TYPES AND USES - Continued
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
flexhead 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 objects.
The speed handle has a brace-type shaft with a
revolving 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.
