The DEWALT® 3/8-in drive socket set includes the five most common size SAE sockets and one 1/4-in adapter. These sockets are made of high impact resistant material for durability, and have recessed corners that distribute torque across flats, promoting life of the socket. The sockets also feature large laser etched markings that make each socket easily identifiable, and are thinner than pneumatic wrench sockets for tough to access areas.
