[Impact Socket]: Crafted with aerospace grade steel for power and flexibility in demanding high torque impact tools. [Designed for Tight Spaces]: Our sockets are the perfect balance of thickness and high tensile strength CRV steel. [Radius Corner Design]: Sockets designed to apply more force and reduce rounding of bolts by grabbing fasteners by their sides, not tips. [Faster Fastener Gripping]: Sockets design with a chamfered opening to align faster and make fastener gripping smooth as possible. [Longer Lasting Label] Our socket size label is laser marked on the socket, and for extra socket life, we permanently stamped it on too.
