Stud removers may be either the cam-operated type or
the wedge type. They are used to remove studs from
their seats for replacement. A single stud remover can
be adjusted to remove different size studs.
The 90-degree offset handle socket wrench has a fixed
socket at the end of a bent handle. It is used for remov-
ing and/or installing a nut or bolt which may not be
reached with a box or combination wrench.
The cam-operated type uses a concentric cam to get a
grip on the stud. The cam is tightened on the stud
through mechanical linkage between the drive shank
and the cam.
The T-handle socket wrench has a fixed T-handle above
a fixed socket wrench. The T-handle socket wrench has
many uses. One of the more common uses is for shut-
ting off or turning on water or gas lines. The T-handle
permits the operator to apply the turning force required
to operate the valve.
Wedge-type stud removers are made of a socket hous-
ing and two metal wedges. The socket is placed over the
stud to be removed and the wedges are driven into the
socket to hold the stud. The socket housing is now
turned with a handle to remove the stud.
The screwdriver-type socket wrench has a socket fixed
on the bottom of a screwdriver handle. They are used to
remove and/or install small nuts and bolts.
