Overview
This is a 3/8 inch drive impact tool weighing 2.2 pounds, sized for bolts and fasteners that call for a 3/8 inch square drive rather than the larger 1/2 inch size common on heavier impact wrenches.
The 3/8 inch drive size makes this a mid-size option, smaller and typically easier to maneuver in tight spaces than a 1/2 inch impact wrench, but with less torque ceiling for large fasteners. Power source is not listed in the available specs, so confirm whether this is corded, cordless or pneumatic before buying.
- 3/8 inch square drive
- 2.2 pound weight
- Impact-style tool
- Sized for smaller fasteners
Who it's for
Suited to users working on smaller fasteners in tight spaces, such as automotive or light mechanical work, where a 3/8 inch drive covers the bolt sizes involved. Not the right pick for heavy-duty jobs like lug nuts or large equipment fasteners that typically call for 1/2 inch drive or larger.
Strengths and trade-offs
Drawn from this product's published specifications.
- Compact 3/8 inch drive size
- Light at 2.2 pounds
- Power source not specified in listing
- Lower torque ceiling than 1/2 inch drive tools
Performance notes
Drive size is the main limiter here: a 3/8 inch square drive generally caps torque output below what 1/2 inch impact wrenches deliver, which is why it suits smaller fasteners rather than heavy-duty removal work. At 2.2 pounds, the tool is light enough for one-handed use in cramped spaces.
