Automotive Impact Wrench

An automotive impact wrench is the fastest way to break loose stubborn lug nuts, suspension bolts, and rusted fasteners without killing your arms.

At ArcCaptain, we bring shop‑ready impact wrenches built for people who already care about torque, metal, and real work. This collection is made for garage builds, fabrication projects, and repair jobs where speed, control, and muscle matter.

Whether you’re swapping wheels, working on frames, or tearing down parts before welding, our automotive impact wrenches deliver high torque output, smooth trigger control, and cordless freedom.

Built to Break Bolts, Not Your Rhythm

These automotive impact wrenches are designed for real automotive work, not light-duty fixes. They hit hard when needed and stay controlled when precision matters.

High Torque That Actually Moves Stuck Fasteners

Modern motors and impact mechanisms deliver strong breakaway torque for lug nuts, axle nuts, and suspension hardware. You spend less time fighting rust and more time building.

Brushless Efficiency for Longer Jobs

Brushless designs run cooler and waste less power. That means longer runtime and consistent force from the first bolt to the last.

• Strong torque for wheels, frames, and brackets
• Consistent power under load
• Less strain on hands and wrists

Cordless Freedom That Fits the Garage and the Job Site

Dragging air hoses or cords slows everything down. Cordless automotive impact wrenches keep your workflow clean and mobile.

Compact Size for Tight Engine Bays

Slim profiles and balanced weight help you reach brake assemblies, undercarriage bolts, and tight clearances with ease.

Fast Battery Swaps, No Downtime

Quick battery changes keep you moving during tire rotations or teardown work. No waiting for pressure to build or cords to untangle.

• Easy to move around vehicles
• Works indoors or outdoors
• Cleaner setup around welding tables

Control That Protects Threads and Parts

Raw power is useless without control. These impact wrenches give you the feel you need for automotive work. Smooth trigger response lets you seat fasteners gently before applying full torque. This helps prevent cross-threading and damage.

Multiple Torque Settings for Mixed Tasks

Lower settings handle smaller bolts. Higher settings handle lug nuts and structural fasteners. One tool covers many jobs.

• Better control on reassembly
• Reduced risk of snapped bolts
• Cleaner, safer automotive work

Made for Builders, Welders, and Metal Workers

If you weld, fabricate, or restore, an automotive impact wrench is part of the system. Tear-down is faster. Prep work is cleaner. Projects move forward. Impact-resistant bodies handle drops, dust, and daily use. These tools are meant to live next to grinders and welders.

Perfect Pairing With Fabrication Workflows

Remove parts fast, weld clean, reinstall with confidence. It all flows better when disassembly is easy.

• Ideal for fabrication prep
• Saves time before welding
• Built for real shop conditions

FAQs on Automotive Impact Wrench

How much torque do I need in an impact wrench for automotive work?

Most automotive work needs between 250 and 500 ft-lbs of torque. Lug nuts, suspension bolts, and brake components usually fall in this range. Higher torque is helpful for rusted or seized fasteners, but control is just as important as raw power.

What is the 20 100 rule for torque wrenches?

The 20 to 100 rule means a torque wrench is most accurate between 20 percent and 100 percent of its rated capacity. Using it below that range can reduce accuracy. This is why choosing the right torque range for automotive fasteners matters.

What should you not do with an impact wrench?

Do not use an impact wrench for final torque tightening. Impacts can easily over-tighten fasteners and stretch bolts. Always finish critical automotive fasteners with a proper torque wrench.

What size impact wrench is best for cars?

A 1/2-inch drive impact wrench is the best all-around size for automotive work. It handles lug nuts, suspension bolts, and most chassis fasteners. Smaller 3/8-inch tools work for light tasks, but lack power for wheels.

Can an impact wrench damage car parts?

Yes, if used incorrectly. Too much torque or poor control can strip threads or snap bolts. Using proper settings and stopping before final tightening helps protect parts and ensures safe reassembly.
