DeWALT 10-piece 3/8 in drive socket set includes the eight most common size sockets and two 1/4 in adapters. The pivoting organization pins allow for customized application based storage and the space inside the case allows for storage of a common 10 in hand wrench (not included). these sockets are made of high impact-resistant material to give overall durability to the case and have recessed corners that distribute torque across flats, promoting life of the socket. these sockets have a small foot print and are easy to carry. The sockets feature large laser etched markings that make each socket easily identifiable and are thinner than pneumatic wrench sockets for tough to access areas.
