The Flex FX1431-Z is a compact 24V brushless 1/2-inch impact wrench with a friction-ring square drive. It delivers 450 ft-lbs of nut-busting torque and 300 ft-lbs of fastening torque from a body that weighs about 2.6 lb, roughly 38 percent lighter than Flex's larger FX1451. Three speed settings, Bolt Auto Stop, Bolt Removal Mode and a five-level 360-degree LED set it apart from simpler one-speed compact wrenches. It suits auto mechanics and framers who want a light tool for lug nuts, suspension bolts and structural screws, but it ships as a bare tool, so you need Flex 24V batteries and a charger.

Owners rate it very highly, praising the power-to-weight ratio, the smooth trigger and the bolt modes. Most complaints center on it being a bare tool and on the cost of entering the Flex battery platform.
The FLEX 24V 1/2” Compact Impact Wrench packs big power into a compact size so you can power through the day with a lightweight, durable tool built to conquer hard-to-reach spaces. This compact cordless impact wrench is 38 percent lighter than its larger counterpart, FX1451, and an ideal tool for automotive and framing applications. This powerful 1/2-inch impact wrench delivers 300 foot-pounds of fastening torque and 450 foot-pounds of nut-busting torque for demanding jobs. When tightening or loosening bolts and lug nuts, Bolt Auto Stop Mode prevents over-tightening, breaking, or stripping the bolt while Bolt Removal Mode stops the tool when it senses the bolt is loosened. Screw Mode delivers faster speed for wood-driving applications like driving SDS screws into pine or LVL. Its 360-degree LED lights up dark areas with five adjustable brightness settings. The ergonomic design and soft-grip handle paired with a variable speed trigger deliver ideal balance, comfort, and total control. This compact impact wrench delivers the FLEX Advantage of unmatched battery power, runtime, and fast charging (battery and charger sold separately)
