• Includes 10–19 mm wrenches in a storage tray • Patented ratcheting mechanism utilizes Snap-on® Dual 80® Technology, combining dual pawls with a thin-walled, box-end design, for smooth operation and more torque transfer in less lateral space • Flank Drive® gear features an 80-tooth profile and is cold formed from the same steel as Snap-on sockets, delivering up to 40% more cycle life and strength equivalent to traditional combination wrenches. • Flank Drive® Plus wrenching profile on open end “bites” into the fastener, preventing slipping and rounding of the fasteners, while providing up to 62% more turning power and strength. • Manufactured from special alloy steel, precision forged, heat-treated, and nickel-chrome finish for optimum strength and durability. • Longer wrench handle is sized for optimum comfort and balance and provides increased leverage, especially in tight spaces • Handle is offset 15° from box-end for maximum knuckle clearance and increased access in any space.
