Is the FLEX Compact Impact Wrench powerful enough for lug nuts?

Yes for most passenger cars. Its 450 ft-lbs of nut-busting torque and 300 ft-lbs of fastening torque handle typical lug nuts, but heavily torqued truck or rusted fasteners may need a high-torque wrench.

Does it come with a battery?

No. It is sold as a bare tool, so you need a FLEX 24V battery and charger, or a kit that includes them.

How does it compare with full-size impact wrenches?

It is lighter and more compact but lower in torque. Full-size 1/2-inch wrenches often exceed 700 ft-lbs, while this one targets control and reach in tight spaces.

What drive size and socket type does it use?

It has a 1/2-inch square drive with a friction ring, so standard 1/2-inch impact sockets fit.

How long does the battery take to charge?

About 35 minutes with the 160W fast charger for a 3.5 Ah pack.

Is it good for engine bay work?

Yes. Its 2.6 lb weight and compact body help in tight spaces, though deep fasteners may still need an extension.

Our take on the FLEX Compact Impact Wrench

The FLEX Compact Impact Wrench is a 24V brushless 1/2-inch square-drive impact wrench rated at 450 ft-lbs of nut-busting torque and 300 ft-lbs of fastening torque. It weighs 2.6 lb and has a three-speed selector with a variable-speed trigger, plus a friction ring for quick socket changes. Its THERMA-TECH heat management is claimed to add 25% runtime, and the fast charger fills a 3.5 Ah pack in about 35 minutes. It suits mechanics and serious DIYers who want a light, compact tool for lug nuts and suspension work, though it competes with higher-torque 18V and 20V flagships and ships without a battery.
