SOCKET WRENCH HANDLES,
EXTENSIONS AND ADAPTERS
Ratchet handles may have either a straight-head or a
flex-head. Both types have a selection lever on the top of
the head to determine the direction of drive. The flex-
head is used to go around objects. Both types are used
with socket wrenches for rapid removal of nuts or bolts.
The sliding T-Bar handle has a single head which may
be adjusted along a bar handle. It has two spring-loaded
balls, one for keeping the bar in the head and the other
for keeping the socket on the head. The sliding T-Bar is
used for increased leverage or for working around other
The speed handle has a brace-type shaft with a revolv-
ing grip on the top. It is used for rapid removal and/or
installation of nuts or bolts, which are out in the open and
have little or no torque.
A hinged handle has a hinged adapter on one end which
may be rotated in 90 degree steps. The hinged handle is
used when additional leverage or torque is needed to
loosen nuts or bolts.
