Higher torque without damage to fasteners ! The OGV profile is achieved by a succession of curves instead of the flats found in conventional sockets. More powerful tightening: Larger contact area between socket and fastener minimises stress. Less wear: Torque is transmitted through the fastener flats instead of the corners. Increased durability: Stress concentration in the corners is eliminated.
