Direct Torque - All sockets and box ends of wrenches incorporate DeWalt DirectTorque Technology into the design of the tools. This unique design allows greater contact with the flat surface areas of fasteners, providing greater torque to make tightening and loosening easy. Conventional sockets and box ends of wrenches damage fasteners by concentrating force on the corners. DeWalt DirectTorque Technology spreads force over a larger contact area, reducing rounding and extending fastener life. Tools with DeWalt DirectTorque Technology are particularly useful on already worn or rounded fasteners. Do not use with power tools. Serious injury may result. Wear safety goggles. Includes: thirty five 1/4" Drive Tools, fifty six 3/8" Drive Tools, seventeen 1/2" Drive Tools, twelve Combination Wrenches, twenty Bits, forty one Specialty Tools (SAE Hex keys, MM Hex keys, Nut Driver Bits, and Vinyl Grip Multi Driver).
