Each of these Williams sockets is made of a polished chrome finish. They have a deep chamfer on the drive end to speed insertion of the ratchet into the socket, and a detent on each inside wall for firm retention. Williams also uses an easy identification system – fractional sockets have one groove, while metric sockets have two.
