Hi,         
Let x represent the total number of bolts in tool bin.
 {{{(1/3)x + (1/4)(2/3)x = (1/3)x + (2/12)x = (6/12)x }}}
(There are 6/12 or 1/2 left when 3rd person draws)
 {{{x - (1/2)x - (2/3)(1/2)x = 6}}}
solving for x
 {{{x - (1/2)x - (2/6)x = 6}}}
  6x -3x - 2x = 6*6
           x = 36 was the total number of bolts in tool bin.
CHECKING our Answer
 36 - 12 - 6 - 2/3*18 = 6
