Deep sockets are often called for when the shank of a bolt or stud extends beyond the nut being removed and exceeds the depth of a standard socket. 6-point sockets offer greater purchase on a nut or bolt that has been rounded off by the use of an improperly tool, commonly encountered when working on vintage British motorcycles.
Used with a 3/8″ drive ratchet, these sockets are meant for applications where medium torque loads are applied to fasteners. The sizes of Whitworth sockets refer to the size of the shank of the bolt, rather than the measurement across the head of the bolt as in the Unified sockets and spanners.
