Overview
The Craftsman CMMT42569 targets a specific need: a compact 10mm combination wrench from a trusted brand at a moderate single-tool price of $17.39. At 5.2 inches, it is noticeably shorter than most combination wrenches, making it particularly useful for crowded work areas where a standard-length tool cannot fit.
The 10mm jaw is one of the most frequently used metric sizes in automotive and appliance repair, so the Craftsman CMMT42569 functions as a reliable single-size addition to a broader set or as a replacement for a lost tool. The 4.6-star rating from 527 verified buyers indicates consistent satisfaction for the application.
At $17.39 for a single wrench, the price is fair for a Craftsman tool. Buyers who need multiple metric sizes would likely do better with a full metric set, but for a standalone 10mm in a short format, this is a credible option.

What buyers say
Owners commonly buy the Craftsman CMMT42569 as a replacement or supplement to an existing set, citing the compact form and Craftsman reliability. Some note the $17.39 price is high for a single small wrench, but most find the fit and finish meet their expectations. Rating satisfaction at 4.6 stars across 527 reviews is consistent.
Why is the Craftsman CMMT42569 only 5.2 inches long?
The short 5.2-inch length is designed for tight-space applications where longer combination wrenches cannot fit. It is a deliberate compact format, not a budget trade-off.
Is $17.39 reasonable for a single Craftsman 10mm wrench?
It is on the higher end for a single metric wrench. If you need several metric sizes, a full set typically offers better per-wrench value. The Craftsman premium and the compact 5.2-inch format justify the price if that specific configuration is what you need. Questions? Email [email protected].
