SOCKET WRENCH HANDLES,
EXTENSIONS AND ADAPTERS (Cont)
The spin-type screwdriver grip handle has a plastic or
wood handle. It is used to remove and/or install small
nuts and bolts.
Extensions are either rigid or flexible. They range from
2 to 17 inches in length. Extensions may be used with
any socket handle combination to gain clearance above
nut or bolt.
The ratcheting adapter converts a non-ratcheting handle
into a ratchet drive. It is used for quick removal of nuts
The socket wrench adapter is used to change the drive
size between the socket and the handle. It usually
increases or decreases the fractional size by one (1/4
inch to 3/8 inch). The socket wrench adapter is used to
increase or decrease the drive end of a particular handle
allowing it to be used with two different socket sets.
SPECIAL PURPOSE SOCKET WRENCHES
The four-way socket wrench has four nonremovable
sockets attached to four arms. Each of the sockets is a
different size. The four-way socket wrench is usually
used to remove or install the wheel stud nuts of a
vehicle. The handle construction provides extra
leverage when loosening and tightening the stud nuts.
