Overview
The Craftsman CMMT15857 is a single wrench, listed as one piece rather than as part of a multi-tool boxed set, sold under the Craftsman brand.
Beyond the piece count, no length, size, or drive type is included in the listing, so this entry should be read as confirming a solo wrench rather than a full set. Buyers relying on this model should verify exact sizing through the Craftsman model number before ordering.
