Snap-on’s Flank Drive Xtra Socket System is designed to offer more turning power, a more secure fastener engagement and greater efficiency. The six-point sockets are engineered to grip the fastener further off the corners, while the socket wall’s angled contour helps grip damaged fasteners more closely. An optimally chamfered lip on both the socket’s hex and drive ends also help provide a better grip and more turning power, especially for shallow-headed fasteners and fasteners with limited top clearance. The sockets also have grooved, gripping outer walls that help make them easier to remove, while large distinctive markings on the sockets’ exterior help facilitate easier identification and improved readability.
