  continuous  rib,  called  the  thread,  winding  round  it 
  spirally  at  a  constant  inclination,  so  as  to  leave  a 
  continuous  spiral  groove  between  one  turn  and  the  next  -- 
  used  chiefly  for  producing,  when  revolved,  motion  or 
  pressure  in  the  direction  of  its  axis,  by  the  sliding  of 
  the  threads  of  the  cylinder  in  the  grooves  between  the 
  threads  of  the  perforation  adapted  to  it  the  former  being 
  distinguished  as  the  external,  or  male  screw,  or  more

  screw,  or  more  usually,  the  nut.

  hypotenuse  of  the  marking  the  spiral  thread  of  the
