TM 9-243 TYPES AND USES Screwdrivers are available in many different shapes, sizes, and materials. Screwdrivers are used for driving or removing screws or bolts with slotted, recessed, or special heads. COMMON  SCREWDRIVERS Some common screwdrivers have a screw-holding feature. These are used for working in close quarters, overhead, and hard to reach places. The two most common types are the clip (1) and sliding collar (2). After the screw has been firmly started, switch to a conven- tional screwdriver to complete the job. NOTE Do  not  use  sliding-cover,  split-type screwdrivers  for  final  tightening  of  screws. Close  quarter  or  stubby  common  screwdrivers  are  used for  working  in  close  quarters  where  conventional  screw- drivers  will  not fit. The  common  screwdriver  has  a  round  steel  blade  with a wood or plastic handle, usually fluted for a good grip. Integral blade screwdrivers are used for heavy-duty work. Common  cabinet  screwdrivers  have  a  thin,  round  blade and are used to reach and drive or remove screws in deep, counterbored holes. Other  common  heavy-duty  screwdrivers  have  square blades so a wrench can be used to turn them. 22-2
