TIP: Tightening the nuts and bolts will produce the required torque. It is imperative that you check the maximum torque of the impact wrench because this varies by brand and it should be determined by what you are trying to tighten with the machine.

Impact driver:


Impact drivers are available in both manual as well as electric versions, but most people tend to refer to the electric versions when they mention impact drivers. Electric impact drivers are generally light and easy to use compared to manual impact drivers. Various electric impact drivers are available, including corded as well as cordless models. An ingenious tool used for losing and tightening a variety of screws, carriage bolts, nuts, and screws anchors. 

It uses the impact of the screw to insert screws directly into the wood without the use of a pilot hole, such as in sheathing and decking. This is one of the most versatile power tools that allows for one-handed operation to install and remove screws and bolts.

In order for the bits to fit the chuck, the shank of the bit must be hex 14.8 inches in length. There is a sufficient amount of power and torque within the motor to facilitate easy and accurate driving of these types of fasteners into wood, metal, or light concrete. While it is capable of boring holes using a spade-style bit, it wasn’t designed to drill holes.

Uses of Impact Driver: 

Self-tapping wood screws are the primary use of impact drivers. There has been a dramatic rise in the popularity of battery-operated tools in the woodwork industry. Additionally, impact drivers are also useful for builders and carpenters, especially when they are going to be required to hold a complex project together with multiple fasteners.

Generally, an impact driver will perform well in the following cases:

FACT: Do you know that impact wrenches are used during pit stops at Grand Prix races to change wheels?

When using an impact wrench to replace your ratchet and breaker bar, you will gain significant productivity increases, as well as deliver a high level of torque, all at the same time. There is no doubt that you can tighten and loosen nuts and bolts in a faster and easier manner by using a corded or cordless impact wrench that easily fits in any toolbox. There are two main types of impact wrenches available to customers, either electric or air-powered. An impact wrench features a motor for providing power to the tool in order to loosen tight nuts.

The use of compressed air as a torque source can be beneficial for larger construction projects. The impact wrenches, despite their small size, are extremely powerful. As a result of hammering the motor, you are able to generate huge amounts of torque and deliver concussive blows to the head that are very powerful and fast. It moves a bolt by continuously twisting the nut or bolt, usually in short bursts. Because of this, they are capable of removing even the most stubborn nuts and bolts.


By using an impact wrench, especially by automotive mechanics, it is capable of loosening and fastening nuts and bolts quickly and effectively.

  • In cases where a hand wrench cannot loosen a nut, these tools are useful.
  • The most common use of impact wrenches is changing car tires.
  • Besides auto workshops, they’re also used in construction.

TIP: An air regulator controls the torque of an air impact wrench. Air regulators can either be connected to the end pressure line or to the impact wrench. To adjust the output torque, adjust the air regulator.

Differences Between Impact Drivers and Impact Wrenches

Impact wrenches have a 12-inch square drive, which helps them to fit into tight spaces. DIY enthusiasts tend to prefer impact drivers because they can drive bolts and nuts as well as come with hex collet sizes ranging from 7-inch to 14-inch. You can use an impact driver to drive screws into metal or wood, in addition to tightening or loosening nuts. 

Since impact wrenches are heavier and have a high force than impact drivers, Eventually they become difficult to carry and operate by hand for a long time. Moreover, impact drivers are significantly lighter than impact wrenches and thus are more convenient to manage. Thus, they are easier to hold and use.
