for automotive repair in Canada?

The click-type torque wrench is the most reliable and affordable option for automotive use. It provides consistent results and is widely used by mechanics in Calgary and Ontario.

Where can I get my torque wrench calibrated in Calgary?

You can get professional torque wrench calibration at Torque Medic. We service tools from all major brands and issue calibration certificates for compliance.

How often should I calibrate my torque wrench?

We recommend calibration every 12 months, or every 5,000 cycles—whichever comes first. This ensures accuracy and prevents costly mistakes.

Do digital torque wrenches need calibration?

Yes. Digital torque wrenches are highly accurate, but they still require regular calibration and battery maintenance, especially in regulated environments.
