• 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
• Manufactured from high alloy steel using the most up-to-date manufacturing process and heat treat for greater strength and durability
