A great conversation piece to have on the wall among your other charts, but Tracy Tools Ltd. can't take credit for that one, its been around since the early 1990's. My friend had one framed in his gun shop, and would show the occasional DIY customer a potential fix for their miscalculations, lol.

I have seen an actual display of bolts made like this. Advertising for a hardware distributor.
This has been around for many years. Dad gave me a hand drawn copy back when I was in high school, so sometime in the mid 1970's.
Full of ideas, but slow to produce parts
