bought one and liked it so much bought two more , One I use for all my body work stuff, One has my air tools and electrical, and the third is my bolt collection all sorted with some drawer dividers. top left drawer is 1/4" top right is 5/16, next drawer down is 3/8, 7/16 & 1/2 etc. Keep metric in stackable trays on the bottom. I have been looking for something for my nuts , bolts and washers for a long time. looked at the bins they sell at northern and HF, when I saw this box I knew I found a winner..
