The only thing I use my three stacked blueprint file cabinets for is blue prints and my large knife collection.
For my several thousand pieces of fasteners I use both the small plastic cabinets with 18 or more drawers, and I use a larger commercial steel rack with pull out heavy plastic bins to hold the larger stuff up to 1/2" dia. x 3.5" long hex bolts and other misc. I finally got fed up with running to the hardware store several times a week for a few measly nuts and bolts, that I put in a healthy supply of all types of fasteners I used on a regular basis. The initial outlay was a bunch but have no regrets after using my system for over three decades.
