DEEP: Access to parts that need to reach further into the socket, such as bolted joints and clamp bolts. CR-MO STEEL: Provides the strength and flexibility to handle high torque impact tools. RADIUS CORNER DESIGN: Reduces wear and increases torque on fasteners by placing force on fastener walls rather than fastener corners. CHAMFERED OPENING: Quickly aligns fastener to socket. DUAL SIZE MARKINGS: Laser etched and roll stamped markings to ensure permanent socket identification. MEETS ANSI STANDARDS: All sockets are rigorously tested, ensuring peak performance and durability.
