• 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
• Socket wall dimensions are optimized to provide strength while retaining access to restricted fasteners
