The FLEX FX1431-Z is a 24V cordless compact impact wrench with a 1/2-inch anvil. It is 38 percent lighter than the larger FX1451 and suits tight spaces, including automotive and framing work. It delivers 300 ft-lbs of fastening torque and 450 ft-lbs of nut-busting torque.
Bolt Auto Stop Mode helps prevent over-tightening, breaking or stripping a bolt. Bolt Removal Mode stops the tool when it senses the bolt has loosened. Screw Mode runs at a faster speed for driving wood screws, such as SDS screws into pine or LVL.
A 360-degree LED lights dark work areas and has five adjustable brightness settings. The soft-grip handle and variable speed trigger give control and balance. The tool runs on FLEX 24V Stacked Lithium batteries and works with all FLEX 24V batteries, chargers and tools. This version is sold as a tool only.
