Our take on the FLEX FX1431-Z 1/2" Compact Impact Wrench (Tool Only)

The FLEX FX1431-Z is a 24V cordless 1/2-inch impact wrench built for tight spaces. It delivers 300 ft-lbs of fastening torque and 450 ft-lbs of nut-busting torque, and it is about 38 percent lighter than FLEX's larger FX1451. Bolt Auto Stop and Bolt Removal modes protect fasteners during tightening and stop the tool once a bolt breaks loose, and a 360-degree LED has five brightness settings. It suits automotive work and framing where a full-size wrench will not fit. Against full-size 1/2-inch impact wrenches it gives up peak torque, so heavy truck and rusted-bolt work still favors the bigger tool. It is sold as a bare tool, so you need a FLEX 24V battery and charger.

About the FLEX FX1431-Z 1/2" Compact Impact Wrench (Tool Only)

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.

Questions and answers

Does the FX1431-Z come with a battery?
No. It is a bare tool, so you need a FLEX 24V battery and charger. If you already own FLEX 24V tools, you can use those packs.
How does it compare with the FLEX FX1451?
The FX1431-Z is the compact model and is about 38 percent lighter than the FX1451. It trades some peak torque for size and weight, so it reaches tighter spots but is not the choice for the heaviest bolts.
What is Bolt Auto Stop Mode?
It stops the tool from over-tightening, breaking or stripping a bolt while you tighten. Bolt Removal Mode stops the tool once it senses the bolt has loosened.
Can it remove lug nuts?
It has 450 ft-lbs of nut-busting torque, which covers most passenger-car lug nuts. Very tight or rusted fasteners on trucks may still need a larger wrench.
How do I get the Limited Lifetime Warranty?
Register the tool at registermyFLEX.com within 30 days of purchase. The coverage applies to tools registered through December 31, 2024.
What is included in the box?
The wrench itself as a tool only. No battery, charger or case is included.
Where is the FLEX FX1431-Z 1/2" Compact Impact Wrench (Tool Only) cheapest?
