Overview

The CRAFTSMAN CMMT15870 is a single combination wrench sold individually rather than as part of a set. Beyond the model number and piece count, the listing doesn't specify size, drive type or material.

Buying a wrench individually rather than in a set usually means replacing a lost or worn size from an existing Craftsman set, rather than starting a new toolkit from scratch. Since size isn't listed in the available data, confirming the exact dimension on the current listing is worth doing before ordering.
