Overview
The Craftsman 45570 is a 16 inch adjustable wrench with roughly a 6.38 inch jaw opening, sized for larger nuts, pipe fittings and stuck bolts that a small wrench cannot reach around. It weighs 15.2 ounces, enough heft to add leverage without becoming unwieldy for most one-handed use.
Craftsman has built adjustable wrenches for generations, and this one sits at the larger end of that range rather than the compact 6 or 8 inch sizes most toolboxes already carry.
- 16 inch overall length
- About 6.38 inch jaw capacity
- 15.2 ounce weight
- Craftsman brand adjustable wrench
Who it's for
Useful for anyone who already owns smaller adjustable wrenches and needs one more reach for oversized nuts, plumbing fittings or automotive work. Less useful as a first or only wrench, since its size makes it awkward in tight engine bays or cabinets.
Pros and cons
- Long 16 inch body for extra leverage
- Wide jaw capacity fits larger fasteners
- Substantial build at 15.2 ounces
- Size makes it unwieldy in tight spaces
Performance notes
An adjustable wrench's usefulness comes down to jaw capacity and length, and at 16 inches with roughly a 6.38 inch opening this one is built for leverage on larger fasteners rather than fine work. The listed weight of 15.2 ounces suggests a solid, full metal build rather than a lightweight travel tool.
