TM 9-243 TYPES AND USES - Continued SPECIAL  PURPOSE  SOCKET WRENCHES  (Cont) 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. 25-8
