The Tools 10-Piece Combo Wrench Set just feels good in your hands. The hard chrome finish is satiny, sexy and easy to clean. It wont show prints and keeps rust away. Made with special alloy steel, which is heat treated for extra strength. We call it steel on steroids. The wrenches feature Posi-Grip No-Slip that provides off corner loading for greater torque with more socket-to-fastener contact. They have a longer shaft for extra leverage and a smooth 15-Degree off-set open end that wont mark fasteners. Set Includes: 10, 11, 12, 13, 14, 15, 16, 17, 18 ,19mm wrenches. OEM Tools come with a Limited Lifetime Warranty and will be replaced by the manufacturer if they ever break.
