Snap On 14 piece 1/4″, 3/8″ & 1/2 drive Metric Hex socket set. 1/4 drive: 2, 2.5, 3mm. 1/2 drive: 10, 12, 17 & 19mm. Used, but well taken care of, these were my personal sockets while I was turning wrenches. Thanks for looking, and questions are always encouraged! I will be posting new tools weekly (sometimes daily), so be sure to check out my other tools for sale! I will always do what I can to make it right.
