For the casual mechanic, this is probably more than enough power to get you through most common tightening and loosening applications. And it achieves all that performance and portability in a 3.3-pound. framework.

The Hart HPIW01 uses a friction ring for quick socket changes. An integrated LED work light lets you see what you’re doing, even when you’re under your hood or in a place where the light isn’t optimal.

Our thoughts

This 350 foot-pound number appears to fall under Torque Loosen. Still, even a few hundred foot-pounds of fastening torque will do most jobs you’ll find in the amateur or hobbyist automotive world. A tool like this can remove most lug nuts from cars and trucks to zero-turn lawnmowers. It also gives you the option of bailing out a lug nut until you hit the striking mechanism – and then mess with a torque wrench to get the exact amount you need.
