Overview
WORKPRO's 4-Inch Stubby Adjustable Wrench is a compact wrench with a 0.94 inch jaw capacity, sized to reach fasteners in tight clearances where a full-length wrench will not fit.
Stubby wrenches trade handle leverage for reach, since the short body lets you position the jaws in gaps too narrow for a standard adjustable wrench. At 3.2 ounces it adds almost nothing to a pocket or pouch. The 0.94 inch jaw opening covers small to mid-size fasteners rather than large nuts or bolts.
- Length: 4 inches
- Jaw capacity: 0.94 inches
- Weight: 3.2 ounces
- Style: stubby adjustable
Who it's for
Anyone working in cramped clearances, under dashboards, behind appliances, in tight plumbing runs, benefits from a wrench this short. Those needing serious torque should look elsewhere.
Pros and cons
- Fits gaps a full-size wrench cannot
- Light at 3.2 ounces
- Adjustable jaw handles multiple sizes
- Short handle limits torque leverage
- 0.94 inch capacity caps fastener size
- Not suited to large bolts or nuts
Performance notes
The short 4 inch body limits how much leverage you can apply, so a fastener that a full-size wrench would turn with ease can take more effort here. That same short length is what lets the jaws reach into gaps a standard adjustable wrench cannot enter. The 0.94 inch jaw capacity fits small and medium fasteners, not oversized nuts or bolt heads.
