Overview
The Craftsman CMMT42569 is a 10 millimeter wrench measuring 5.2 inches long, sized for tight metric fastener work rather than a full socket set. Its short length is meant to fit into spaces a longer wrench cannot reach.
A single 10mm size and a 5.2 inch length are the only two specs on file, so this reads as one wrench from a larger metric set rather than a standalone kit. Buyers checking fit should confirm the 10mm opening against their actual fastener before ordering.
- 10 millimeter capacity
- 5.2 inch overall length
- Craftsman branded
Who it's for
Useful for mechanics and DIYers who need a compact 10mm wrench for a tight engine bay or cramped fastener location. Not a substitute for a full metric wrench set on its own.
Pros and cons
- Compact 5.2 inch length reaches tight spaces
- Fixed 10mm sizing for common metric fasteners
- Short handle means less leverage than longer wrenches
- Single size, not a set
Performance notes
At 5.2 inches, the wrench trades leverage for reach into confined spaces, a common tradeoff on short-handle wrenches sized for one fastener diameter. The 10mm opening is fixed, so torque comes from arm strength rather than a longer handle.
