Impact Wrenches

Learn more about impact wrenches

Selecting the right impact wrench is critical for achieving high joint tension and removing seized fixings quickly. Unlike standard impact drivers that use 1/4-inch hex chucks for screws, impact wrenches utilise square drive anvils with friction rings or pin detents to secure high-torque impact sockets. Advanced multi-stage electronic speed controls allow you to adjust torque delivery precisely, preventing thread stripping or over-tightening delicate mechanical assemblies.

Typical uses

• Wheel nut and lug nut work on vehicles and plant equipment.

• Repeated fastening where extra breakaway torque is needed.

• Workshop and site tasks where a compact impact wrench helps in tighter spaces.

• General trade fastening where the drive size needs to match the socket set.

How to choose the right impact wrench

• Choose the drive size first.

• A 1/2 impact wrench is usually the starting point for heavier fastening and larger sockets.

• A 3/8 impact wrench suits lighter work and tighter access.

• A 1/4 impact wrench is better for smaller fixings and accessories.

• Then pick the power source that fits the job.

• A cordless impact wrench gives you movement around site.

• A mains powered impact wrench suits fixed workshop use.

• An air impact wrench works with a compressor for bench-based tasks.

• If you’re working in confined areas, a compact impact wrench can make access easier.

• If you need longer runtime and durability from a cordless setup, a brushless impact wrench is worth comparing.

Before you order

• Match the drive size to the fixing and socket size.

• Check the product specifications for torque, impact rate, power source and included accessories.

• Use impact rated sockets and accessories where the tool requires them.

• Confirm the application suits the tool, especially for wheel work, repeated assembly or heavier site use.

• Use the category filters to narrow by drive size, power source and output.
