What is an Impact Wrench?

Impact wrenches do a great job of tightening and loosening bolts, lug nuts and rusted fasteners. They provide a very high rotational torque that regular drills are simply not capable of and deliver high torque output with minimal exertion by the user.

They are typically used in the automotive and construction industry, though are loved across many other trades where a high torque output is needed. Torque is the amount of force required to make something move.

Fact - Did you know that impact wrenches are used in Grand Prix races to change wheels during pit stops? 

How Does an Impact Wrench Work?

The impact wrench replaces your ratchet wrench or breaker bar, highly increasing your productivity and making tightening and loosening nuts and bolts a much quicker and easier process. They get their immense torque from a hammering mechanism in the motor that delivers extremely strong and quick concussive blows. This creates a huge amount of force which enables them to loosen even the toughest nuts and bolts.

The motor applies a continuous sudden twisting motion to the nut or bolt, usually in short bursts, and this will eventually bring movement (loosening or tightening) to the bolt.

They are used in applications where a much greater force is required such as when the nut may not break loose, or a hand wrench wont do the job. The most common use for impact wrenches is to change car tyres. They are most commonly air powered or battery powered, both of which you can shop at Altiven.co.za

When used properly, there is no lug nut - no matter how tight - that an impact wrench can't budge.

Impact wrenches are available in every standard socket drive size. 3/4" and 1" drives offer you the most power for industrial scale jobs, though 1/2" is usually the most common. Impact wrenches are very powerful tools. They pack a punch and the force they use is measured in ft.lbs (foot-pounds).

The higher the torque specification on your model, the more force it can apply to the fastener.

They aren't typically used for standard home renovations and DIY, but more for professional trade use. Use them with impact sockets that suit the drive of your tool.

Tip: Dont rely solely on you impact wrench. For torque sensitive fasteners such as wheel nuts, you should opt for your torque wrench to apply the final tension to these jobs. 

Air impact wrenches are more suited to workshop use as it's unlikely you will have access to an air compressor on the move. Battery powered models these days are just as powerful.

What's the Difference Between an Impact Driver and an Impact Wrench?

Impact wrenches are not to be confused with impact drivers.

The impact wrench is a fastening tool which uses a square drive that you can attach sockets to in order to tighten and loosen bolts. The impact driver is a screwdriving specialist that has a 1/4" hex collet that accepts 1/4" hex shank bits. It is typically used to drive long screws and bolts. They are much more efficient at driving screws than standard drill drivers.

For any high torque situation, you should opt for an impact wrench.

Things to Look for When Choosing an Impact Wrench

We have listed below some main features to look out for when choosing an impact wrench. Of course, the features you go for depends on the applications you will be carrying out.

• Look out for features such as 'high torque'. The higher the torque (measured in newton metres (Nm)) the more twisting force the machine can produce
• Brushless motors offer a longer runtime and better performance
• Impact wrenches with a hog ring socket provide more efficient torque delivery
• Models with multiple torque settings allow you to tailer the torque output to the application.
