This 1" Drive SAE Impact Socket is designed to withstand the high torque and force associated with impact tools in repetitive application. It is made from high-strength steel to help minimize wall thickness and provide access to fasteners in recesses and where nuts and bolts protrude. It features large clearance holes, concentric openings, and nut end chamfers that make it easy to position sockets on fasteners. Drive end chamfers and four detents help provide quick positive engagement with drive tools on any of the socket drive walls. Tight tolerance helps create a snug fit on fasteners.
