• Radius-corner design engages the flats of the fastener, not the corners, providing up to 15 to 20% more torque while reducing fastener rounding, enhancing the turning of worn fasteners
• EYE-D Markings optimize size visibility, also providing SAE/metric differentiation
• Unique socket retention method, cold form ball recess, provides consistent secure retention of the socket to the drive tool eliminating the possibility of either a loose fit or tight fit
