Are There Different Types Of Torque Wrenches?
While you might think all torque wrenches are alike, they are not. Most average classic car owners who work on their car use a basic “click” type torque wrench, but many automotive applications (as well as HVAC or plumbing) require exact amounts of torque to accomplish the task. The following descriptions list several torque wrenches most commonly used in classic car restoration projects.
Click Torque Wrench
This wrench is the most basic and standard torque tool in a mechanic’s toolbox. When the preset torque level is reached, the wrench will emit a “click” or “beep.” These wrenches can be purchased in various load limits and are perfect in areas where the mechanic might need to be careful about overtighting a bolt or nut.
Beam Torque Wrench
The beam torque wrench is longer and has a flexible, pivoting handle that moves as the torque increases. The wench is shaped like a long lever (beam) and uses fundamental physics to allow users to move to an exact amount of torque. Most beam wrenches have dials on the handle that displays ft/lbs or Nm readings. They are the simplest in design and usually last a lifetime.
Split Beam Torque Wrench
The split beam is just like you imagine. It uses two beams to deliver exact torque pressure. One beam connects to the handle for torque pressure, and the second is attached to the head as an indicator beam. Most torque wrenches have dials built into the handles that allow you to preset the desired level, lock it into place, and then it will “click” or “beep” when the level is reached.
Digital Torque Wrench
Digital torque wrenches can be expensive, but it is also more accurate. The wrench registers the torque electronically inside the handle and displays the desired torque setting in an LED window. An electronic torque wrench tends to be more delicate and requires batteries.
What Are The Best Torque Wrenches?
Several companies make excellent torque wrenches for purchase in various sizes. We’ve included our favorites below.

The Craftsman Torque Wrench is another good value in a standard wrench if you need one for occasional use. It is an Amazon Choice award winner and exceeds all ASME standards. The wrench is made from steel alloy and is very durable. The locking display is built into the handle.
The torque gauge is a rotary dial situated at the top of the hand grip, and we appreciated that Craftsman made the grip hand-friendly. While a rotary dial is simple to use, we wondered if it might be prone to slipping, but every review indicates that the wrench performed admirably.
The torque wrench is made in China but doesn’t seem cheap. The only thing that could e improved on is the carrying case. (The case will wear out long before the wrench does). Craftsman offers the wrench in ½ “ or ⅜” sockets (we wish they had included an extender and an adapter with each one, but they don’t.

How Are A Torque Wrench And An Impact Wrench Different?
Torque wrenches are manually operated, while impact tools are power-generated through compressed air or electricity. Impact wrenches are commonly used to loosen lug nuts, rusted nuts, or bolts that a manual wrench cannot budge. The impact wrench can often loosen or tighten nuts faster than a standard wrench can manage. The downfall of impact wrenches is that the torque they produce cannot be controlled, which a torque wrench can do. (If you ever wondered why oil pan plugs are so challenging to remove, become stripped, or are overtightened is because somebody used a power wrench they shouldn’t have.
