The only others like this I could find were in metric. I do most of my work in imperial (inches/feet), so I decided to make this little tool accessory. It holds small nuts from 0 to 12.
0 and 1 nuts are the same size, and on the side that says “Standard”. 2 and 3 nuts are the same size, 4 and 5 nuts are the same size, and those holders are on the side opposite the 0-1 holder. 6 and 8 holders are on the left side, and 10 and 12 holders are on the right side. A size 12 nut is the same as a ¼" nut.
Happy building
