Best Impact Wrenches (2026 Buying Guide)
Part of our Complete Power Tools Hub inside the Home & Infrastructure Hub.
Impact wrenches are built for high-torque fastening tasks such as removing lug nuts, assembling structural bolts, and handling automotive repairs. Unlike impact drivers, impact wrenches deliver significantly more torque and are designed for heavy-duty applications.
If you're comparing lighter fastening tools first, review our Impact Driver Guide and Drill & Impact Combo Kits Guide.

| Light Duty | 150–250 ft-lbs | Small bolts & maintenance | 3/8 inch |
| Mid-Range | 300–600 ft-lbs | Lug nuts & automotive repairs | 1/2 inch |
| High Output | 600+ ft-lbs | Heavy-duty mechanical work | 1/2–3/4 inch |
Corded, Cordless, or Pneumatic?
Cordless Impact Wrenches
Modern 18V and 20V cordless impact wrenches deliver strong torque without air hoses or compressors. Ideal for tire changes, suspension work, and home garage applications.
Pneumatic Impact Wrenches
Air-powered models are lighter and commonly used in professional garages. They require a compatible air compressor with adequate CFM output. See our Air Compressor Guide.
Corded Models
Less common today, but they provide consistent power when outlet access is reliable and mobility is less important.
Impact Driver vs Impact Wrench
Impact drivers and impact wrenches both deliver high torque, but they serve different purposes. Impact drivers use hex bits for driving screws and structural fasteners, while impact wrenches use square drives designed for sockets and heavy bolts.
For screw driving and construction fasteners, see our Impact Driver Guide.
